What it means

This code appears on Bosch dishwashers when the filter set in the bottom of the tub is blocked with food debris, reducing water flow to the circulation pump, and the program may stop. It is usually fixed by cleaning the filters, and is sometimes linked to a drain blockage or a weak circulation pump. The meaning should be confirmed for your model, and the same number can mean something else on other brands.

Models covered: Bosch dishwashers; the code shows on the display or at the end of a program.

Symptoms4

E22 shows and the program stops or ends with poor results.
Food residue on dishes and grit on glasses.
Uneven pumping sound or a sucking noise from the bottom.
A bad smell from the bottom of the tub.

Possible causes5

Filters blocked with food and grease because they are not cleaned regularly.
Loading dishes with a lot of leftover food without scraping.
Filters not fitted or not locked properly.
A blockage in the drain path causing debris to build up.
A weak circulation pump that the unit reads as low water flow (less common).

How to diagnose5

Unplug the unit and take out the lower basket.
Remove the filter set (cylinder and flat filter) and clean it with warm water and a soft brush.
Clean the filter housing in the bottom and make sure it is free of debris.
Refit and lock the filters by the manual markings, then run a short program.
If the code returns with clean filters, a technician unplugs the unit before taking it apart and checks the circulation and drain pumps.

How to fix5

Clean the filters and refit them firmly.
Scrape off large food debris before loading.
Make filter cleaning a regular habit as the user manual advises.
Have the technician clear a drain blockage or replace the drain pump if needed.
Run a full program and confirm clean dishes and no returning code.

Frequently asked questions

How often should I clean the dishwasher filters?

It depends on use and debris, and user manuals advise checking and cleaning them regularly, more often when washing heavily soiled dishes.

Why do you say the meaning should be confirmed?

The meaning of E22 can differ slightly between Bosch dishwasher series, so check it against your manual, although cleaning the filters is a safe step either way.

Should I fully rinse dishes before loading?

There is no need; scraping off large debris is enough, but leaving big pieces of food blocks the filters quickly.
