Re: flashing door lock light on a hotpoint wma44p
It is a strong possiblity that the arcing brushes, particularly Bosch motor brushes have blown the main PCB. It is often possible to see signs of blown tracks or components on the board. If the replacement brushes came without black plastic holders and slotted into the side of the motor then that is a Bosch motor.
Also the wiring harness to the motor can chafe badly on the lower concrete balance weight.
