Miele Dishwasher F24 Error Code: Causes and Fixes

The F24 error on your Miele Dishwasher means there is a problem with the drain pump or drainage system. This code indicates the dishwasher is unable to drain water properly, which prevents the cycle from completing.

What the F24 error means

The F24 error code on Miele dishwashers signals a drainage system failure. When this error appears, the dishwasher has detected that water is not being evacuated properly during the drain cycle. The control board monitors the drain pump operation and water level, and when it senses abnormal conditions—such as the pump running but water remaining in the tub—it triggers the F24 code to prevent water damage and further complications.

Common causes

• Clogged drain pump or impeller blocked by food debris, broken glass, or small objects
• Kinked or blocked drain hose preventing water from flowing out
• Clogged air gap or garbage disposal connection at the sink
• Failed drain pump motor that cannot generate sufficient pressure to evacuate water
• Faulty drain pump relay or wiring connection on the control board
• Blocked drain filter or sump area filled with food particles and debris

How to fix the F24 error

1. Turn off power and remove standing water — Disconnect the dishwasher from power at the circuit breaker. Use towels and a shallow container to remove any standing water from the bottom of the tub. This makes inspection and repair safer and cleaner.
2. Clean the drain filter and sump area — Remove the lower dish rack and locate the cylindrical filter assembly at the bottom of the tub. Twist counterclockwise to remove it, then clean out all food debris, grease buildup, and foreign objects. Inspect the sump area underneath for any blockages and clear them thoroughly.
3. Check the drain pump for blockages — Access the drain pump by removing the kickplate at the bottom front of the dishwasher. You may need to tip the dishwasher slightly or remove the lower spray arm and filter housing. Inspect the pump impeller by rotating it manually—it should spin freely. Remove any debris, bone fragments, or objects jamming the impeller.
4. Inspect the drain hose — Follow the drain hose from the dishwasher to the sink drain or garbage disposal connection. Check for kinks, clogs, or improper installation. The hose should have a high loop or air gap to prevent backflow. Disconnect and flush the hose with water if you suspect a blockage inside.
5. Check the garbage disposal and air gap — If your dishwasher drains into a garbage disposal, ensure the knockout plug was removed during installation. Run the disposal to clear any clogs. If you have an air gap on the sink, remove the cap and clean out any debris that may be blocking the opening.
6. Test the drain pump operation — Restore power and run a drain cycle or short wash cycle. Listen for the drain pump motor—it should hum or run smoothly. If the pump is silent or makes grinding noises, the motor may be burned out and requires replacement. A genuine Miele drain pump costs $150–$250 plus labor.

FAQ

Can I reset my Miele dishwasher to clear the F24 error?
You can try resetting by pressing and holding the Start button for several seconds or turning off power at the circuit breaker for 5 minutes. However, the F24 error will return if the underlying drainage problem is not resolved. A reset only clears the code temporarily.

Is it safe to run my Miele dishwasher with the F24 error?
No, you should not run the dishwasher when the F24 error appears. Continuing to operate with a drainage failure can cause water to overflow, damage electrical components, or flood your kitchen floor. Address the drainage issue before using the dishwasher again.

How much does it cost to fix a Miele dishwasher F24 error?
If the problem is a simple clog in the filter or drain hose, you can fix it yourself at no cost. Professional service calls typically run $100–$200 for diagnosis and cleaning. If the drain pump needs replacement, expect total costs of $250–$450 including parts and labor.
