Re: whirlpool awo/d 4505 service light coming on/violent sha
The machine should fill, then start to tumble gently. If it fills then starts banging about violently, the motor will be running without speed control. This could be down to the tacho (feedback) circuit in the motor; broken wiring (common) or a pcb problem.
If it only does it on the spin sequence, I’d be looking for a blockage.
Power off if you intend to work on the machine yourself.
