Tools & Materials

Step-by-Step

3. Inspect and clean the filters; remove any debris that might obstruct draining.

4. Check the drain hose for blockages, kinks, or damage and clear or replace as necessary.

5. Examine the drain pump for signs of wear or malfunction; test for continuity with a multimeter.

6. Replace faulty parts as required and reassemble the dishwasher.

Completion Checks

When to Call a Pro Instead

If the leak and drainage issue persists despite basic repairs, or if you encounter complex electrical or water ingress problems, consult a professional appliance repair technician to ensure safety and warranty compliance.
