Whirlpool Dishwasher Not Draining at End of Cycle? This May be the Problem…


Dirty dishwater and clean dishes just don’t go together. So if you have a Whirlpool dishwasher not draining at end of cycle, you need to know why. With a few simple troubleshooting steps, you can determine if your dishwasher needs some TLC or more serious repair.

Causes of a Whirlpool Dishwasher Not Draining at End of Cycle

Drain Pump Isn’t Working

You could have a Whirlpool dishwasher drain pump not working if you have standing water in your dishwasher. The drain pump uses an impeller to shoot water through the drain hose. If the pump fails, that water’s not going anywhere.

Check the pump for continuity using a multimeter to determine if it is working properly. If there is no continuity, or if the power is fine but it still won’t work, then it needs to be replaced.

Without a functioning drain pump, you will continue to have a Whirlpool dishwasher not draining at end of cycle.

Drain Impeller is Broken

If you have a Whirlpool dishwasher not draining at end of cycle and the drain pump is not to blame, the drain impeller could be broken. The impeller forces water through the drain hose. If the impeller is broken, the dirty water will remain in the bottom of the dishwasher.

If the drain impeller is broken, replace the impeller.

Drain Valve is Clogged

A common reason why a dishwasher doesn’t drain is a clogged drain valve. When we use our dishwasher, especially if we don’t always scrape food particles off, the debris gets left behind and eventually begins to accumulate around the drain valve. Once the drain valve is clogged with debris, the dishwater can’t filter through the valve and out through the drain hose.

The best way to boost dishwasher performance and make sure the dishwater can flow out through the drain hose is to keep the drain valve clean.

Completely clear out all debris from the drain valve. If the drain valve is free of debris and still won’t actuate, then it’s probably defective. Drain valves are not repairable, if it is defective, replace it.

Garbage Disposal is clogged

A clogged garbage disposal is an all too common cause for a Whirlpool dishwasher not draining at end of cycle, We see this a lot around the holidays when people hastily throw scraps into the disposal that should be thrown in the garbage. Don’t let this be you!

If your dishwasher has standing water after cycle completion and you suspect the disposal is clogged, there is hope! Make sure the disposal is off and clear out any debris in the disposal opening in the sink.

Under the sink, unplug the disposal and use an Allen wrench to manually turn and break up the debris inside the disposal. This will usually loosen things up enough to get them moving again. You may also need to disconnect the drain hose and clean out the fittings on the end of the hose and the disposer.
