What does the Neff E22 error code mean?
E22 on a Neff dishwasher indicates a blocked filter. Shared with Bosch and Siemens, this is the most common dishwasher fault and is always the first thing to check. A clean filter takes less than 5 minutes and resolves the vast majority of E22 cases.
🔍 Symptoms
- Food residue on dishes after washing
- Standing water after a cycle
- Grinding noise during wash
- Spray arms not performing correctly
- Longer cycle times than usual

Frequently Asked Questions (FAQ)
Q: Can I run my Neff dishwasher without the filter?
A: No. The filter protects the wash pump from debris. Running without it will allow food particles and foreign objects to damage the pump impeller, potentially leading to a much more expensive repair.
Q: My Neff dishwasher filter is cracked — does it need replacing?
A: Yes. A cracked filter will allow debris to bypass it and enter the pump. Replacement filters are inexpensive and easy to fit.
Q: Will cleaning the filter improve my Neff dishwasher’s cleaning performance even without E22 showing?
A: Absolutely. A partially blocked filter reduces wash performance gradually before eventually triggering E22. Regular cleaning is one of the most effective maintenance steps for any dishwasher.
