Drain pump runs non-stop. Continues when dial is in Stop position. When disconnected for hours, drain pump starts immediately when power restored. In any wash cycle position, drain pump runs and cycle never commences. Small amount of residual water in drain line when impeller cover removed. Board? Switch?

Based on the information you have provided, it seems that your Miele dishwasher is experiencing a drain pump issue, which could be causing the flashing lights and the non-stop running of the pump. Here are a few troubleshooting steps you can try:

1. Turn off the power to the dishwasher: The first step is to turn off the power to the dishwasher by unplugging it or turning off the circuit breaker. Wait for a few minutes and then turn it back on.
2. Check the drain hose: Make sure that the drain hose is not clogged or kinked, as this could prevent the water from draining properly. If you find any blockages, remove them and test the dishwasher again.
3. Clean the filters: Check the dishwasher's filters and make sure they are clean and free of debris. Dirty filters can cause drainage problems.
4. Check the drain pump: If the drain pump is still running non-stop, it may be faulty and need to be replaced. Before you do this, however, make sure that the pump is not clogged with debris. You can do this by removing the pump and inspecting it for blockages.
5. Contact Miele's customer service: If the above steps do not resolve the issue, it may be time to contact Miele's customer service or schedule a service visit to diagnose and repair the problem.

It's important to note that attempting to repair appliances yourself can be dangerous, and you should always follow safety procedures and consult with a professional if you're unsure of how to proceed.

If drain pump is constantly running, its most likely the relay on the pcb, or mechanical timer sticking if older models without pcb.

Check door switch: If the lid switch is bad it will not drain or spin. Try this test: With lid open let it finish wash cycle. Press lid switch down with screwdriver. Washer should begin draining. Release switch. Motor should stop. Press switch a second time. Washer should start spinning as it continues to drain. If motor doesn't come on while lid switch is pressed, replace the switch. OR

Hello.

Frigidaire front-loading washing machines have an electronic control panel where the wash cycle and any other wash options are selected, and the wash cycle is initiated and stopped, if necessary. The control panel also has indicator lights that show the washer status and will display an error code if there are issues with the washer. The "E20" error code indicates a possible pump problem.

Blocked Pump

One of the primary reasons why there may be an "E20" error code on a Frigidaire front-loading washing machine is if there is something blocking the pump. Disconnect the washing machine from the power and release the clips on each side to remove the front access panel. Set a container under the pump drain, which is located on the lower right side of the washing machine. Open the pump drain plug and allow it to drain. Clean out any debris that might be causing the obstruction, then close the drain plug. Close the access panel and restore power to the washer.

Drain Hose

If the drain hose is blocked or crimped, the water may not pump out fast enough, causing the pump error to appear on the display. Straighten out the drain hose in the rear of the washing machine and move it away from the washer if it's trapped between the wall and the washing machine.

Oversudsing

If too much detergent--or the wrong kind of detergent--is used in the washing machine, too many suds may result. This can overwhelm the drain and pump system, resulting in the error. Use only high efficiency (HE) laundry detergent with Frigidaire washing machines and follow specific instructions on the laundry container for the recommended amount of detergent. Run a drain cycle if there are excess suds in the washer to clear out the system.

Pressure Switch or Control Boar

The pressure switch may not be communicating properly with the control board, which can cause the E20 error to occur. The other possibility for the E20 error code is if the control board has failed entirely. Try to reset the washing machine by pressing "Stop/Cancel" and disconnecting the washing machine power cord. Wait 30 seconds, then restore power. Make a new cycle selection and press "Start" to see if the error code returns. If it does, turn off the washing machine and contact Frigidaire for repair.

Thanks.

The top load washer utilizes a pressure switch attached to a clear plastic hose. If the water fills the tub but will not stop filling you will need to remove the top panel and inspect the hose for obstructions. You may need to disconnect the tube flush it clean and make sure no foreign debris are in the connector on the pressure switch. If the tub will over fill, you may need to replace the pressure switch. If the water will not fill the tub and the water continues to run you need to check the drain pump. Is water exiting through the drain hose? If so the drain pump could be the problem.

Check floater valve.

Inside the unit. On the floor. Looks like and small upside down cup.

If it is jammed in the up position it will stop the machine. Lift, clean underneath. It should drop and the machine will run.

The float valve stops the machine from over filling.

Could also be clog in the drain filter. Remove the cover from the drain inside the unit. look for clog in the filer of the drain.

If none of the above it is the timer. The timer tells the unit what to do (fill, run, empty). If it is not working the drain function will not run.

Pump or hoses still blocked,Or pump has had it,Can supply new pump by post if req.

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!

It keeps spinning or you just hear noises and it doesn't end cycle ? Following your description regarding water in tub when you start a new cycle,check for : * Switch level - 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 remove the cabinet, you will find it easily. Clear first any obstruction in the tube,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. * Pump and drain host - Check that pump works and that you have no blockage on your drain line. Good luck !! (courtesy dovi)
