No fill - drain pump running - I assume stuck float switch

Is the float intact? Sounds like it got swamped. Try floating it with thin piece of styrofoam underneath. Run one fill cycle. If that works, replace float or repair it.

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

There is a float under the machine that tells the pump to shut off. If the float is stuck or bad, the machine will keep draining. I am including a web site that might help. Bosch Dishwasher That Will Not Stop Draining Hunker

Sounds like flood switch has been activated. They have a float in the base of machine, which will activate drain pump if a leak has occurred. Unplug from power- remove right hand side panel, check to see if any water in base. If so, leak has occurred. Clear water from base and test run to locate leak

check the base of the dishwasher for water. remove the toe kick at the bottem and soak up the water down there. its probably activating the float switch. im assuming you had a drain problem with the sink? so the dishwasher couldnt properly drain.

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..

Check first the drain lines and the drain pump.

If the drain pump is working, and there is no problem in there, then the problem is usually because the water level switch activated by the floating sensor is stuck.

You probably need to have the water level switch replaced.

there should be a float behind the fill valve with a magnet in it which operates a reed switch. This switch keeps the pump running as long as the base has water in it or if the float is stuck on the up side (and makes the pump "think" that there's water in the base). Check this float to see if it's stuck and release it so it could tell the pump when to stop draining. Hope this solves your problem.
