The dishwasher works but the timer goes to 1 and stays till you turn off. Replaced the control module and still goes to 1 and stays. Upon running diagnostics I get a 3 which is aqua sensor and heating fault. Water did seem to get hot though and sometimes the tablet would not fall out.
You will need to check under the unit and check to make sure that there is no water in the base plate. If there is then this would be the cause. If water is in the baseplate then the flood switch is seeing this and causing the drain to continue to run until the water is sensed not being there.
I have a Bosch model 8806.
At first I would find the deterent tablet on the bottom of dishwasher never dissoved. Now the dishwasher doesn't even start when you turn it on.
What is the problem?
You will want to check to make sure that there is power getting to the control board. If the Control board has power going into it and the door switches are good then you would need a new control unit.
