I have a Bosch dishwasher shy66c06us. The washer comes on and I have noticed the following:
does not wash the items
There is water in the botton of the machine.
when I open it during mid-cycle water is only coming slowly out of the botton sprayer. I try to use only the top tray, but no water make it to the top.
I check the bottom of the machine and it is clean(I did what you recommended).
So I try the dishwasher again. This is what happen
the first time the machine let the water out, but nothing is clean.
I try it one more time, this time, it did not let the water out, and the items are still not washed, also the soap in not used(the soap dispensor is open).
Sounds like there are problems with the circulation and the drain pumps. The dishwasher has to be removed from the cabinet for more exact diagnosis an/or repair.
