When I push the on/off button on, the pump tries to drain even though there is no water in bottom of unit. It runs continuously. It is as if the sensor for the water level is telling the pump that there is water but there isn't. It starts without me even hitting one of the wash buttons. Help!!

Hello, If your dishwasher is stuck in the drain cycle there could be two reasons for the unit doing this. The first reason is you could have something clogged in the drain line or blocking the drain pumps impellar. If the unit is not able to empty the water out of the unit the drain pump will continue to try and empty the water. The second reason would be if you had a leak condition in which if you did have a leak the drain pump would continue trying to empty the unit to prevent the unit from leaking water outside of the unit. I would first remove where the drain line connects to your drain and inspect this area first if you do not find any blockages in this area you would have to de-install the unit from under the counter and check the oppisite end of the drain line to where it attaches to the drain pump itself. If you still found no blockages you would then remove and inspect the drain pump assuring that the impellar of the drain pump is spining and that there is nothing clogging the pump as well. If you have any further questions message me back. I await your reply Thank you Rick
Usually in a miele dishwasher when the power does not shut off this is due to a leak condition in which the pump is trying to pump any access water due to a leak out of the unit in which the drain pump of the unit will run continueously to avoid water to come out of the sealed bottom and spill all over your floor. One of the first things that would distinguish if this were the case in your unit, would be if you could hear the drain pump running. This can also happen if you have a clog either in the drain pump or in the drain line or in the port hole where the drain pushes the water into your disposal. If you do not hear the drain pump running. As to the door latch it basicly tells the control that the door is either opened and not to turn on the cycle or closed and then to turn on the cycle and begin to wash. You can also check to assure that you have no leaks by pulling the unit out by deinstalling the unit and removeing the bottom base panel to see if there is any water inside. If you find there is no water and no clogs and you do not hear the drain pump working message me back for further diagnosis. I await your reply. Thank you Rick
The bosch dishwashers use a fill valve that is attatched to the inlet hose. yours is stuck in the open position. this usually happens when you have hard water, as the minerals build up on the sealing surface of the water valve. there is no easy fix. the fill hose will have to be replaced. It requires removing the machine, removing the bottom pan, and changing the hose connections.
the valve uses water pressure to stay closed. if the water pressure is very low coming in, it may not be enough to close the valve. there is a filter screen between the fill hose, and where it connects to your water valve. try cleaning the filter out and see if that makes a difference. If not, you will have to get the hose changed.
Your float may have got stuck or it's possible that you have water leaking into the bottom of the washer. In the bottom of the wash compartment, next to the drain you will find a plastic dome/mushroom (the float). You might need to rotate the bottom spray arm to see it.
Turn the washer on so that the pump starts to run, open the door and push down on the float. This should stop the pump running. When you let go of the float, if it rises back up on its own, then it's almost certain that you have water in the bottom of the washer. If this is the case please post back for further assistance. If the float stays down, then it may have simply got stuck.
Please try this simple test and post back with the results.
This could be that the anti flood device "polystireen float and micro switch at the base has detected water at the bottom due to a leak (pipe or pipe clamp). This device puts the washer in pump out mode and will not continue. Firstly you need to determine what causes the water leak and rectify it before it will continue.
The reason the drain pump continously runs is because it is trying to remove any water too avoid any further flood as there is a flood in the base of the unit which activates the float switch and constantly activates the drain pump until the water has gone. Isolate the unit at the power switch and remove the bottom panel under the door panel. Dry up the water as best possible with a towel. Run the unit again and check for any water leaks. You may just have over sudded the unit with too much detergent. Only use 2 teaspoons of powder. To start with while testing don't use any detergent. Good luck
You most likely have a stubborn clog in your kitchen drain. Try filling the sinks with warm soapy water and then letting the water drain while also turning on your garbage disposal. Sometimes the extra water pressure will help push the clog through.
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!
Intrrnal leak into base of appliance will make drain pump run constantly.
If appliance fills then dumps water with drain punp then keeps filling/draining sequence then the flow meter could de faulty.

is all the water draining from the tub? if not the pressure switch will not reset and it will continue to try and clear it self...check drainage system.
2. pressure switch is jammed on..build up in the sensing chamber..common..or switch faulty...rarely
3. if water is in the bottom panel most have a flood switch which automatically operates the pump in case its over filling
