Check the electric part
1.Open the control panel and take out PCB(see the section"Part Name PCB");
2.With the door closed, unplug the CON1 and
CON2, then use the multi-meter Ω shelf to test
resistance between two wires (ML-H and ACN),
the normal resistance is about 100Ω to 130Ω.
Αnd test resistance between two wires
(ML-H and ML-L), the normal resistance is
about 35Ω to 45Ω.
3.If any of the resistances is not correct, it means
the pump coil is broken or the connector is loose,
In this case, we should check the connection first.
If the problem hasn't been solved by re-connection,
we would replace the washing pump.
4.If the resistance is OK but it cannot work, it maybe the
capacitor weakly, we need to replace the capacitor.
Check the machine part
1. If the electric part is OK, we need to check the machine part.
2. Remove bottom board.
3. Check the pump assembly, if the bracket is loose, it will bring the noise, we need to
tighten it.
4. If the wash pump cannot start and the machine hasn't been used too long, maybe the
seal element is bond.
5. If the drain pump is working, but no water out or just a little. We should check the vane
wheel.
Washing Pump
The softener is designed to remove minerals and salts from the water, which would
have a detrimental or adverse effect on the operation of the appliance.
