Diplomat Dishwasher Fault Codes
 
Error Codes for Diplomat:
ADP8242 GC Number DW – 073 – 01
ADP8112 GC Number DW – 073 – 08
ADP8132 GC Number DW – 073 – 04
 
This Facia may not be exact; however the principles will be the same.
 
Faults on this appliance will be displayed automatically after they occur.
 
 
Error Code LED Sequence Cause
E1

Anti-Flood device activated

Water leaking

E2

Intake of too much water

Pressure switch safety level has been tripped

E3

No Heat

E4

Temperature sensor Fault

Disconnected/Open Circuit

E5 Not Filling
E6 Not Draining
E7 The appliance is waiting for a signal from a flow meter. However this appliance is not fitted with a flow meter. See below for details on how to cure this fault.
 
For an E7 fault the PCB has to be reset:
bulletWith the door open, turn the appliance ‘On’
bulletWithin 3 secs, push the program selection button ‘P’ 4 times
 

 

The test program has been selected if ‘Soak’ and ‘Strong’ LEDs are flashing. (This combination represents the test program for appliances that have a flow meter.

 
bulletIf the above LEDs do not flash after carrying out the above procedure, then switch appliance ‘Off’ and repeat process again
 

Once the above test has been activated and the LEDs are illuminated then:

 
bulletPush the program selection button ‘P’ once to select the version “without flow meter”
bulletCheck that the ‘Soak’ LED is ‘Off’ and the ‘Strong’ LED is ‘Flashing’
 
 
To complete the procedure:
 
bulletEnsure appliance is switched ‘Off’
bulletWait for approx. 10 to 15 secs
bulletSwitch the appliance back ‘On’
bulletSelect the SOAK program to test
 
E1 fault
 

This model does not have a polystyrene float to enable it to indicate water in the base tray, however there have been instances where the connector block to the float switch has been conducting, which will indicate an E1 fault on the PCB.

To rectify this fault:

 
bulletNote the position of each wire
bulletCut wires so as to remove the connector block
bulletRefit new amp tags
bulletReconnect wires in their respective positions
 
Excessive amounts of soap being used
 
If the regeneration valve is constantly receiving a 240V supply then the main PCB has to be replaced.
 
Unexplained lockout faults on the PCB
 
There are two main reasons why this may occur:
 
bulletFaulty PCB
bulletFaulty Detergent dispenser
 
In some cases this fault has also been attributed to a low Insulation fault from other components such as the circulation motor.
 
Error Codes for Diplomat ADP8342
GC Number DW – 073 – 07
 
This Facia may not be exact; however the principles will be the same.
 
Faults on this appliance will be displayed automatically after they occur.
 
 
Error Code LED Sequence Cause
E1 Door switch is faulty
E2 Not filling
E3 Not emptying water
E4

Temperature sensor Fault

Disconnected/Open Circuit

E5

Intake of too much water

Pressure switch safety level has been tripped

 
Error Codes for Diplomat:
ADP8252 GC Number DW – 073 – 05
ADP8224 GC Number DW – 040 – 10
 
This Facia may not be exact; however the principles will be the same.
 
Error codes will be displayed automatically when they occur.
 
Error Code Cause of Fault
E1 Anti-Flood device activated
E2

Pressure Switch safety level has been reached

Appliance has over filled

E3 Not Heating
E4 Temperature Sensor Faulty
E5 Not Filling
E6 Not Draining
E7

Not Draining

Appliance is looking for a Flow Meter

E8 Motor Diverter valve faulty (Only on models with alternate wash cycle)
E9

Pressure Switch safety level has been reached

Appliance has over filled

 
Control PCB does not respond (Locks Out):
 
Unexplained lock outs of the Control PCB are normally caused by either a faulty
PCB or Detergent Dispenser. However, there have been instances where this fault has been caused by low insulation on a component, e.g. the Circulation Motor, Heater.
 
Error Codes for:
 
ADP8322 GC Number DW – 073 – 02
ADP8332 GC Number DW – 073 – 06
 
 
Error Codes should be shown automatically when they occur. If the error code is not visible to the engineer, they can be accessed by starting the diagnostic test cycle:
 
bulletWith appliance door ‘Open’
bulletTurn appliance ‘On’ at the mains
bulletPush ‘Programme Selector’ button ‘P’ until the LED for Programme ‘P1’ is illuminated
bulletTurn appliance ‘Off’ at the mains
bulletPress & Hold ‘Start’ button
bulletTurn appliance ‘On’ at the mains
bulletRelease ‘Start’ button when ‘Start LED’ begins to flash
bulletPress ‘Start’ button to begin Diagnostic Test Cycle
 
Note:
 

The Diagnostic Test Cycle is designed to stop once an error code has been detected. Therefore appliance faults must be fixed for test cycle to complete.

If no error is detected the cycle will run until completion, unless it is cancelled by pressing and holding the ‘Start’ button for approx. 3 secs (this also clears the last error code).

If Diagnostic Test Cycle cannot be started i.e. ‘Start LED’ does Not flash, then the appliance has detected either an ‘F1’ or ‘F9’ fault (refer to error code table).

 
Depending on the type of controls Error codes can be shown in two ways:
 
  1. For Appliances without an LCD Display, Error Codes are indicated by a number of flashes of the ‘Start LED’ e.g. F3 fault – ‘Start LED’ flashes three time pauses for 1 sec then repeats process.
  2. For Appliances with an LCD Display the Error Code will be shown in the display.
