Hi, I'm trying to fix a Bosch 4803 dishwasher. I've unscrewed
everything I can see, and I can't separate the bottom/tub from the
upper part. I need to get into the guts of the thing to replace (I
think) the flow switch and/or NTC.

The symptoms a the water doesn't heat and the cycle doesn't end, and
then it doesn't drain. I managed to get a wiring diagram from the
company, but I'm unable so far to take it apart.

Any hints?
thanks
michael
