Frigidaire Washer Error Code E21: How to Fix It

Q: Can I run my Frigidaire washer with error E21?

No. Running the washer with error E21 can cause water to back up and potentially overflow. The machine will not proceed with the cycle until the drain issue is fixed. Always resolve the error before using the washer.

Q: Is error code E21 the same as E20 on Frigidaire washers?

Yes, E20 and E21 are similar drain-related errors. E20 usually indicates a slow drain, while E21 points to a drain pump fault. The troubleshooting steps are nearly identical; both require checking the filter, hose, and pump.

Q: How much does it cost to fix a Frigidaire washer error E21?

If you do it yourself, a replacement drain pump costs $20–$50. If you hire a technician, expect $150–$300 for labor and parts.

Q: Why does my Frigidaire washer keep showing E21 after cleaning the filter?

The error may persist if there's a clog deeper in the drain system, the drain pump itself is faulty, or the control board is misreading the pump signal. Check the hose, pump continuity, and consider resetting the washer by unplugging it for 10 minutes.

Q: Can a clogged vent cause error E21 on a Frigidaire washer?

No. Error E21 is specific to the drain pump circuit. A clogged vent (for a standpipe) could cause slow draining, but it typically results in a different error code (like E20) or a draining issue without an error. Focus on the pump and hose first.

Abstract

Error code E21 on your Frigidaire washer means the machine detects a drain pump fault, usually because the water isn't draining properly. This is often caused by a clogged pump filter, a kinked drain hose, or a faulty drain pump. Most cases can be resolved at home with basic tools.
