A = The answer
F1 The flood switch is activated for more than
6 seconds
1. Did a flood occur? (N.B. The flood may have
dried up)
2 Is the lid sealing on the tub correctly?
3 Is there a high water level in the tub?
4 Is the water valve leaking?
5 Is the DishDrawer priming correctly?
6 Is the spray arm split?
7 Is the spray arm running freely?
8 Is water leaking from a split inlet or drain hose? »A
9 Is water leaking around the heater plate O rings.»A
10 Carry out more testing to locate the source of
the leak.
11 The drain hose may have been blocked or
partially blocked.
12 Is there condensation or foreign matter
around the chassis flood switch PCB?
13 If power fails to the bottom tub or if the bottom
controller is faulty it will cause the top tub to F1 »A
14 Substitute the Chassis PCB
F4 No temperature increase has been sensed
1 Does the element heat in diagnostics?
2 Test the resistance of the element at the plug
on the controller, is it OK?
3 Is the plug making a good connection onto
the controller?
4 Replace the controller.
5 Is the wiring and the edge connections down
on the element OK?
6 Test the resistance of the element and replace
if necessary.
7 Is the resistance of the temperature sensor
measuring from the plug on the controller OK? »8
8 Replace controller.
9 Is the wiring and the edge connections down
to the temperature sensor OK?
10 Replace the element.
F9 Electronics Failure (EEPROM access error)
1
Isolate the power to the DishDrawer for
10 seconds then retry, does the fault clear?
2
Replace controller
U1 Machine Failed to Prime with Water within a Given Time
1 Is the tap turned on?
2 Is the spray arm in place? (spray arm may
have been refitted since U1 fault occurred)
3 Activate the water inlet valve in diagnostics.
Does any water enter the machine?
4 Is the impellor on the rotor slipping?
5 Is the supply water pressure above
30Kpa/4.3p.s.i?»
6 Check the water inlet hoses & valves for an
obstruction.

F2 The motor is not sensed to be rotating
No
1
Is the rotor jammed?
2
Free jammed rotor, check for damage to rotor

3
Is the stator wiring from controller OK?
»6
Check stator windings for correct resistance
»5
are they OK?

4
Repair wiring or replace stator as required.

stator correctly and plugged onto the
»9
controller with a good connection?

Poor Dry Performance
»A
1 Is the customer complaining of plastic items not
»A
drying? (due to their low thermal mass plastics
give inherently bad drying performance)
»9
2 Is the customer using rinse aid?
»A
3 Is the customer using Fast or Eco cycles?
»A
4 Due to lower final rinse temperatures dry
»A
performance is compromised when using
Fast & Eco cycles (there is less residual
heat for drying at the end of the cycle)
5 Advise the customer about the use of rinse aid
to improve dry performance.
6 Is the rinse aid setting high enough for the
No
water hardness in the area? (turn the rinse
agent up to a high setting)
»2
7 Check the rinse aid dispenser in diagnostics to
make sure it is dispensing the correct amount. »A

7 Minimum incoming water pressure for correct
No
DishDrawer operation is 30Kpa /4.3p.s.i
