About five seconds after you start running a dishwasher cycle, the drain pump will start making a low humming noise. This will be due to a piece of glass blocking the impeller from turning, resulting in the dishwasher pump not working properly. When this happens, you'll need to remove the blockage.

The most common reasons your Frigidaire dishwasher has no water are a broken detergent dispenser, defective electronic control board or a clogged water valve.

The drain hose can also sometimes become kinked or obstructed, preventing the water from draining out. Inspecting the hose for bends or clogs and removing any obstructions can resolve this issue. The pump helps expel the water from the dishwasher. If it malfunctions or gets blocked, the water won't drain.

Some dishwashers come equipped with a reset button on the control panel. If your model has one, locate the button and press it. Hold the button for a few seconds until you see lights blink or hear a beep. This action should initiate the reset process.

How do I force my dishwasher to drain? You can typically activate your dishwasher's drainage function by holding the cancel button for around three seconds or the time indicated on your model. Once the dishwasher stops running, the water should drain if it's working correctly.

Why is there water left in the bottom of my dishwasher? ›

Occasionally, a dishwasher may have standing water remaining if the cycle has been interrupted before the draining process has been completed. Excessive standing water that fills the bottom of your dishwasher after a complete wash cycle is likely due to a clog in the drain or nearby garbage disposal.

Since it is common for debris to get stuck in the dishwasher drain, try cleaning it with a solution of equal parts baking soda and vinegar. Pour the baking soda and vinegar into the bottom of the dishwasher and let it sit for 15 minutes. Then run a rinse cycle at the highest heat setting.

Many control boards cost $250 to as much as $1100 while UpFix repair service only costs $119.00. Shipping charges are typically a wash. From a cost standpoint repairing is oftentimes a no-brainer.

Frigidaire Dishwasher Control Panel

If lights are illuminated or some of the control works, it's likely the control panel is faulty and will need to be replaced. If no lights and no functionality is present, it's more likely a line fuse or main control board is at fault.
