Fault Code Problem Solving Charts

The following charts can be used as a guide to help locate faults in a DishDrawer™.
F1 Flood Detected
The bottom controller flood detector circuit has been activated.
The product will abort the wash program, log the fault, start the drain pump, and report to the user.
Neither tub can be used until the fault is cleared.
PRIMARY ACTION
- Determine if a flood actually occurred? Is there water in the base of the machine?
SECONDARY ACTION
If water in base.
- Determine where the water has come from, check the following:
Check for the lid not closing (lid actuators), overfilling (spray arm correctly fitted and flapper shutting off, rotor
correctly fitted) or foaming (rinse aid spill or wrong detergent (liquid or tablets) used, not draining (rotor or motor
housing damaged, drain hose blocked / crushed), lid seal damaged, dispenser or water softener seals leaking,
damaged fill or drain hoses, tub leaking around heater plate or motor seals, drain hose o-ring at connection to
motor, yoke pegs broken or yoke jammed at front or rear, oversize dishes, inlet hose connection to water inlet valve
leak (washer not fitted, connection not tight) water inlet valve not shutting off.
- Mop up water in the chassis base before attempting to restart.
TERTIARY ACTION
If no water in base
- Check the chassis harness connection to the PCB mains filter.
- Check for corrosion/dirt around the flood sensor on the side of the mains filter housing.
- Replace the PCB mains filter.
F2 Motor Not Rotating
The controller has not sensed the motor rotating.
The product will pause the wash program, log the fault, and report to the user.
PRIMARY ACTION
- Check the rotor is free to turn.
Check that power is available at controller (e.g. do the lid actuators run in diagnostics).
-
SECONDARY ACTION
- Check whether the rotor is not moving or is vibrating in diagnostics.
- If vibrating, check the hall sensor is properly fitted, check that the motor stator connections are OK.
- If not moving, check the connections at the controller and the motor.
- Check the resistance of the motor windings.
TERTIARY ACTION
- Check if a replacement hall sensor solves problem.
- Check if a replacement controller solves problem.
- Check if a replacement PCB mains filter solves problem.
