these are so easy to sort as a rule???
do you see the water going up and up above the door glass then start to pour out?.As the pressure increases it gets to a level and then switches water off.If however the pressure drops it will try to refill until the pressure is back to the cutoff point.pull the black pressure hose off and suck air out with your finger on the other end.now see if it holds a vacuum for a good length of time using your tongue as a stopper if that makes sense.Taking the pressure switch apart might not of done it any favours and if that is leaking will cause your problem.NEVER in all my time have I had an issue with the timer causing an overfilling situation on this model machine.blocked vent tubes on top of the tub also cause water to pour out soap draw
