Whirlpool Dishwasher Not Draining
If your Whirlpool dishwasher leaves dirty water pooled in the tub, the cause is almost always a clogged filter, a blocked garbage-disposal knockout plug, or a kinked drain hose — rarely a failed pump. Start with the filter.
F8 E1
Means: Drain fault — the dishwasher didn't pump out water in the expected time.
Fix: Clean the filter and check the drain hose and disposal knockout plug.
Why a Whirlpool dishwasher won't drain
- Clogged filter: food debris in the cylindrical filter at the tub bottom — the #1 cause.
- Disposal knockout plug left in: a new garbage disposal ships with a plug that must be removed for the dishwasher to drain.
- Kinked or clogged drain hose: bent behind the cabinet or clogged with grease.
- Blocked air gap: the countertop air gap can fill with debris.
Fix it in 6 steps
- Turn the dishwasher off and scoop out standing water with a cup and sponge.
- Twist out the filter at the tub bottom, rinse it, and clear the sump.
- Check the drain hose under the sink for kinks.
- If newly installed with a disposal, remove the disposal knockout plug.
- Clean the countertop air gap if present.
- Run a rinse cycle to confirm it drains.

FAQ
Why is there water in the bottom of my Whirlpool dishwasher?
A small amount is normal; a full pool means it's not draining — usually a clogged filter, a kinked drain hose, or a disposal knockout plug left in place.
Do I need to remove a plug for a new disposal?
Yes. New garbage disposals ship with a knockout plug in the dishwasher drain port; if it isn't removed the dishwasher can't drain.
