Dishwasher E24 Error: How to Solve Drainage Problems?

2026-10-31

What is the Dishwasher E24 Error?

If your dishwasher suddenly stops working and displays a blinking E24 code on the screen, it usually indicates that the machine is unable to drain water or is facing a drainage issue. Modern dishwashers may lock themselves via sensors as a safety measure when water cannot be expelled. The E24 error is a type of malfunction that users can often address with simple home remedies, though it may sometimes require technical service.

Causes and Checkpoints for E24 Error Code

Before panicking when you encounter this error code, you should perform the following checks to identify the source of the problem:

• Drain Hose Blockage: The most common cause is the kinking or clogging of the drain hose under the sink.
• Drain Pump Obstructions: Broken glass, toothpicks, or food particles that get into the drain pump impeller may prevent the pump from rotating.
• Filter Cleaning: Accumulated grease and waste 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 newly installed, the plastic plug in the mouth of the hose connected to the drain may not have been removed, leading to this issue.

Step-by-Step E24 Malfunction Troubleshooting Guide

You can follow these methods to resolve the E24 error:

1. Clean the Filters: Remove the strainer and filters from the bottom part of the machine. Use warm soapy water and a soft brush to clean all residues. Ensure that the filter pores are clear.

2. Access the Pump: In many models, there is a white or transparent cap just below the filter slot. Carefully open this cap to inspect the drain pump impeller. Use your finger or tweezers to clean any foreign objects tangled around the impeller. Check if the impeller spins freely.

3. Check the Drain Hose: Trace the grey drain hose at the back of the machine. Check for any kinks or compression in the hose. If possible, remove the hose and run water through it to test for blockages.

4. Inspect the Siphon Connection: Check the sink siphon to which the dishwasher is connected. If the siphon is clogged, the machine cannot empty the water. Test if the sink drains properly.

Final Checks Before Calling Service

If the E24 error persists despite performing all physical cleaning procedures, the problem may lie in the electronic board or the drain pump motor. Electronic board malfunctions are too complex to be repaired in a home environment. In such cases, the healthiest path is to cut the machine's power connection and seek support from a professional technical service.

Important Warning: Before performing any cleaning or inspection, ensure that you have cut the machine's electrical connection and closed the water inlet valve. Dishwasher parts can be sharp; it is recommended to use protective gloves during cleaning.
