Re: hotpoint wm73 still getting same error
timdowning is correct, E15 is often caused by a heater earth fault. It can be caused by the drum catching on the heater and wearing through the element outer casing.
Drum support or bearing failure can cause this, is the machine noisy on spin when fully loaded?
If you do remove the heating element and it does show signs of damage about two inches in from the front then you have almost certainly got a drum support/bearing problem.
