F21Warning
Maytag Dishwasher F21 Error Code
The dishwasher is taking too long to drain water. Usually indicates a clog or pump issue.
Common causes

- Blocked garbage disposal
- Faulty drain pump
- Loose or blocked check valve
How to fix it
- Clean the drain hose and air gap of debris.
- Check and clear the garbage disposal knockout plug if new install.
- Inspect drain pump for obstructions like broken glass or food.
- Run a rinse cycle to see if code clears.
⚠ When to call a pro: If the drain hose is clear but code persists, the drain pump likely needs replacement.
