hi could anyone help me with this, dont generally do dishwashers so not too familiar, this dishwasher sometimes leaks, it seems to overfill ,took front panel off and the front bottom seal is perished at one side so when its running i can see the level getting higher then i guess the safety overfill cuts in then the level drops and this keeps repeating… question is does it have a pressure switch and is this like a washer set up and where is it 😕 ..thanks
