Step-by-Step DIY Fix Guide
- SAFETY: Unplug the washer and keep towels or a shallow tray ready before opening the pump filter area.
- Open the pump-filter or coin-trap access door and drain any trapped water slowly.
- Remove the filter, clear lint, coins, and debris, and rinse the filter thoroughly.
- Check the drain hose behind the washer and confirm it is not kinked or pushed too deep into the standpipe.
- Restore power and run a drain or spin cycle to confirm whether E21 clears.
If E21 comes back after cleaning the filter
- If the filter is clean but the washer still drains slowly, check the household standpipe or sink drain path.
- If the pump runs but water flow is still weak, the impeller or pump path may be worn or obstructed.
- If the washer keeps leaving water after heavy loads, check for recurring lint or small-item buildup.
What This Error Means
Frigidaire washer error E21 means the machine is draining too slowly to continue the cycle normally. The washer still senses water in the tub when it expected the drum to be almost empty.
The first place to check is the pump filter or coin trap on front-load models. Lint, coins, labels, and small fabric items are still the most common cause of E21.
If the filter is clean and the hose path is clear, the next likely issue is a worn drain pump or a restriction farther along the drain route.
Most Likely Cause by Symptom
Water is still in the drum after the cycle should have drained.
Likely cause: The filter or drain path is restricted.
Check first: Open the pump filter area and clear debris first.
The pump runs but draining is very slow.
Likely cause: The pump is pushing against a blockage or worn path.
Check first: Check the filter, hose routing, and standpipe connection before assuming pump failure.
Common Causes
- The pump filter or coin trap is clogged with lint or debris.
- The drain hose is kinked or inserted too deep into the standpipe.
- The household drain path is partly restricted.
- The drain pump impeller is worn or obstructed.
- A small item is trapped deeper in the pump path.
What Not to Do
- Do not keep retrying spin cycles with water still left in the drum.
- Do not assume the pump has failed before checking the filter and hose path first.
Model and Display Variation Notes
Model-family notes
- Frigidaire front-load washers often place the pump filter behind a small lower-front access panel, but the exact layout varies by model family.
- A partial drain fault can still leave the drum only partly full of water, which makes E21 easy to underestimate.
Display and panel differences
- Panel wording can vary by series, so confirm the exact code pattern before buying parts.
Parts, Tools and Service Options
Common parts
- Drain pump assembly ($35–$80)
- Drain hose if permanently kinked ($15–$30)
Manual and model check
Check your exact model before ordering any washer parts.
Service option
Frigidaire service visit if E21 returns after the accessible checks are complete.

When Not to Keep Troubleshooting
E21 returns after the filter and drain hose are checked and cleared.
- The pump runs continuously but draining stays very slow.
- You suspect a worn or blocked drain pump that is no longer user-accessible.
How to Prevent It Recurring
- Clean the pump filter every 3 months — a 5-minute task that prevents the majority of drain faults.
Related Error Codes
E23
The main control board's relay that powers the drain pump has failed. The pump is not receiving the electrical signal to run, so the drum cannot drain. E23 points to an electronic component fault rather than a mechanical blockage.
EF1
The front-load washer's drain pump filter (coin trap) is blocked with lint, debris, or a foreign object. EF1 is one of the most common error codes on front-load Frigidaire and Electrolux washers and is almost always resolved by cleaning the pump filter — a task that takes under 15 minutes.
E13
The front-load washer's pressure sensor has detected water where it should not be — either a leak from the main tub into the base of the machine, or an air leak in the air bell (pressure sensor hose) that is giving false low-water readings. E13 is a high-severity fault that should be investigated promptly.
