7 FAULT FINDING PROCEDURE

If the product has an LCD display, it will be displaying either a fault code or a user warning. Fault codes begin with the letter “E”., user warnings begin with the letter “U”, the fault code is shown with a number. e.g. E2

If the product is integrated or has a wireless remote, it will be necessary to open the tub to determine the fault code. 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 fault code or user warning will be displayed on the user interface LED’s on the tub flange, refer to pages 33 & 34 for the codes.

If the code indicates a user warning “U4”, then this tub does not have a problem, the warning is to show the user that the other tub has a fault which has prevented that tub from operating.

If the code indicates either of the user warnings “U1” or “U6” there is no sub code. Otherwise pressing the START/PAUSE button will display the current fault sub code for 3 seconds before reverting back to the main fault code.

The sub code provides more specific detail on what is causing the fault, which helps in diagnosing the problem. If a sub code is being displayed, then the “Eco” LED will be on. ( refer sub code faults pages 38 & 39)

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.

NOTE: Vented integrated single product use a specific controller, ensure the correct controller is fitted if replacing.

7.1 Fault Code Problem Solving

1.This 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 have been replaced in “Hardware Output Mode” ( refer p30) 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 step 1 & 2, move on to the next step of the process for that particular fault code. Otherwise move on to section 7.2 “completing a service” on p54.

7.1.1User Warning U1 - Water Supply

1.Check to make sure that the water supply hose is connected and the tap is turned on.

2.If there is no water in the tub, enter “Hardware Output Mode” and run the fill valve (P30 & 31). If water enters the tub then the water supply is connected, however the water pressure may still be too low for correct operation. Min pressure .03MPa (4.3psi), water softener model 0.1MPa (14.5psi).

3.If the water pressure and flow rate is inadequate, try fitting a 4 litre valve ( part #529828) which may help increase the flow to the product. In cases where water pressure is too low, the DishDrawer may need to be run at a separate time to other appliances which use water, such as washing machines.

4.Check the motor rotor is undamaged. Replace the motor rotor if necessary.

5.Check the water softener filter for blockages (if fitted) refer to p24.

6.Make sure there is no foam in the tub, If there is foam try to determine the cause, i.e. liquid detergent being used or rinse aid been spilt when customer refilling dispenser. Run the product in “Hardware Output mode” refer p30 & 31 (P2 - drain pump) while the drain pump is operating, pour warm water into the tub to help flush away excess foam.

7.To exit “HO” mode, press POWER button at any time.
