The dishwasher displays E22, with standing water and dirty filters remaining after a cycle.

Safety first: Turn off the power before reaching into the sump; broken glass may be present.

• 1. Remove and clean filters: Take out the coarse and fine filters. Wash them thoroughly under hot running water with a brush to remove grease and debris.
• 2. Inspect sump area: Shine a light into the sump. Remove any visible debris, labels, or foreign objects.
• 3. Check sump cover and seals: Ensure the filter assembly and sump cover are correctly seated and not warped. Misalignment can restrict water flow.
• 4. Run a rinse cycle: After cleaning, run a short rinse program to confirm proper drainage.

When to call a technician: If E22 persists despite a clean sump and filters, there may be a deeper blockage or pump issue requiring professional service.
