Maytag Washer F21 Error — Long Drain Fix

What Does This Error Mean?

Maytag washer F21 error means the drain cycle is taking longer than 8 minutes. Clean the pump filter behind the front access panel — blocked filters cause the majority of F21 errors.

Affected Models

Maytag Front Load Washer
Maytag Maxima Washer
Maytag 2000 Series Washer
Maytag Performance Series Washer

Common Causes

Blocked pump filter — lint, coins, or debris slowing drainage
Kinked or partially blocked drain hose
Drain hose pushed too far into the standpipe creating a siphon
Blocked household drain standpipe
Weak or failing drain pump

How to Fix It

Clean the pump filter.

Open the front access panel at the bottom of the machine. Place a shallow tray underneath. Slowly unscrew the pump filter cap — water will come out. Remove the filter and clear all lint, coins, or debris. Replace and run a Drain/Spin cycle.
Check the drain hose.

Pull the machine away from the wall and inspect the drain hose. Straighten any kinks. The hose should be inserted no more than 15 cm into the standpipe — inserting it deeper creates a siphon that slows drainage.
Check the standpipe.

Pour a bucket of water into the standpipe. If it drains slowly, the household drain is partially blocked — not a washing machine fault. Contact a plumber.
Press Pause/Cancel to clear the error and restart.

After cleaning the filter, press Pause/Cancel twice to clear the F21 code. Select Drain/Spin and run it to confirm the machine now drains correctly.

When to Call a Professional

If the pump filter is clean and the drain hose is clear but F21 keeps returning, the drain pump is wearing out and draining too slowly — have a technician replace the pump.
