I have an LG Washing machine that isn’t draining (OE error).
All pipes are clear and I have cleaned the gunk behind the impellers.
Removed impellers (there is 1 on each side of the pump) and tested them by re-connecting to WM power.
Both impellers work off 1 set of leads. They don't work using the other 2 leads.
