Dishwasher E24 Error: How to Fix the Drainage Problem
2026-10-31
What Is the Dishwasher E24 Error?
If your dishwasher suddenly stops during operation and the E24 code flashes on the screen, this generally indicates that the machine cannot drain water or is experiencing a drainage problem. Modern dishwashers can lock themselves via sensors as a safety measure in situations where water cannot be expelled. The E24 error is a type of malfunction that users can often address with simple methods at home, though it may sometimes require technical service.
Causes and Checkpoints for the E24 Error Code
Before panicking when you encounter this error code, you should perform the following checks to identify the source of the problem:
- Clogged Drain Hose: The most common cause is a kinked or clogged drain hose under the sink.
- Drain Pump Obstructions: Broken glass, coins, or food residue that has entered the drain pump impeller may be preventing the pump from rotating.
- Filter Cleaning: Grease and debris accumulated in the filter at the bottom of the machine can restrict water flow and slow down the drainage system.
- Waste Water Drain Connection: If your machine was recently installed, the plastic plug at the mouth of the hose connected to the drain not being removed can cause this problem.
Step-by-Step E24 Troubleshooting Guide
You can follow these methods to resolve the E24 error:
1. Clean the Filters: Remove the strainer and filters at the bottom of the machine. Clean all residue with warm soapy water and a soft brush. Make sure the filter pores are open.
2. Access the Pump: In many models, there is a white or transparent cover directly below the filter housing. Carefully open this cover to check the drain pump impeller. Use your finger or a pair of tweezers to remove foreign objects wrapped around the impeller. Check whether the impeller rotates freely.
3. Check the Drain Hose: Follow the gray drain hose at the back of the machine. Check the hose for any kinks or compression. If possible, remove the hose and run water through it to test for blockages.
4. Inspect the Siphon Connection: Check the sink siphon that the dishwasher is connected to. If the siphon is clogged, the machine cannot drain water. Test whether the sink is draining properly.
Final Checks Before Calling Service
If the E24 error persists despite performing all physical cleaning steps, the problem may be with the electronic board or the drain pump motor. Electronic board failures are too complex to repair in a home environment. In such cases, the healthiest course of action is to cut the machine's power connection and seek support from a professional technical service.
Important Warning: Make sure to disconnect the machine's power connection and close the water inlet valve before performing any cleaning or inspection. Dishwasher parts can be sharp; wearing protective gloves during cleaning is recommended.
