Dishwasher not cleaning dishes or dissolving tablet. Bosch repairman turned on the unit, after 30 seconds opened it up and said water will spray out. It didn't so he concluded that there is not enough water pressure and there's nothing I can do. I told him it's the same feed from the sink and that has enough pressure and I had several dishwashers before that worked fine.
I though the unit fills up a little and the unit has a pump built it that creates pressure to the upper arm. Am I wrong?
