The E24 error on your Siemens Dishwasher means there is a drainage problem preventing water from leaving the appliance properly. This is usually caused by a blockage in the drain system or a faulty drain pump.

|---|---|

What the E24 error means
The E24 error code indicates that your Siemens dishwasher has detected a problem with draining water. The appliance has sensors that monitor the drainage process, and when water fails to drain within the expected time frame, the error is triggered and the cycle stops. This is a protective measure to prevent flooding and potential water damage to your kitchen.
Common causes
- Blocked or kinked drain hose preventing water from flowing out
- Clogged filter or drain pump housing filled with food debris, broken glass, or small objects
- Blocked sink drain or waste pipe that the dishwasher drains into
- Faulty or jammed drain pump unable to expel water
- Blocked air gap or check valve in the drainage system
- Electrical connection problem between the control board and drain pump
How to fix the E24 error
- Check and clean the filter Turn off the dishwasher and open the door. Remove the lower spray arm if necessary, then unscrew or lift out the filter assembly at the bottom of the tub. Rinse it thoroughly under running water to remove food particles, grease, and debris. Check the sump area beneath the filter for any objects like broken glass, bones, or fruit stones that may be blocking the drain.
- Inspect the drain hose Pull the dishwasher out from under the counter and locate the drain hose at the back. Check for kinks, twists, or damage along its length. Disconnect the hose from the sink drain or garbage disposal and check for blockages. Use a long brush or run water through it to clear any obstructions. Ensure the hose is not installed higher than 100cm from the floor.
- Check the sink drain connection Ensure your kitchen sink drain is not blocked, as dishwashers typically drain through the same waste pipe. If you have a garbage disposal, make sure the knockout plug has been removed from the inlet port. Run your sink to verify it drains freely. If water backs up, you may need to clear the sink trap or waste pipe first.
- Test the drain pump With the dishwasher still pulled out and powered off, locate the drain pump at the base of the unit. Remove any covers and check the pump impeller can spin freely by rotating it with your finger. Remove any debris wrapped around the impeller. Reconnect power and start a drain cycle to listen for the pump running. If it makes no sound or hums without pumping, the pump motor may be faulty and needs replacement.
- Reset the dishwasher After clearing any blockages, reset the error code by turning off the dishwasher at the power supply for 5 minutes, then switching it back on. Run a rinse cycle to test whether the drainage system is working correctly. If the E24 error returns immediately, there may be a more serious pump or control board issue requiring professional repair.
FAQ
Can I reset the E24 error without fixing the problem?
You can reset the error by powering off the dishwasher for a few minutes, but the E24 code will return if the underlying drainage problem is not resolved. The dishwasher will not complete cycles properly until the blockage or fault is fixed.
Why does my Siemens dishwasher show E24 even after cleaning the filter?
The filter is just one potential cause of the E24 error. If cleaning it does not resolve the issue, check the drain hose for kinks or blockages, ensure the sink drain is clear, and verify the drain pump is working correctly. The pump itself may be faulty or the drain hose may be improperly installed.
Is it safe to use my dishwasher with an E24 error showing?
No, you should not use the dishwasher when the E24 error is displayed. The error indicates water is not draining properly, which means water will accumulate in the bottom of the tub and cycles will not complete. Continued use could lead to flooding or damage to the appliance components.
