Washer water overflow.

i am a recently retired engineer of 20 years and this sounds like a blockage to start with,
when you remove the lid you will find a round disc like object (pressure switch) with a thin pipe coming from it going down to the bottom end of the machine, this pipe as either come off or is blocked somewhere.
drain the machine totally, clear out the pipes, make sure there are no damaged parts to the pipes, then make sure all are fitted properly, start the machine off again and watch for water level shutting off near the bottom of the door,

start with the above, if this doesn't cover the fault there may be an issue with the timer or electrical fault elsewhere/?
hope this helps, if so rate me please, thank you

Thanks, you saved me $23 and headach. Much appreciated.
