VIRTUAL SENSORS Description and Operation
Basic Description:.
The traditional pressure switch has been replaced by a system of "Virtual
Sensors" that will detect the presence or absence of water in the tub.
In practice, these sensors are the BLAC Wash Pump and the BLAC Drain
Pump.
The Virtual Sensors are able to detect full or empty conditions by
monitoring the operation of the BLAC wash pump and the BLAC drain
pump: By measuring the effort (energy consumption) expended power by
these motors, the Main Module can identify the exact operating situation.
See Tables below.
Virtual Sensor (BLAC WASH PUMP) Sensing Blocked Filter
If, during the wash cycle, the Wash Pump (functioning as Virtual Sensor) senses a Clogged Filters/
Suds situation, the main board will reduce the motor rpm by 20%.
If the situation stabilizes, the problem will be identified as “Suds” and the pump continues operating
at the new speed.
If the pump continues to struggle (condition 3: build-up of suds or filters clogged),
the speed will be reduced by a further 20% and the problem identified as “Clogged Filters”. If the
situation stabilizes, the pump will continue operating at the new speed.
If the problem persists, the machine will begin to top up with water until there are
5.5 litres in the tub or until the problem is overcome (whichever occurs first).
If the problem still persists (even after 5.5 litres of water have entered), the machine
will drain and the program skips to the next step of the cycle.
Drain Pump
The new Drain Pump has a BLAC motor.
The speed of this pump is controlled by the Power Module in
response to the different conditions prevailing at any given moment.
The BLAC Drain Pump's main function is to drain water from the
machine.
In addition, the BLAC drain pump (in combination with the BLAC
Wash Pump) operate as a virtual sensors.
Anti Flood Device
Consistingofapolystyrene float and microswitch.Anexcessofwater
in the base operates the float switch sending a signal to the control
module operating the drain pump and displaying a fault code on the console.

FILLING SEQUENCE (with Virtual Sensors)
Once a program has been started, the first action of the dishwasher will be to drain down until the
“D-Sensor” registers empty + 15 seconds.
Thereafter, the W-Sensor runs for 40 seconds at 1400 rpm with the bottom delivery outlet open, to
confirm that the tub is actually empty (if not, after three unsuccessful attempts error “F15” will be
displayed).
The machine then starts to fill — an operation that will be completed in two steps:
1. Static fill: the fill solenoid valve is piloted to open by the Main Module, and will admit
approximately 2.0 litres of water, measured by the Water Turbine. When this threshold is
reached, the Wash Pump (“W-Sensor”) runs at 1400 rpm with the bottom delivery outlet open,
to confirm whether or not the machine is in Full status. If the Full condition is satisfied, the
dynamic fill will start.
Note: The BLAC Wash Pump Motor running at 1400 rpm on the bottom outlet, full status will
register with approximately 1.5 litres of water.
2. Dynamic Fill: with the BLAC Wash Pump running (at 1400 rpm, bottom delivery outlet), the fill
solenoid valve is activated and held open by the Main Module until the water level increases to
around 3.5/3.8 litres (depending on the cycle selected).
If full status is confirmed by the “W-Sensor”, the machine will continue washing as normal.

Possible Filling/Draining Errors
Machine is not emptying
Once a program has been started, the first action of the dishwasher will be to drain until the
"D-Sensor" registers empty + 15 seconds. Thereafter, the "W-Sensor" runs for 40 seconds at
1400 rpm with the bottom delivery outlet open, to confirm that the tub is actually empty (if not, after
three unsuccessful attempts error "15" will be displayed).
The machine then starts to fill - an operation that will be completed in two steps:
Machine's inlet Water Tap is OFF.
Static fill: The fill solenoid is piloted to open. The Main Module doesn't receive any information from
the Turbine (because no water in entering the machine). After a short time the machine will bleep
time and Hwill be displayed, is displayed (Warning to the user that no water is entering the machine)
after a further period the machine times out and 06 fault will display.
Turbine out of Range
Static fill: The fill solenoid is piloted to open. The Main Module does not receive any information
from the Litre-count turbine. After one minute during which the solenoid valve remains open and
approximately 2.4 litres of water have entered the machine, the Wash Pump (W-Sensor) runs at
1400 rpm with the bottom delivery outlet open to confirm
W-Sensor Full status. The cycle moves on to dynamic fill.
Dynamic fill: The speed of the Wash Pump is increased to 2400/2500 rpm (depending on the cycle
selected) and the tub continues to fill until the motor torque registers at a value corresponding to Full
status, at which point the machine continues washing as normal.

Blocked Filter
1. Static fill: the fill solenoid valve is piloted to open by the Main Module, and will admit
approximately 2.0 litres of water, measured by the Litre-count Turbine. When this threshold is
reached, the Wash Pump ("W-Sensor") runs at 1400 rpm with the bottom delivery outlet open,
to confirm whether or not the machine is in Full status.
If the Full condition is satisfied, the dynamic fill will start.
2. Dynamic fill: with the Wash Pump running (at 1400 rpm, bottom delivery outlet), the fill
solenoid valve is activated and held open by the main module until the water levelincreases to
around 3.5/3.8 litres.
At this point if a fault situation is confirmed, the machine continues to fill until:
>Full status is satisfied, in which case the wash proceeds as normal;
>It the Tub contains 5.5 litre's of water, or the dynamic fill timeout is exceeded; in both instances,
theprogramskipsto the nextstep. (The programmewill completein a shortperiod andthe load
will be dirty at the end of the cycle.) No Fault code will display.
Detergent, Rinse Aid Dispenser and Oxygen Generator
Soap Dispenser / Oxygen Generator
The dispenser fitted to these models works
differently to dispensers previously found on
Hotpoint / Indesit Dishwashers.
Operation of Detergent Dispenser:
The dispenser incorporates a solenoid valve at
the rear which, when activated, opens the
dispenser to release the detergent and at the
same time releases the rinse aid.
The dispenser is activated:
1. The Solenoid is energised for one second, to release the detergent; the rinse aid will not be
released in this short space of time, because of its viscosity.
2. Once or repeatedly for a fixed duration of 10 seconds to release the rinse aid, depending on
the setting adopted by the user. Each time the dispenser is opened, 1.5 ml (1.5 cc) of rinse aid
will be released.
Possible settings:
0: Off (no rinse aid is released)
1. One pulse is generated, releasing 1.5 ml of rinse aid
2: Two pulses are generated, releasing 3 ml of rinse aid
3: Three pulses are generated, releasing 4.5 ml of rinse aid
4: Four pulses are generated, releasing 6 ml of rinse aid

ADDITIONAL COMPONENTS INFORMATION
Ozone Generator
The function of the ozone generator, is to
prevent the formation of bacteria,
consequently minimizing unpleasant smells
inside the tub and generally improving
hygiene conditions internally of the
appliance.
The component receives a power input of
220 V from the mainboard. An internal
electronic circuit is programmed to govern
the components and the duration for which
ozone is produced.
When activated to deliver ozone, the
solenoidvalveofthedeviceisopen,andthe
fan and ozone generator come into
operation.
How the Ozone Generator works as an option for preventing the proliferation of bacteria and
avoiding unpleasant smells:
The “O3” option is activated by pressing and holding the relative button. The option functions
continuously for 24 hours, alternating between ON and OFF at set intervals:
for the first three hours, the system operates 5 minutes On and 15 minutes Off, then, for a further
3 hours and 10 minutes, 8 minutes On and 30 minutes off; the time remaining until the end of 24
hours is divided into intervals of 8 minutes On and 15 minutes Off.
When the ozone generation system is not working correctly, the solenoid valve will emit
3 audible pulses each time it is activated.
If nothing is heard when activating the function, the fault is in the solenoid valve.
Turbidity Sensor
Situated in the Sump it detects the dirt level in the water and consequently selects the required
cycle content and duration when an Auto Cycle is selected.
The Turbidity Sensor is active on Programmes:
• Auto Normal
• Auto Duo Wash
• Auto Super Wash
Depending upon the soil in the water the control
module, in conjunction with the turbidity sensor
adjusts the following:
• Temperature
• Cycle duration
• Number of rinses
• Wash Pump Flexipower Motor speed
• Spray arm pressure

GENERAL DISHWASHING INFORMATION
NOTE: - Many faults occur over along period of washing incorrectly. Correcting faults may not
immediately cure a problem, e.g. several washes may be necessary to give better results.
POOR WASH RESULTS
A variety of factors influence wash results and some of the more common are listed below.
A. FOOD OR STARCHY REMAINS LEFT ON CROCKERY
May be detected by running the tip of a finger over the surface of a dish or by wiping with iodine.
This gives a blue/black colour to even the smallest trace of starch. Dried on starch or food soil
should be washed off manually before placing items back into the dishwasher.
1. Food remains not removed prior to washing
Ensure that surplus food is removed and that heavily encrusted or burnt on remains are
pre-soaked.
Ensure that Pre-Wash Programme is used if soiled dishes are being stored in the machine prior
to washing.
2. Spray arm nozzle blockage
Check spray arm and check that the strainer is seated down correctly.
3. Deposits on cups and glasses
Deposits of a sandy like substance etc., in cups and glasses in the upper section of the basket
which looks like resin are generally caused by the spray arm not functioning properly.
Possible causes of spray arm inefficiency:
Loading large or tall items in the lower basket which stops the arm revolving.
Upper spray arm split along seam.
Upper spray arm blocked.
Under dosing of powder causing foam and reducing upper spray arm water pressure.
Blocked strainers reducing water to circulating pump, therefore reducing upper spray arm water
pressure.
Low water quantity in machine.
4. Poor arrangement of load or overloading
Ensure that loading allows sufficient force of water to reach all dishes.
In certain cases it may be necessary to leave some spaces empty to ensure good results.
5. Blocked filter or kinked drain hose
Ensure that these items are satisfactory otherwise excess food soil will be present in the machine.
6. Low wash temperature
Check that correct programme is being used and that the thermostat is operating at the correct
temperature.
7. Insufficient detergent
Food soil may not be completely loosened and will not be kept in suspension in the water.
If in doubt, too much detergent does no harm, but too little in the long run does.
If dishes are heavily soiled add extra detergent. Remember - too little detergent causes foaming.

B. WHITE COATING ON DISHES AND INSIDE THE MACHINE
1. White coating or scale
Detergent not only loosens the remains of food but, together with the calcium salts in the water,
forms water-soluble compounds which prevent the appearance of the white calcium coating or
scale. Insufficient detergent may result in a white coating on dishes and the machine interior.
Unsoftened water can also cause this.
Coatings can often be removed by the following:
Take approximately 100 g of Citric Acid, a white very acidic powder which can be purchased at
chemists. Put the dishes which are to be treated into the dishwasher and fill the dispensing
container with Citric Acid instead of detergent. Then, switch on a normal programme (not the
Economy programme). The container does not take the whole amount of acid powder so interrupt
the programme before the start of the main washing cycle and pour the rest into the main body of
the tub or the inside of the door.
2. White coating on dishes that tastes of salt
Possibly causedby a poor seating regeneration valve or, most likely by a defective salt capgasket.
C. WHITE CLOUDY FILM ON GLASSWARE (THAT CANNOT BE WASHED OFF)
Thisisprobablyasurfacedeposit known as ‘silica scum’ or ‘detergent scum’ which can sometimes
form by precipitation of one of the components of dishwasher detergents.
The film can be scratched off with the tip of a needle (unlike etching). Unfortunately it can only be
effectively removed under laboratory conditions.
However, the following will prevent or slow down the deposits: -
1. Use less detergent where possible i.e.: when washing medium to lightly soiled items.
2. Do not use poor quality detergent.
3. Make sure that the rinse aid setting is correct. Lack of rinse aid could accentuate the problem.
4. Use aliquidratherthana powder detergent(fordishwashers)particularlyifglassware isconstantly
being washed.
5. Take care not to overload machine.
6. Avoid washing poor quality glassware if possible.
7. Check the salt regeneration setting is correct for the water supply.
8. Check that the machine is filling correctly.
9. Check that the machine is rinsing correctly.
10. Check that the softener by-pass is working correctly.
11. If the dishwasher has programmes of less than 65°C, use these in preference to 65°C
programmes when washing glassware.
D. WHITE DISHES TURNING PINK
1. Caused by a chemical reaction between dishwasher detergent and porcelain. This porcelain is not
dishwasher proof.
2. Formation of silicate scum on the dishes caused by using insufficient detergent.
Silicate scum absorbs iron and/or Manganese which is present in all water supplies. This colours
the scum light brown or pink.

E. POOR DRYING
1. Correct amount of Rinse Aid
The purpose of rinse aid when added to the water of a final rinse is to allow the water to run off the
dishes as a complete film so that no water-run marks or calcium are left. To enable this to happen
it is essential that the correct amount of rinse aid is dispensed. Too little does not reduce water
tension sufficiently.
Result: The water film breaks up into streaks which make shiny and clear drying impossible. After
all the rest of the water has evaporated, marks are left which are especially noticeable on glass
and cutlery as well as on items made from stainless steel.
Too much rinse aid leaves smear marks. As a result, the dishes look and feel greasy.
Setting Guide
Set dial to approximately mid position. From experience it is advisable to start with too little and to
increase the amount until perfect results are obtained. This can be verified by holding the plate
surface horizontal to incidental light at eye level. An even shine should be observed.
The automatic rinse aid dispenser should then be adjusted accordingly.
2. Opening and closing door during drying
Allows hot air to escapeand affects drying efficiency. Noticeable if the door is opened immediately
the programme ends.
F. DAMAGED DISHES
Chipping off the edges is not usually due to them rattling against one another during washing.
normally the weight of the dishes is sufficient to withstand the water pressure. Normal daily use of
dishes causes microscopic cracks around the edges which fill with water during washing. During
the heating period the water in these cracks expands and after several temperature changes the
chips may break off. Chipping may on odd occasions be caused by overloading or by loading
tightly together so that they cannot expand during heating.
G. DAMAGED GLASSES
1. Cloudy stains not caused by poor washing or drying, may be due to ring structures in the glass.
These are minute cracks due to stress created during the manufacturing process. Particles may
be washed off by hot water, leaving the surface with an etched and cloudy look. Similar results
occur duringhand washing but by using lower wash temperatures and milderdetergents the effect
takes longer to show.
2. Etched glassware can also be attributed to 100% softened water that is produced from a water
softening plant that may be installed in the home. In this instance the customer can negotiate with
the manufacturer of the softening plant to install a by-pass system to feed back approximately 5°
of hardness into the water supply, or put the appliance back on to the mains water supply and use
salt as required.
H. CUTLERY TARNISHING / DISCOLOURING
1. Silver cutlery tarnishes when exposed to air. Stainless steel cutlery may show a coating on its
surface after several washes if water has been allowed to evaporate on it, e.g. if incorrect dose of
rinse aid is used. Electrochemical reactions also have an effect and mixing various grades of
stainless, bronze plated and silver cutlery will cause problems.

2. Nickel Silver (German Silver) is an alloy of copper, nickel and zinc, and when subjected to heat in
dishwashing solutions the metal acquires a yellow colour. Maintaining this alloy in attractive
condition requires frequent polishing and it should not be washed in a dishwasher.
3. Pits and rust marks on stainless steel cutlery can usually be attributed to inferior quality stainless
steel or the finished article not being highly polished during manufacture.
Certain food soils have a damaging effect on the protective coating of stainless steel, particularly
foods containing vinegar, fruit and ordinary table salt.
Itshouldbenotedthat stainless steel should not be left in the humid atmosphereof the dishwasher
for too long after the end of the programme, since this denies the protective coating the healing
effect of oxygen.
4. Bronze or bronze plated cutlery is subject to rapid tarnishing and should not be washed in the
dishwasher.
J. ALUMINIUM COOKING UTENSILS
Bright aluminium utensils may discolour or tarnish due to alkaline attack caused by certain
minerals in the water. Removing these utensils before the final heated rinse should prevent further
problems.
Certain coloured aluminium utensils may discolour and should be washed manually.
K. RUSTING INSIDE THE MACHINE
Normally caused by migration of rust from non-stainless steel slivers alien to the machine or from
external non-stainless steel nuts usedfor fixing heater clamps. General surface rusting may occur
along the seams of the tub and can usually be removed by using a proprietary cleaner like Solvol
Autosol or 3-in-1 Chrome Cleaner.
L. INTERNAL WHITE PLASTIC PARTS OF THE MACHINE TURNING ORANGE OR PINK
Dark red coloured earthenware can sometimes produce this effect by migration of the colouring.
More common, is dishware being loaded with large amounts of tomato ketchup / juice present or
the precipitation of the iron content in the water causing staining because of insufficient detergent
and/or rinse aid dosage. The staining is not harmful but cannot be removed.
M. RAINBOW COLOURING ON STAINLESS STEEL INTERIOR AND COOKING UTENSILS
Usually caused by consistent underdosing of detergent, particularly if liquid detergent is being
used.
N. BLACK MARKS ON CHINA
Usually caused by metal marks from spoons and knives. It can normally be removed by soaking
the china in a mild bleach solution and washing or by gently rubbing with metal polish, wiping dry
then washing.
