2. The Inlet Hose is twisted.
3. The Filter of inlet valve clogged by impure water.
4. The Inlet Water Valve is normal ?
5. The water pressure is very low. ( below 0.5 kgf/ )
6. Inlet valve is blocked by safety device for leakage sensing.(In case of Inlet Valve).

Remedy

• Open the Water Tap.
• Repair the Inlet Hose.

1.Close the Water Tap.
2.Unscrew the Inlet Hose (Inlet Valve side)
3.Clean the Filter of Inlet Valve.
> Replace or repair the Inlet Valve.
> Check the water remain on the base.
1.Check the point of damages and repair or replace the related parts.
2.Disconnect the inlet hose to dishwasher to unlock the safety valve.
ERROR DISPLAY [OE]
Drain error.
Condition: Not fully drained out in spite of 5 min. drain operation.
Possible causes:

1. The Filter clogged.
2. The Drain Hose twistec or blocked.
3. The Drain Pump/Motor or circuit is troubled.

Remedy

• Clean the Filter.
• Remove the cause of twist or block.
• Replace the Drain Pump/Motor or repair the Circuit.

ERROR DISPLAY [E I ]
Leakage error.
Condition: The water level in Tub goes down during operation.
Possible causes:

1. Water leakage in Hose connections.
2. Water is leaked by damages.
3. Impeller of the washing Pump is worn away.
4. The Thermal Protector of the washing motor is functioned

Remedy

• Replace the connections of Hose.
• Check the point of damages and repair or replace the related parts.
• Replace the washing pump.
• Check the applied voltage.

ERROR DISPLAY [ F E ]
Excess error.
Condition: Excessive water is supplied than normal water level.(Automatically drain Pump operated.).
Possible causes:

1. The Inlet Valve is troubled.
2. The Air Break is troubled.
3. The Sensor Assembly is troubled.
4. The Controller is troubled.

Remedy

• Replace the Inlet Valve.
• Replace the air breaker.
• Replace the sensor assembly.
• Repair or replace the controller.

i20 error code means:
Water is not pumped off and could be:

• Fault with discharge pump

• Discharge pump deenergized (faulty wiring or no activation by electronics)

• Obstruction/blocking (filters in the appliance, discharge opening in discharge trough, discharge pump, discharge hose, siphon, cover plug at siphon connection not removed during first commissioning)

• Discharge hose bent or connection height above 100cm

• Ball valve in discharge trough glued / blocked (discharge pump does not aerate)

or water level inside appliance is not detected and than
could be:

• Pressure controller faulty

• Pressure controller hose obstructed or bent

• Insulation fault with heating element

This is not error code. If a fault occurs on your device it will be displayed in hexadecimal code for example:
Newer models: i10, i20, i30 ....... i90, iA0,.............iF0
Older models: A0, A1 ........ A9, AA, Ab,............. Af
or C0, C1 ........ C9, CA, Cb,........... Cf
Because that I believe that the digit number "155" that you see on the display means the duration time (minutes) of selected program. Also see in user manual how to cancel selected program and choose new one.

The most common cause of a fault "i10" is closed valve on the water supply line. So this failure indicates a problem with filling of water.
Possible error causes:
Closed water tap, Inlet valve faulty, inlet hose bent, softener system clogged, pressure switch or pressure switch hose obstructed or leaking, wiring from pressure switch to printed circuit board (PCB), wiring from inlet valve to PCB and finally PCB.

If the END or DRYING indicator on the programme progress display is flashing, you can probably rectify the fault yourself.
After rectifying an END or DRYING fault, press the button for the wash programme that has been started.
The wash programme continues. If the fault is displayed again, than check water leakage in the battom of dishwasher.

Malfunction: END and DRYING on the programme progress display are flashing simultaneously.
Possible causes: The leak prevention system has been triggered.
Remedy: Try to find and repair water leakage otherwise close the tap and call customer service.

Matthew, in most cases when a circuit board repeats the same action over and over, there was a short and loss of communication with associated controllers. Obviously you have power to the control unit, so that means the instructions from the controller to the solenoids is lacking. You are correct in assuming the board needs replacement, however you must determine is the cost for replacement is worth the time and effort. An old machine means one repair after the other. If its relatively new; then it may be worth it.

If you open a sidepanel and look at the bottom of the machine you see a brown device with a piece of white foam,this is the leak prevention system.
Push foam down and the error code should be cleared.
Make sure you there's no water left on the bottom of machine
