20 _ Troubleshooting
Error Type Display Causes Remarks
Door Error
(Before
operation)
- A switch contact error because of a deformation of the
doorhook.
- When the door is pulled by force.
When the door is opened after starting
operation.
(UnlockFail)
- Thedoorlockswitchterminalisconnectedincorrectly.
- Thedoorlockswitchterminalisbroken.
- This occurs intermittently because of an electric wire
leakage.
- Main PCB fault
(LockFail)
Water Leakage
Error
- Theairhoseisoutofplaceandwaterleakageoccurs
during the spin cycle.
- Waterleakageoccursatthefrontwithfoaming
because of too much detergent.
- Waterleakageoccursbecausetheconnectinghose
to the detergent drawer is connected incorrectly.
OverowError
- Water is supplied continually because the water level
detectiondoesnotwork.
- Because the drain hose is clogged and there is
aninjectionerror(atanarrowsection),thewater
leveldetectiondoesnotworkandwaterissupplied
continually.
- Water is supplied continually because of freezing or
because there is foreign material in the water supply
valve.
- This error may occur when the water level sensor is
degraded.
This error occurs because the water level
sensor terminal is out of place.
Temperature
Sensor Error
- The washing heater in the tub has an error.
(Contacterror,temperaturesensorfault)
- The connector is connected incorrectly or is
disconnected.
Heater sensor fault.
: When the connector is connected
incorrectly or has a wire disconnected or
contact error.
Unbalance
Error
- Aslaundrycausesthiserror,checkthelaundry.
- Find the reason for the imbalance and solve it as
directed in the user manual.
Foaming
Detected
- This occurs when too much foaming is detected.
It is also displayed while foaming is removed.
Whentheremovalisnished,thenormalcycle
proceeds. “Sd” or “SUd” is displayed when too much
foaming is detected and “End” (WA456*) / “En”
(WA422*,WA400*) is displayed when the removal of
thefoamingisnished.
(This is one of the normal operations.
It is an error for preventing non-sensing faults.)
MEMS error
- If the output from the MEMS sensor is over 4.5V or
under0.5Vanditcontinuesfor5seconds,thiserror
occurs.
1.ChecktheMEMSsensorandPBA.
2.Checkthewireconnectorterminals.
