Description of Photo
Temperature
Sensor
tC1
tC2
tC3
tC4
• Washing temperature sensor
fault
• Dry temperature sensor fault
• Faulty and incorrect
connections of the dry
condensing sensor
• Main PCB fault
• Freezing in the winter season
• IPM temperature is abnormally
high.
• Check the connections for the
washing heater temperature
sensor connector.
• If the washing heater
temperature sensor has a
functional error, replace it.
- A tC1 error occurs.
• Check the connections for the
dry heater temperature sensor
connector.
• If the dry heater temperature
sensor has a functional error,
replace it.
- A tC2 error occurs.
-
Foaming
Detected
Sud
• Too much foaming
• It is also displayed while foaming
is removed.
- When the removal is finished,
the normal cycle proceeds.
“Sud” or “SUdS” is displayed
when too much foaming is
detected and “End” is displayed
when the removal of the
foaming is finished.
(This is one of the normal
operations. It is an operation for
preventing non-sensing faults.)
-
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.
-
Unbalance
UB
• Caused by the laundry.
Check the type of laundry.
The laundry load is unbalanced.
Redistribute the load.
Washing one item i.e. blanket, pillow
or a large towel can cause weight
shift during the spin cycle.
-
Add Door
DDC/
ddC
• Add Door Open/Close switch
fault
• Main PCB fault
Check the Add Door. The Add Door
is opened. Close the Add Door and
press Start button.
If the Add Door in not opened, need
to check assembly of wire harness
and PBA.
-
DC3
• Add Door Lock switch fault
• Main PCB fault
Check the Add Door Lock. The Add
Door is not locked. If Add Door Lock
could not operate, change the Add
Door Lock.
If the Add Door Lock operates well,
need to check assembly of wire
harness and PBA.
-
Auto Dispense
6C1
• The input arrest of the
detergent motor is sensed.
Check the wire and if necessary
replace it.
1. Check Wire connection.
2. Replace Assy Pump.
6C2
• The non-operation of the
detergent motor is sensed.
6C3
• The input arrest of the fabric
softener motor
6C4
• The non operation of the fabric
softener motor is sensed.
6C5
• The motor motion perception
sensor fault
6C6
• The detergent level
perception sensor fault
6C7
• The fabric softener level
perception sensor fault
