  • E42: Flow rate is too high.

Causes:

  • Damaged wire harness.
  • Water inlet valve failure.
  • Faulty air gaps were integrated.
  • Faulty reed-switch.
  • The main board failed.

Solutions:

  • Check the wire harness connector.
  • Verify the functionality of the water inlet valve.
  • Check the turbine of the flowmeter and replace it if necessary.
  • Check the reed switch and replace it if necessary.
  • Check the main board.

E50: Communication error (Same as F50 error code)

Related error codes:

  • E51: Communication failure between the main PCB and BLDC motor
  • E52: Communication failure between the main PCB and user interface board

Causes:

  • Damaged wire harness.
  • The door harness failed.
  • Faulty user interface board
  • Faulty BLDC wash motor board
  • The main board failed.

Solutions:

  • Repair and/or replace the wire harness connector.
  • Replace the door harness.
  • Check the UI board and replace it if necessary.
  • Check the BLDC wash pump board and replace it if necessary.
  • Replace the main board.

E60: Heater element error (Same as F60 error code)

Heating temperature increases.

Causes:

  • Faulty harness on the heater.
  • Faulty overheat protection (high-limit self-reset and/or non-reset)
  • Faulty heater element
  • Faulty motor.
  • Blocked rotor.
  • Faulty main PCB

Solutions:

  • Repair the heater element harness and replace it if necessary.
  • Check the heater element resistance.
Electric part nameOhmic value
Heater assembly30 Ω
  • Check the overheat protection:
Electric part nameTemperatureOhmic value
High-limit (self-reset)[-∞°C to 100°C]0.1 ~ 1 Ω
High-limit (self-reset)[101℃ to +∞°C]∞ Ω / OL
High-limit (non-reset)[-∞°C to 205°C]0.1 ~ 1 Ω
High-limit (non-reset)[206℃ to +∞°C]∞ Ω / OL
  • Check the BLDC rotor magnet and/or winding resistance.
Electric part nameOhmic value
BLDC wash motor (between: UV = UW =VW)~ 51 Ω
  • Check the main board.

E70: NTC thermistor error (Same as F70 error code)

Causes:

  • Faulty wire harness connector
  • Faulty thermistor (turbidity sensor)
  • Faulty The main board

Solutions:

  • Repair the wire harness connector and replace it if necessary.
