Electrolux Washer E21 Error Code: Drain Timeout

Quick Answer

The Electrolux E21 error code means the washer could not drain in time. Clean the drain pump filter first - this is the access panel at the bottom-left of the front panel and takes 5 minutes. Clogged pump filters cause 45% of E21 faults with no parts needed.

Clogged pump filters cause 45% of E21 faults with no parts needed. Also check the drain hose for kinks and make sure the drain hose standpipe is not lower than 24 inches from the floor (too low creates a siphon). If cleaning and hose check do not fix it, test the drain pump motor resistance.

Frequently Asked Questions

How often should I clean the Electrolux drain pump filter?

Every 3-6 months under normal use, or more frequently if you wash items with lots of lint (towels, pet bedding). The filter is designed to catch lint, coins, and small objects before they reach the pump impeller. A 5-minute cleaning every few months prevents most E21 faults.

My Electrolux washer shows E21 but drains slowly, not completely. Is the pump failing?

Slow draining that does not fully empty the drum points to a partially clogged filter or hose restriction before it becomes a full pump failure. Clean the filter and check the drain hose routing first. A failing pump typically stops entirely rather than draining slowly.

Can using too much detergent cause E21?

Excessive suds can slow the drain pump by reducing the pump's ability to move water efficiently - foam does not pump like water. Use only HE detergent in the amount specified on the label. If you see foam inside the drum when starting a new cycle, use less detergent.

Where is the drain filter on an Electrolux EFLS washer?

The drain filter is behind a small rectangular access panel at the bottom-left of the front panel. Pop the panel open (it may have a snap clip or small Phillips screw), and the filter cap is visible inside. Turn the cap counterclockwise to remove it - have towels ready.

The drain pump hums but water does not pump out. What is wrong?

A pump that hums but does not move water has a blocked impeller - something is jammed between the impeller fins. Remove the drain filter and reach into the pump housing to feel for a coin, underwire, or other foreign object blocking the spinning impeller.
