6) Pulsator doesn't rotate normally.
Where, what & how to check?
4. Pulsator weakly rotates.
1) Check voltage at the power outlet where
the washer is plugged into.
2) Check capacitance of the capacitor.
7) Water does not drain.
Where, what & how to check?
Drain Pump
1. Check whether there is drain pump
working sound.
2. Check resistance between terminals if
there is no working sound of the drain
pump.
3. Check connection parts of the leads if
there is no working sound and its
resistance is normal.
Drain Hose
1. Check whether the drain hose is put in a
narrow space and kinked.
2. Check whether the drain hose is
blocked by foreign objects. It may
happen in case of the hose is a little
kinked.
Result of Check
