Program Functions
Limits:
nTo ensure the correct operation of the washer, values must be
within certain limits.
nProgramming functions into a washer that does not have the
associated function will cause error codes during operation.
nIf a programmed value is outside the programmed limits,
the default program value will override the programmed value.
Programming the Water Temperature:
– Minimum value: 34°F (1°C)
– Maximum value: 113°F (45°C) for PREWASH and SOAK,
and 196°F (92°C) for the WASH Sequence.
– For RINSE, FINAL RINSE, and SPRAY, no temperature can
be programmed.
Programming the Water Inlet Valves:
nDepending on the programmed temperature the water inlet valves
are suggested.
nWhile the tub is filling with water, the computer controls the water
temperature by switching on and off the hot and cold water inlet
valves.
nFor washers with a Top Soap Dispenser, you must consider that
by programming the water inlet valves, you are also selecting the
Soap Box at which the soap must be added.
nIf you want to program a Wash Sequence with:
– Cold water: Only cold inlet valves must be programmed.
– Warm or hot water: Cold and hot inlet valves must be
programmed.
Top Soap Dispenser washers:
The cold water inlet valves
Inlet Valve 1 Corresponds with soap box for Prewash.
Inlet Valve 2 Corresponds with soap box for Wash –
powdered detergent.
Inlet Valve 3 Corresponds with soap box for Wash –
liquid detergent.
Inlet Valve 4 Corresponds with soap box for Final Rinse.
Inlet Valve 7 Is a direct inlet valve and speeds up the
water fill process.
Programming the Drain sequence:
After programming the Wash Sequence, program the
Drain/Extraction sequence.
nDrain, or
nExtraction, or
nNo Drain, or
nStatic Drain, or
nReversing Drain.
Then program all related functions of the Drain/Extraction
sequence. The available functions are:
nSequence Time (length of step)
nSpeed
nDrain valve 1–2
It is also possible to skip a sequence between two other
sequences by programming No Wash or No Drain.
Example: The No Drain sequence should be programmed
between a Wash and a Cool Down Sequence.
NOTE: See Programming for more information on sequences.
Tumble Sequence:
nThe wash cycle always ends with a Tumble Sequence.
nThe Tumble sequence takes 30 seconds, then the program is
finished and the door can be opened.
nThe Tumble sequence cannot be skipped.
The hot water inlet valves
Inlet Valve 5 Corresponds with soap box for Prewash.
Inlet Valve 6 Corresponds with soap box for Wash –
powdered detergent.
Inlet Valve 8 Corresponds with soap box for Wash –
liquid detergent.
See the schematic diagram supplied with the washer for
additional information on inlet valves.
How to Select Inlet Valves:
EXAMPLE:
nFor a Prewash: Programmable temperature: 34–113°F
(1–45°C)
Inlet Valve 1 (cold) and/or for Prewash
5 (hot) and/or 7 (cold) Direct Inlets
nFor a Wash: Programmable temperature: 34–198°F
(1–92°C)
Inlet Valve 2 (cold)
and/or 6 (hot) Soap box for
and/or 7 (cold) Wash –
powdered
detergent
Direct Inlets
n For a Rinse: Inlet Valves 1 + 2 + 7 (cold) No Soap
n For a Final Rinse: Inlet Valve 4 and/or 7 (cold) Soap box for
Final Rinse
Direct Inlets
NOTES:
nWater inlet 7 must be used for washers with laundry
product supply pumps because the liquid is added at
the direct water inlet channel.
nIf the water recycling feature is used, the water recycling
supply must be connected to Inlet Valve 5 or 7.

10
Programming the Water Level:
Water level Limits
nSee “Water Setting Values for Different Washers” because
these values are different for each Machine Type.
nThe minimum value is above the temperature sensor.
nThe maximum value is half the washer drum.
Normal Low Level, Normal High Level
nThe Normal Low Level is recommended for the PREWASH,
WASH, and SOAK sequences.
nThe Normal High Level is recommended for the RINSE and
FINAL RINSE Sequences.
nAt the Cool Down sequence, the washer computer makes use
of a low water level and is draining the water automatically.
nAt the Spray sequence, the Drain valve stays open.
Wet Cleaning selection Configuration Menu
n It is possible to program a level below default minimum
programmable level. (See table A-3).
NOTE: Normal high water level is recommended for woolens
and delicate linens.
Programming the Wash Speed:
nStandard reversing Wash Speed is between 40 and 50 RPM
(see table A-5).
nFor some special applications the drum should only turn
very slowly.
Speed Limits:
nThe minimum programmable Wash Speed is 10 RPM.
nThe maximum programmable Wash Speed is 40–60 RPM,
depending on washer size.
Programming Extraction Speed:
nSee Table A-5 for maximum and minimum spin speeds. The
limits differ depending on the maximum allowed g-force at high
spin for each Machine Type.
nExtraction = 150–1165 RPM
nBetween 90 and 150 RPM (verify exact value in table A-5)
the washer computer is not allowed to program a steady
speed, to avoid excessive vibration.
Speed Limits
nRefer to table A-5 for minimum and maximum speed limits.
The limits differ depending on the maximum allowed g-force
at high spin for each machine type.
Programming Supplies:
nUp to 4 supplies can be programmed at the same time in a
sequence.
nIf liquid soap pumps were installed on the washer, these
pumps will be activated by programming a time value for the
corresponding supply signal 1, 2, 3, 4, 5, 6, 7, or 8.
nThe maximum programmable time is 99 seconds per sequence.
nIf the time is 0 seconds then the supply will NOT be activated
during the wash process.
NOTE: If more than 4 supplies are needed in the same step, run
the step twice with half the water volume in each step. Use the
NO DRAIN sequence between the steps so the water does not
drain out.
Programming the Motor On and Off Times
for Reversing
n The default Reversing Motor On and Off Times at Wash Speed
is 12 seconds on and 3 seconds off.
n For Delicates and Woolens, it is recommended to program
a Gentle Wash action with a On time of 3 seconds and an
Off Time of 12 seconds.
Programming the Sequence Time
n The sequence time starts running after the programmed water
level is reached.
n If the Wait for Temperature feature is selected, the sequence time
begins only after the programmed temperature is reached.
NOTE: The Wait for Temperature feature must be Off unless
there is an auxiliary heat source on the washer.
n For a Cool Down Sequence, the programmed time corresponds
with the time for decreasing the water temperature.
TIP: A cool down of 3 minutes must be programmed. To avoid
garment shrinkage, it is recommended to program the time so that
the temperature will decrease with about 5°F (3°C) for each minute.
Buzzer
n The Buzzer should be programmed when a running wash
cycle needs to be interrupted.
n The Buzzer will be activated to alert the operator.
n In most cases, the operator interrupts a program to fill
the Soap Box an additional time.
n The program interruption will always occur at the end of
a step.

11

When the PC is connected to the washer, the data is sent and
stored on the PC.
• “Data PC”: sends continuously all wash cycle data to the PC,
where it is stored.

Load Cell Calibration … Load cell calibration shows current weight which is applied to each oft the load cells.
When the message “Calibrated” appears in the middle of the screen, the calibration
process has finished. For further information, read the weighing system manual.
Expected Free Weight This value states the weight of the washer. This value is used to verify correct function
of the weighing system. If the currently measured weight is out of range, a diagnostic
error appears.

Water Level Water consumption programmable in (units) or liters. If units are selected, the water
consumption is higher than when liters are selected. The system measures the exact
amount of water in liters when liters are selected.
Units Units/
Liters
Correct Linen Absorpt. If liters are selected, there may not be a sufficient amount of water for the prewash
because a dry load may absorb a large amount of water. This problem may be solved by
selecting “Linen absorption correction”.
An increased amount of water will then be fed into the washer for the prewash cycle.
No No/Yes
Automatic Level Adjust. If the amount of weighed load in the washer is smaller than the washer’s capacity,
the washer will run automatically with a reduced amount of water. This will reduce the
washer’s water consumption.
No No/Yes
Automatic Soap Adjust. Similar to Automatic Water Level Adjustment. Also the time value of the liquid soap
signal is adjusted in relation to the amount of weighed load – this will reduce the
washer’s liquid soap consumption.
No No/Yes

*Automatic Cool Down
nTo avoid mechanical temperature shock and to extend the lifetime of your washer, after a hot wash, cold water is injected bit by bit.
As a result at the end of the hot wash, the temperature will be lowered to about 65°C (150°F).
nThe automatic cool down function will only be functional if a hot wash with a temperature above 65°C (150°F) has been
programmed and if a cold water inlet valve is programmed in the next step. When a Cool down sequence has been programmed,
the automatic cool down will not function.
nThe automatic cool down differs from a normal cool down sequence. The purpose of a normal cool down sequence is to avoid
the shrinking of the garments. (Takes more time).

Overfill Detection An error message is generated if the water level exceeds the
programmed water level by more than the programmed number
of units (Err 12). If the washer uses steam heating, the steam
installation should have adequate power to quickly heat the
water. Slow heating will raise the water level and also cause
increased energy and laundry product consumption. Reduce the
programmed water temperature to the minimum level necessary
to achieve satisfactory results.
