OVER FLOW
OC
OF
- 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 may occur when the water level sensor is
degraded.
• Water level sensor fault
• Freezing by winter season
13
Temperature
Sensor
TC1
- The washing heater in the tub has an error. (Contact
error, temperature sensor fault)
- The connector is connected incorrectly or is
disconnected.
- If the water level sensor operates without water
because the water is frozen or for any other reason
and the temperature sensor engaged at the bottom to
prevent overheating for the washing heater detects a
temperature of 100 to 150 ˚C, the washing machine
turns the input power off.
• Washing temperature sensor
check
• Dry temperature sensor check
• Dry condensing temperature
sensor check
• Problems caused by the main
PCB fault
• Problems caused by the freezing
in winter
TC2
- The temperature sensor for the duct assy fan housing
is faulty. (A sensor fault such as an internal short-
circuit or wire disconnection)
- The connector is out of place or has a contact error.
TC3
- Occur Duct condensing temperature sensor when is
OPEN
- This occurs when the duct condensing temperature
sensor has a wire disconnected or is short-circuited.
14
UNBALANCE
Ub
- As laundry causes this error, check the laundry.
- Find the reason for the unbalance and solve it as
directed in the user manual.
• This occurs by laundry.
15
Power
UC
(9C)
- Power condition fault.
- An error occurs when under or over voltage is
supplied.
- Plug receptacle is used
- Main PBA fault (sometimes)
• Check the consumer’s power
conditions. : Make sure to check
the operating voltage.
• Connect a tester to the internal
power terminals during the Boil
or Dry operations and observe
the washing machine’s operation
carefully.
: Check the voltages.
(An error occurs when under or
over voltage is supplied.)
: Check whether a plug receptacle
is used. When the connecting wire
is 1m, a momentary low voltage
may drop up to 10 V.
• Main PBA fault (sometimes)
16
Mems PBA
8C
- Error detected in the Mems PBA or data error detected
• Check the wire connections.
Replace if necessary.
1. Check the wire connections.
2. Replace the Mems PBA.
3. Main PBA wire connection
error or PBA’s silver nano
part malfunction. Replace if
necessary.
