2.2 Danger Warnings
Unless the machine has been isolated from the supply
there will always be potential for mains voltage to any
components in the machine.
2.3 Warnings
DO NOT run the machine if there is no salt in the salt
reservoir, as this will allow lime scale to build up, also any
lime scale will invalidate your warranty.
DO NOT add any chemicals, such as detergent or rinse
aid to the reservoir. These will cause damage to the
machine.
2.4 Cautions
Only use granulated salt (max. grain size 5 –7 mm). Salt
tablets are not suitable.
If the reservoir cap is not properly secured, water and/or
chemicals can leak in or out of the unit causing damage
to the machine.
Repairs to the machine should only be done with the
mains supply isolated.
Any changes made to P30 will not be saved if power to the
machine is disrupted before completely exiting service
mode.

Item
Description
1
Heating indicator
2
Cycle indicator
6.1.1 Heating Indicator
This will illuminate GREEN only when following condition is
achieved:
•Wash tank water level full
•Rinse tank water level full
Refer (►8.2) for more options.
If one of these has not been achieved the indicator will flash
AMBER to indicate that the machine has not achieved these.
6.1.2 Cycle Indicator
This will illuminate BLUE when a cycle has been requested. The
cycle will then start when the above interlock requirements have
been achieved. This will also flash BLUE during the drain process.
In certain serious error conditions (►8.5) this indicator will
illuminate RED and the machine will turn off.
6.2 Fill and Heat
6.2.1 Pressurized Fill and Heat
Pressurised machines fill and rinse using the solenoid valve and
site water pressure. These machines will fill in the following
manner:
1) Activate solenoid valve until the wash air pressure
sensor reads a minimum level.
2) Heat the rinse tank to a specified transfer temperature;
this is lower than the rinse temperature to ensure that
the wash tank is not too hot after the fill cycle.
3) Activate the solenoid valve to transfer water through
the rinse tank to the wash tank for a specified time.
4) Repeat steps 1 to 3 until the wash tank is full.
5) Once wash tank water level is achieved, GREEN lamp
should illuminate.
6) In the background machine will continue to heat until
the rinse boiler and wash tank have both reached the
specified temperatures.
The following flow diagram shows a representation of this.
6.2.2 Unpressurized Fill and Heat
Unpressurised (air gap) machines fill and rinse using a rinse
booster pump; this means that the rinse is not reliant on the
incoming water pressure. These machines fill in the following
manner:
1) Activate solenoid valve to fill rinse tank.
2) When rinse tank has reached the minimum level it will
start to heat to a specified transfer temperature; this is
lower than the rinse temperature to ensure that the
wash tank is not too hot after the fill cycle.
3) Activate the rinse booster pump to transfer water for a
specified time.
4) Repeat steps 1 to 3 until the wash tank is full.
5) Once the wash tank has reached a minimum level this
will begin to heat if required while the rinse tank is
refilling.
6) On machines with water softeners fitted the machine
will calculate the volume of water that has passed
through the unit and activate the regeneration process
as required.
7) Once wash tank water level and Rinse tank water level
is achieved, GREEN lamp will illuminate.
8) In the background machine will continue to heat until
the rinse boiler and wash tank have both reached the
specified temperatures.
Below is a flow diagram to represent this.

6.3 Wash and Rinse
If a cycle is requested when the machine is in standby the wash
and rinse, process on all machines, follow the below procedure:
1) BLUE lamp is Illuminate on cycle indicator.
2) Starts the wash cycle with wash pump activated. Soft
start runs for first 6 seconds.
3) Once the wash tank and rinse tank has achieved the
interlock temperature (P41&P51) and the wash time has
elapsed, Wash pump will be deactivated. If the interlock
temperature are not satisfied during wash cycle time
than it will extend the wash cycle till it has achieved it.
4) There is a pause of 8 seconds to allow the wash tank
water to drip down back in wash tank.
5) Completes the rinse cycle for the specified time (P60)
with activation and deactivation of Rinse pump.
6) There is a short pause after the rinse to allow water to
drip down then the Cycle indicator will turn off.
Below is a flow diagram to represent this.
Refer (►8.1) & (►8.2) for more information on Parameters P41
& P51 and interlock options. Please note if condition for either P41
or P51 not met during specific wash cycle time than it will extend
the wash cycle time till it satisfies the conditions.
6.4 Drain
The drain of the machine functions in two ways:
1. It monitors the water level in the wash tank and drains
away any excess water at any time.
2. If the machine is turned off and the drain cycle is
selected, this function will follow the below process:
a. Start draining the machine. BLUE lamp
flashes to indicate drain cycle.
b. Once the water reaches the minimum level in
the wash tank an “Assisted clean” function will
transfer water from the rinse boiler in the
same fashion as it fills while continuing to
drain (If the door is open at this time the
“Assisted clean” will be cancelled).
c. Once the wash tank reaches a minimum level
again it activates a timer to drain out the
remaining water.
Drain flow diagram to represent this.
6.5 Chemical Dosing
The machine doses chemical at two different stages:
1. While filling the machine:
a. The detergent is dosed into the wash tank
with each transfer. At the end of the fill the
rinse aid is dosed into the rinse tank.
2. While cycling the machine:
a. When a cycle is selected the detergent will
dose into the wash tank. This will not occur on
the first cycle after filling the machine.
b. After each cycle the rinse aid is dosed into the
rinse boiler for the amount of water used.

6.6 Water Softener Unit
On machines with the integral water softener fitted the machine
will monitor the amount of water passing through the resin of the
softener unit and regenerate at intervals required by the water
hardness setting.
The regeneration process passes salt water into the resin, allows
a contact period for the salt to ‘scrub’ the resin then flushes this
salt water out the waste.
Re-fill salt indicator will flash to indicate water softener
needs salt re-filling. For Salt specification and unit installation
refer to operation manual for more information.
