Error Type
Display
Causes
Remarks
Door Error
(Before
operation)
- A switch contact error because of a deformation of the
door hook.
- When the door is pulled by force.
When the door is opened after starting
operation.
(Unlock Fail)
- The door lock switch terminal is connected incorrectly.
- The door lock switch terminal is broken.
- This occurs intermittently because of an electric wire
leakage.
- Main PCB fault
(Lock Fail)
Water Leakage
Error
- The air hose is out of place and water leakage occurs
during the spin cycle.
- Water leakage occurs at the front with foaming
because of too much detergent.
- Water leakage occurs because the connecting hose
to the detergent drawer is connected incorrectly.
Overflow Error
- Water is supplied continually because the water level
detection does not work.
- Because the drain hose is clogged and there is
an injection error (at a narrow section), the water
level detection does not work and water is supplied
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.
(Contact error, temperature sensor fault)
- 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
- As laundry causes this error, check the laundry.
- 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.
When the removal is finished, the normal cycle
proceeds. “Sd” or “SUd” is displayed when too much
foaming is detected and “End” (WA456*) / “En”
(WA422*,WA400*)
is displayed when the removal of
the foaming is finished.
(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
under 0.5V and it continues for 5 seconds, this error
occurs.
1. Check the MEMS sensor and PBA.
2. Check the wire connector terminals.
