5.6. Washing Pump
5.6.1. Possible cause of Malfunction
1. The motor coil is broken, so the wash pump can’t work. It will cause E3 error.
2. The motor rotor capacitor is weaken, so washing pump can’t start. In this case, it will send out the electromagnetism noise. If
it is continue electrifying motor, the thermal protector will work. It will cause E3 error.
3. The connector is loose, the wash pump can’t work. It will cause E3 error.
4. The rotor is locked by residues, so the wash pump can’t work. It will cause the E3 error.
5. The drain pump assembly bracket is loose, it will cause noise.
6. If the machine hasn’t been used for long time, there is a possibility the wash pump can’t starting.
