This most likely is not a level switch problem. Take the kick plate off (after turning circuit breaker OFF), look down in the base off the dw and youll probably see some water. Use a wet vac or towel to remove all water. The drain pump will now shut off and unit should function normally. You can now run the dw with the kick plate off and using a flashlight look for leaks. The bosch dw has a float switch in the base, water will activate this switch which will shut off the water valve and only allow the drain pump to run....it thinks it has a leak!
Make sure the disposal is draining properly & drain hose is not kinked as these are the most common reasons for your problem.

Re: drain pump and no water going in
It sound as a water level switch issue.The switch level is usually a diaphragm device with a small clear tube attached between the switch and the bottom of the washer's outer tub. I am not familiar with this specific machine, but if you will open the service panel you will find it easily. Clear tube first from any obstruction, In case it doesn't help, disconnect the wires from the unit (you should disconnect first machine's power cable !!!!!) and measure with a multi-meter on its tugs for continuity and disconnection while you are inhale and blow to its tube.
In case it doesn't react, you should replace it.
Good luck !

When a unit has an issue draining one of the first things to check on the unit would be to listen if you can hear the sound of the Drain pump activating. If the Drain pump were makeing sound and running then first your would go under the sink area and disconnect the drain line that goes to either the garbage disposal or sink. After disconnecting the drain line you would look inside where the drain line connects to to assure there is no blockage in the port hole area that the water flows. If you do not see a blockage here then you would have no choice but to pull the unit out from under your counter and check the oppisite end of the drain line as well as the drain pump itself. Also there is a float switch located near the water inlet valve that when activated signals the pump to start pumping out the water. It is also sugggested to remove the drain pump if you do not hear it running an take an old extension cord and cut off the female end. After you remove the female end of the extension you would then add two cclip electrical connectors to the extension cord this would make a powered jumper wire. You can then plug one side into the pump and the other side into a outlet which would activate the pump and allows you to visually assure that the impellar is spining.

This depends what you mean by "runs". If the dishwasher continues with a wash cycle - i.e. circulating water - with the door open, the simple answer is that you have a defective door microswitch.
However, I suspect what you perceive to be the dishwasher running, is actually the drain pump running continuously. This happens when the anti-flood protection system has been activated and continues even when the door is opened. The simplest way to check is to open the door (while it's "running") and pour some water into the tub. If the water drains away immediately, this shows the drain pump is running and the anti-flood protection has been activated.
This may be due to water having leaked into the base of the dishwasher, but it could be as simple as a stuck or defective float-switch.
Please try the simple test above then post back for further assistance. If you're planning to investigate or repair this yourself, you're going to need a Torx T20 screwdriver and a multi-meter would be useful as well.
Sounds like there is a problem with the drain. But I suspect there is also some water in the tray under the dishwasher. There is a float switch in the tray which will run the drain pump. I usually use a shopvac to clear the water from the tray. Check the pump impeller by putting you finger into the pump from inside the dishwasher. It is on the right side under the screens. If the impeller is loose then it could be a bad pump. If you have recently replaced your disposal, make sure the plug is removed where the dishwasher drains into it. You would be surprised how often this is forgotten! Hope this helps, feel free to ask if there is anything else!
C1 - Partially Blocked Drain - This error will occur when dishwasher was unable to pump out water in less than 95 seconds. Check drain line for debris and blockage. If clear, check for a restricted drain valve in the pump. Check the pressure sensor for correct operation as it sounds like it may be defective and thinks that the machine is still full of water after it has emptied.
On the left hand side of the dishwasher (looking from the front, open door) there is the water inlet port. Behind it is a float assembly that determines how much water is in the dishwasher and how much it needs to add or pump out.
If you pull the outside, panel, you will see that float assembly. Check for loose connection. Since you are getting no error codes, if everything looks OK, I recommend either schedule a service call or replace that assembly. If problems continue, the main controller board (PCB) is the next most probable cause.
Please report back with what you find. Thanks!
There is a recall on the control board of many of these models, butyour problem is likely not related. It sounds like a plugged drain system or a possible bad drain pump. That's why you are hearing the pump running constantly. I have written a guide to help. It is here. Thanks!
