Hi All,
I need help fault finding for my Electrolux front loader washing machine model EWF1074.
What led to the issue:
The drain was blocked therefore the washing machine could not drain out all the water. Then with the washing machine half full of water someone ran the spin cycle.
What it does now:
Now when you run a new cycle the washing machine just runs the water through the prewash valve and the pump pumps the water out the waste hose.
What I have tested:
- Front pump 225 Ohms
- Back pump 186 Ohms
- Both the prewash and main water inlet valve have 3.6k Ohms.
On the PCB, I've tested the following (I didn't remove any components to test though):
- Green resistor R93: 47 Ohms
- Red inductor L1: 0.2 Ohms (might need replacing?)
- R94 diode: 0.5 volts
- D6 diode: 0.5 volts
- Transformer E47 x 1304: 8 Ohms on one side, 0.02 Ohms on the other side.
It seems like people change out the power integration but I don't know how to test that.
Do you have any ideas of what I should check/test? Thank you.
