Re: drain pump and no water going in

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 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 !

Motor runs with door open. No water in pan.

Sounds to me like there may be water in the moisture sensor. Your dishwasher is probably leaking and the noise you hear is the drain pump activated.

How do I over ride power button, force shut down

The dishwasher has detected a leak, and is trying to drain all the water out of the dishwasher. The problem is that the water has leaked into the base of the dishwasher, and the drain pump doesn't drain water from there! You dishwasher probably has a 1 or 2 lights on (or flashing), which also, when decoded, would indicate a leak. Basically, you have to pull the dishwasher out and sop up and dry up all the water in the base. That will stop the drain pump from running, but you still have the problem of figuring out where the leak came from and fixing the problem before you can use the dishwasher. The most common source of leakage in a Samsung DW is the drain pump and/or drain hose. Good luck! If this sounds like more work that you feel qualified to do, I recommend you call a professional repairman. For Samsung dishwashers, I recommend calling Sears.

Pump continually running with F2 displayed.

There is water in the lower pan that you must access by removing the toe kick plate and then the panel behind it. you will see water in the overflow area. Clean that out and all will be well. Asko's are awesome dishwashers that capture any water they may overflow or leak internally instead of it going on your floor, then a float switch triggers the F2 error and runs the drain pump.

Water not draning

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.

Bosch SHU runs even when the door is open, what do i need?

Hi Jeffrey,

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.

Regards, BElectric

Won't drain

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!

What is causing the drain pump to continue running

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.

Pump running non stop.

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!
