POSSIBLE CAUSE
During heating phase the temperature
will not increase min. 1°C in between
a heating time of 3 minutes.
Only for FC6 model - water temp too
hot.
Poor harness connection.
Turbidity sensor failed.
Main controller failed.
Turbidity sensor out of range
Turbidity sensor
Turbidity sensor
Checksum communication
The frequency of the input power is
incorrect.
Door lock signal
The position for the upper or lower
sprayarm cannot be reached within
30 sec after start of the diverter
motor
WHAT TO CHECK
1. Check the harness between heater element
and main board.
2. Measure the wattage when heater is
actiavtes in service mode "A6".
3. Measure the resistance of heating element.
4. Change the wash pump.
5 .Check the mainboard.
1.Check the water temperature in the
dishwasher when the error alarm happened.
2. Check the trubidity sensor.
3. Check the harness between turbidity
sensor and mainboard/heater element and
mainboard.
4. Check the wash pump & intergrated
heating element.
5. Check the mainboard connections.
1.Check turbidity sensor harness.
2.Replace turbidity sensor, should be 10K
Ohm under 25 degree C.
3.Replace controller.
1.Check turbidity sensor contacts.
2.Complete turbidity sensor calibration in
service mode (refer section 6).
3.Replace turbidity sensor.
1.Turbidity sensor in sump has dirty optical
lens, clean the lens contacts.
2.Check turbidity sensor harness connection.
3.Replace turbidity sensor.
1.Turbidity sensor in sump has dirty optical
lense, clean the lens contacts.
2.Check turbidity sensor harness.
3.Replace turbidity sensor.
1.Turn the product electrical supply off at the
wall to reset and try another cycle.
2.Replace the controller if fault persists.
1.Check incoming electrical supply.
2.Replace the controller.
1.Check harness connection.
2.Replace the controller.
1.Try to confirm whether the lower and upper
spray arms can work properly when activate
the A8 in service mode.
2.Try to check the harness between the
diverter and mainboard.
3. Change the diverter valve.
4. Change the mainboard.
