Technical data
The work principle
Washing pump is a kind of asynchronism
motor with capacitor. The stator consist of
silicon steel stack and two coils, main coil and
assistant coil .
The defeat point
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.
