Fault Codes - Fisher & Paykel DishDrawer DD60 Service Manual

7.2 Fault Codes

If there is a fault, the LED display will be displaying either a fault code or a user warning. Fault codes begin with the letter "F",
user warnings begin with the letter "A", the fault code is shown with a number which corresponds to that particular fault.
e.g. F25 ( motor loss of phase)
Some faults may lock the lid, in which case the tub must be opened by force. This should not cause damage, however do not
attempt to close the tub with force.
The following section is intended to provide information on the cause of faults in order of likelihood. After each step in the
process, the following procedure should be followed:
• Cycle the power to the device.
• Run any hardware device that has been replaced in "Hardware Output Mode"(refer to page 42 & 43) for at least 10
seconds. A long low tone played indicates a fault with the component (high pitch beeping from solenoids is normal and
expected)
• If the original fault or another fault occurs while performing steps 1 & 2, move on to the next step of the process for that
particular fault code.
WARNING! Before attempting any servicing to the product ensure the power is isolated. If replacing or removing components
or harnesses always treat the product as live to earth. Ensure all earth wires removed during servicing are correctly reattached.
A1: Water Supply
1 Is the water supply hose connected and the tap turned on?
2 If there is no water in the tub, enter the hardware output mode and run the fill valve.
If water enters the tub then the water supply is connected, however the incoming
water pressure may still be too low for correct operation.
3 Check the hose filters are not blocked, or replace the fill valve if required. Did this
clear the fault?
4 Check that the incoming water pressure and flow rate are adequate.
For installations where the water pressure or flow is low, the DishDrawer may need to
be run at a separate time to other appliances which use water, like washing machines.
Min water pressure for non water softer models: 0.03MPa (4.3 psi).
Min water pressure for water softener models: 0.1MPa (14.5psi)
5 Check that the motor rotor is undamaged, replace the motor rotor if damaged, does
this clear the fault?
6 Make sure there is no foam in the tub. If there is foam try to determine the cause i.e. is
liquid detergent being used, or has rinse aid been spilt into the tub.
A3: Tub Cannot Drain
1 Is there water in the tub?
2 Using the diagnostic hardware output mode, start the drain direction (P2), does the
product drain?. Is the drain hose blocked?
3 Is there any damage to the rotor? is there an obstruction caught in the motor rotor?
A6: No Spray Arm
1 Is the spray arm correctly located on the motor rotor? and is the motor rotor
correctly installed? Check that the wash impellor is not loose on the rotor shaft.
2 Using the diagnostic hardware output mode, start the fill valve, is it operating
correctly? If not replace the valve.
3 Check that the water pressure and flow rate are adequate.
For installations where water pressure or flow is low, the DishDrawer may need to be
run at a separate time to other appliances which use water, such as washing machines.
A7: Auto Recover Cycle
1 The product has detected excess foam in the wash tub, let the auto recovery program
run until it is complete. The wash program will resume when the auto recovery pro-
gram has completed.
