Fault Code Problem Solving Charts

4.8
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.
