Frigidaire Washer Drain Pump Replacement Guide — Cost, Signs & DIY Tips

The Frigidaire EFLS front-load washer drain pump (commonly part# 137221600) sits behind the lower-left access door at the front of the machine. Frigidaire front-loaders have a user-accessible drain pump filter (coin trap) — a twist-cap that allows you to clear debris from the pump inlet without disassembling anything. This filter is the first thing to check when the washer displays an E21 drain error.

Top-load washers (FFTW) have a drain pump accessed from the bottom (tilt the machine back).

The Coin Trap Filter — Check This First

Before replacing the drain pump, clean the coin trap filter. This 5-minute task resolves E21 errors more than half the time.

1. Place towels on the floor and a shallow pan against the washer front
2. Open the small access door at the lower-left front
3. Pull the small drain hose out (if equipped) and drain residual water into the pan
4. Twist the round filter cap counterclockwise and pull it out
5. Remove any debris — coins, buttons, hair ties, underwire bra pieces, pocket lint balls
6. Clean the filter screen under running water
7. Reinstall the cap (clockwise until snug — do not overtighten) and close the access door

If the E21 error returns after cleaning the filter, the pump itself may be failing.

Symptoms of Drain Pump Failure

• E21 error code — the most common Frigidaire washer error. The board commanded a drain but water level did not drop sufficiently within the expected time
• Water remains in the drum after the cycle — you open the door and the drum is still full. The pump is not evacuating
• Grinding or rattling noise during drain — debris past the filter has reached the impeller, or the impeller vanes are cracked
• Pump hums but no water moves — the motor runs (you hear it) but the impeller is seized or separated from the shaft
• Slow drain — the pump works but takes much longer than normal. Partial impeller obstruction or worn impeller vanes

Drain Pump Cost

Replacement (EFLS Front-Load)

1. Unplug the washer.
2. Remove the lower front panel (1 screw each side, or snap clips). The drain pump is visible at the lower-left.
3. Drain residual water via the coin trap filter hose or by placing towels and removing the filter cap.
4. Disconnect the pump wire connector (2-pin Molex).
5. Release the hose clamps on the inlet and outlet hoses (spring clamps — channel-lock pliers).
6. Remove the pump mounting screws (2–3 Phillips or hex screws).
7. Install the new pump. Mount with screws, reconnect hoses with clamps positioned over barb ridges, reconnect wire connector.
8. Reinstall the coin trap filter and lower front panel.
9. Plug in. Run a rinse & spin cycle to verify drain function.

Tools: Phillips #2, channel-lock pliers, towels. Time: 25–40 minutes.

E21 Error Troubleshooting Tree

1. Clean coin trap filter → run cycle → still E21?
2. Check drain hose for kinks or clogs → still E21?
3. Check standpipe height (drain hose must enter the standpipe at 24–36 inches above floor) → still E21?
4. Listen for pump noise during drain — humming but no drainage = jammed impeller or failed pump
5. No pump noise at all = dead pump motor or failed board output (test for voltage at pump connector during drain attempt)

Perfect Balance Suspension Note

When replacing the drain pump, you have access to the front shock absorbers (part of Frigidaire's Perfect Balance anti-vibration system). If the washer has been vibrating excessively, inspect the front shocks — they are directly accessible with the lower panel removed. The absorbers (part# 5304485917, sold in pairs) degrade over time and cause shaking during spin.

FAQ

What does E21 mean on my Frigidaire washer?

Drain error — water did not evacuate in time. Clean the coin trap filter first (lower-left access door). This resolves the issue over 50% of the time.

Where is the Frigidaire washer drain pump filter?

Behind the small access door at the lower-left front of EFLS front-load washers. Twist the cap counterclockwise to open.

Can I clean the drain pump instead of replacing it?

You can clear debris from the impeller via the coin trap opening. But if the impeller is cracked, motor is burned, or bearings are seized — replace the pump.

How often should I clean the coin trap filter?

Monthly. This prevents E21 errors and prolongs pump life. Also check for missing items (coins, jewelry) after each laundry load.
