Overfill problem on Bosch dishwasher
« on: March 13, 2018, 08:53:15 AM »

Still having an overfill problem on this model#63012923313 Bosch dishwasher. After replacing main control board unit working
okay for couple cycles ,then back to filling, water stopping & then beeping. Looking in bottom(without removing base) I don,t see
an overfill  sensor or anything. Drain hose under sink doesn,t have a loop but drain port for dishwasher is above the trap.Even though
it has the air break could unit still syphon? Water in drain hose is quite close to port on house plumbing when unit is done pumping out

On some Bosch models, the overfill sensor is built in to the case brake. It looks like a small float at the top to the case brake. I had two of them doing the same thing, and the float was stuck.

Hi
    This model has no sensor on or in case break.Theres like a float for drain loop in case break but nothing with
electrical wires. Case break was replaced.I can,t figure out why unit worked a few times after main control board
was replaced.Is there any sensors on what they call heat pumps? I,ve never come across heat pump problems.
Even on wiring diagram I couldn,t spot an over fill sensor or anything  in fill circuit.
