Bosch Dishwasher E22 Error Code

Meaning: The fine mesh filter at the bottom of the dishwasher is blocked or clogged, preventing proper water drainage and circulation.

Risk: Low. No safety hazard. This is a routine maintenance issue. Cleaning the filter usually resolves E22 immediately.

First safe checks:

Open the dishwasher and remove the bottom rack.
Locate the filter assembly at the bottom of the tub — it typically twists and lifts out.
Separate the fine mesh filter from the coarse filter.

Call a technician if:

The filter is clean but E22 persists.
Water does not drain even with the filter removed (points to pump or drain issue, not filter).
The filter housing is cracked or damaged.

Common causes
