The E21 error code on a front-load
washing machine indicates a rainage
issue. This means the machine is not
draining water properly during the wash
cycle.
Common Causes of E21 Error (Possible Issues)
Clogged Drain Hose: A blockage in
the drain hose can prevent water
from flowing out.
Faulty Drain Pump: If the pump is
malfunctioning, it won't be able to
expel water.
Bad Wiring Connections: Loose or
damaged wiring can disrupt the
pump's operation.
Improper Installation: Incorrect
installation can affect drainage
Defective Control Board: A
malfunctioning control board may
not send the correct signals to the
pump.
Troubleshooting Steps (Step-by-Step Guide)
1. Check Installation: Ensure the
washer is level and the drain hose is
correctly positioned. The hose
should not extend more than 10 cm
into the drain.
2. Inspect the Drain Hose: Look for
kinks, clogs, or restrictions. Remove
the hose and flush it with water to
clear any debris.
3. Examine the Drain Pump: Listen for
unusual noises during the drain
cycle. If the pump is silent or making
loud sounds, it may be jammed or
faulty.
Test Pump Voltage: If the pump is
humming but not working, check
the electrical supply to ensure it is
receiving power.
5. Reset the Machine: Unplug the
washer for about 5 minutes to reset
the control panel, which can
sometimes resolve the issue.
If these steps do not resolve the E21 error,
it may be necessary to contact a service
technician for further assistance.
