Bosch dishwasher does not drain water and does not run

One of the reasons for motor not draining during normal cycle is the check valve is stuck. It is meant to return to normal during drain cycle but close during wash. I think the cancel is resetting it and letting water out.

Certainly *sounds* like the float is stuck in the over filled position
or possible a bad float switch, if the float is stuck in the up or full position, the d/w will not fill with water and the drain motor will often run all the time

Drain hose clogs commonly occurwhere the hose is attached to the main household drain line, or where the hoseconnects with the garbage disposer. Turn mainswater off and disconnect mains power Tryremoving the drain hose to unclog any debris. Don't forget to reattach the hosebefore you start your dishwasher again.The drainpump is blocked or restricted by debrisPossibly something stuck/jammed in the wash or drainpropeller, remove filter mesh at the bottom of the dishwasher.

If you take the kick plate off from below the door youshould be able to access the base to remove any excess water.Behind your kick board is a plate below the door. Remove theplate.
With the power off push a rag into the base plate to soak up the water.
Failing that pull out the dishwasher onto the floor and tilt the machine backto allow the water to run outSwitch the water and power back on and restart the programto test.If the appliance is less than 2 years old Neff/Bosch Groupguarantees it

Is there no water coming in( hear no water at all) or no water NOT staying in ( drain motor running) ... the float switch is a safety to keep the dishwasher from flooding ...turns on the drain motor as soon as the door is closed..

I could check the control and see if you have power to the water valve.. maybe a control problem if no power..

float switch is in the flood position and the drain pump is running.. there is water under the dishwasher or that switch is stuck up..

My Bosch SHU43C had the same exact problem. I found the below solution on this site. Perhaps you already seen it.

My SHU43C is just over 3 years old. I had a similar problem recently. First, there were a few floods. Then, the Bosch only drained non-stop. Even when I used the Cancel Drain buttons the drain pump would run without stopping. When I tried to run one of the cleaning cycles, no water entered the machine. Corrective: I removed the base plate, and saw that the red plastic floatation device was in the up position. Using a flashlight and a wooden spoon, I lightly toggled the red float stem down. I pushed regular clean cycle and kept toggling with the red float stem until the rinse water started to enter the machine (turning the red stem seems to also actuate a step in the program). Now the dishwasher runs normally. Voila!

what is the model #?... there are 2 buttons when pushed together it will drain the water out..try the button to the left next to power scrub... and economy...hold the 2 buttons for 3 sec. you will hear you drain pump running.. if you don't hear any water draining out into your sink, you might have a clog d/w drain line.
