- The washing heater is short-circuited or has a wire
disconnected.
- The washing heater in the tub has an Check.
(Contact Check, temperature sensor fault)
- If the water level sensor operates without water because 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.
- The drying heater is short-circuited or has a wire disconnected.
- Heater engagement fault. (out of place)
- The air hose is out of place and water leakage occurs during
the spin cycle.
- The tub back at the safety bolts fixing part is broken.
- 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.
- The drain pump filter cover is engaged incorrectly.
- Water leakage occurs at the drain hose.
- The duct condensing holding screws are worn.
- The nozzle-diaphragm is engaged in the opposite direction or
the rubber packaging is omitted.
- Water leakage occurs because the screws that hold the tub
back and front in place are fastened incorrectly.
- The leakage sensor is faulty.
- Water is supplied continually because the water level detection
does not work.
- Because the drain hose is clogged and there is an injection
Check (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 Check may occur when the water level sensor is
degraded.
- The washing heater sensor in the tub has an Check.
(Contact Check or 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.
- IPM temperature is abnormally high.
- As laundry causes this Check, check the laundry.
- Find the reason for the unbalance and solve it as directed in
the user manual.
- 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.
"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 Check for
preventing non-sensing faults.)
- Check the Wire Connections if there is External Mems PBA
Replace If necessary
1. Replace the Mems PBA
2. Replace the Main PBA
Causes Remarks
If the heater has no
Check, this occurs
because of a PBA relay
malfunction.
This Check occurs
because the water
level sensor terminal is
out of place.
