HE1Heater Error. When the temperature of the Thermistor is 80C or above for more than 3 seconds.
9ELow Water Level Error. When Low Level is detected to cause Error even after the water supply resumes after Low Level is detected for the 1st time.
bE2Button Error. When the button is pressed continuously for over 30 seconds.
bE3When IC communications between the SUB PBA and the touch button fails. Normal working at washing mode.
PEHal fLoad Error. When micro s/w is not detected for over 30 seconds after the Distributor motor starts.

3EHigh temperature Water supply error. When 80C or above is detected during water supply.
bEButton error. When the button is pressed continuously for ever 30 seconds.
dEDoor open warning. When door is open in washing period. Door is not closed properly in test mode only. Possible defect: Door lock switch, Main PBA.
CECommunication error. Communication Check between Micom is sub PBA and Touch IC is touch PBA or between Micom in sub PBA and Micom in main PBA.
PEIn cade the power of the drain pump power exceed 15W in the operation of the Drain even if it operates with 3 times.
AEWhen communications between the main PBA and the sub PBA fails for 24 seconds.
AE6When the response is not received from inverter PBA for seconds, Inverter RELAY OFF for 2 minutes. After repeated 3 times, display the check code.
1EHPS detected water level
4E5When the number of detected water supply pulses are 200 at the Non-water supply mode. Repeats water valve on/off 2 times.
9E1/9E2If blackout or DC Link voltage is high or low voltage conditions, switches to stop mode ( abnormal voltage)
7EDraining is performed for 3 minutes. Motor gear is out of order. Sensor vane is out of order. When the vane is blocked.
4C1. When the number of detected water supply pulses is less than 10 within 20 seconds after water is supplied. 2. When the target water level is not reached within 60 minutes after water is supplied.
PCWhen the location is not detected for 2 minutes after the synchronous motor operation.
tCWhen the temperature sensor data output is equal to or greater than approximatelt 4.5V or is equal to or less than approximately 0ç2V.
SDrain Error: 1.Drain Pump. 2.Water level sensor. Drain pump will drain until low level sensor is detected. If low level sensor is not detected after 60 seconds, Drain Error (5E) will blink.
LOver level water error. 1. Inlet valve 2. Overflow. Water is supplied until Over-level Error (oE) is blinked.
FLHalf load funtion error. Half load motor.
SPStorm wash function error. Half load motor.

If overflow occurs, turn off the main water supply before calling a service. If there is water in the base pan because of an over fill or small leak, the water should be removed before restarting the dishwasher.

Possible Cause:

  1. The door is not closed completely. The Start/Reset button is not selected.
  2. No programme is selected.
  3. The power cord is not connected.
  4. There is no water supplied.
  5. The control panel is locked.

  2. Clean the filter and make sure the filters are fitted properly.
  3. Use an automatic dishwasher detergent or use more detergent.
  4. The water supply pressure must be between 0.05 MPa and 0.8 MPa.
  5. Clean the spray arms.
  6. Rearrange the dishes so they have good water access and do not interfere with spray arm and dispenser operation.

Problem: Does not dry dishes well

Possible Cause:

  1. There is no rinse aid in the dispenser or not enough rinse aid was used.
  2. Multi taps were used without selecting the Multi Tap function.
  3. Glasses and cups with concave bottoms hold water. This water may spill onto other items when you are unloading.
