FAULT CODE POSSIBLE CAUSE WHAT TO CHECK
A61 - No Temp Increase During heating phase the temperature
will not increase min. 1°C in between
a heating time of 3 minutes.
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.
A62 - TEMPERATURE >80
DEG C
Only for FC6 model - water temp too
hot.
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.
A70 - TEMPERATURE
SENSING AT NTC.
Poor harness connection. 1.Check turbidity sensor harness.
2.Replace turbidity sensor, should be 10K
Ohm under 25 degree C.
3.Replace controller.
Turbidity sensor failed.
Main controller failed.
A80 - TURBIDITY SENSING Turbidity sensor out of range 1.Check turbidity sensor contacts.
2.Complete turbidity sensor calibration in
service mode (refer section 6).
3.Replace turbidity sensor.
A81 - TURBIDITY SENSOR
OUT OF RANGE
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.
A82 - TURBIDITY SENSOR
WITHOUT STABLE SIGNAL
Turbidity sensor 1.Turbidity sensor in sump has dirty optical
lense, clean the lens contacts.
2.Check turbidity sensor harness.
3.Replace turbidity sensor.
F90 -
C6 MODEL ONLY
Checksum communication 1.Turn the product electrical supply off at the
wall to reset and try another cycle.
2.Replace the controller if fault persists.
FA0 - Frequency consistency
checks
The frequency of the input power is
incorrect.
1.Check incoming electrical supply.
2.Replace the controller.
FA2 - Frequency consistency
checks
AD0 - Door incongruence Door lock signal 1.Check harness connection.
2.Replace the controller.
AE0 - Diverter position The position for the upper or lower
sprayarm cannot be reached within
30 sec after start of the diverter
motor
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.
