Bosch Dishwasher E22 Error Code

Filter is blocked. Here is what it means and how to clear it, easiest fix first.

E22
Easy DIY fix

Food debris has built up in the filter at the bottom of the tub, so water can't circulate properly. It often appears when the filter hasn't been cleaned for a while or dishes go in with a lot of food still on them.

Newer US models show E9240 for the same fault. Some European guides list a related E92 code for dirty or clogged filters.

Safety first: unplug the dishwasher (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix Bosch E22

  1. Remove the filter

    Switch off the dishwasher, take out the bottom rack, and twist the filter out of the floor of the tub. Your manual shows the exact steps for your model.

  2. Clean it well

    Rinse the filter under running water and scrub gently with a soft brush and a little mild dish soap to clear trapped grease and debris. Rinse again.

  3. Refit it so it locks

    Put the filter back and turn it until it locks in place. A filter that isn't locked can cause poor cleaning and more errors.

  4. Clean it regularly

    Check and rinse the filter every few weeks, more often if you don't scrape plates first. Run a short cycle to confirm the code has cleared.

When to call a technician

If the filter is clean and locked in but E22 keeps appearing, have a technician check the wash pump and circulation system.

Can I fix Bosch E22 myself?

Usually, yes. Most E22 problems clear with simple checks you can do at home. Start with the first step above: remove the filter.

What if E22 keeps coming back?
