Risk level

Low

Usually safe to check without specialist tools.

Urgency

Medium

Quick answer

E22 means the dishwasher filter is blocked or not passing water normally. Let the water cool, isolate power and clean only the filter area described in the exact manual.

Safety first

Stop and check this first

  • Do not reach into standing water or an unseen pump cavity. Stop for leaks, hot water, glass, repeated humming or electrical odour.

Safe checks you can perform

  • Stop, cool and isolate the dishwasher
  • Clean only the documented accessible filter
  • Inspect the external drain route

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Trace the complete drain system

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Trace the complete drain system

    What they doService should inspect the sump, pump cover, impeller housing, check valve, hose, sink connection, pump and control.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Stop, cool and isolate the dishwasher

    No special tools

    Cancel the programme, wait for residual water to cool and disconnect the dry electrical supply before opening the door.

    Do not reach into standing water or an unseen pump cavity. Stop for leaks, hot water, glass, repeated humming or electrical odour.

  2. Clean only the documented accessible filter

    No special tools

    Remove and rinse the filter as the model manual shows, reseat it correctly and do not reach into the pump or handle unseen debris.

    Do not reach into standing water or an unseen pump cavity. Stop for leaks, hot water, glass, repeated humming or electrical odour.

  3. Inspect the external drain route

    No special tools

    Look for a crushed hose or blocked sink connection without detaching plumbing, then stop if water remains or the code returns.

    Do not reach into standing water or an unseen pump cavity. Stop for leaks, hot water, glass, repeated humming or electrical odour.

What it means

Bosch's official United States dishwasher table associates E22 with a blocked dishwasher filter. This page is restricted to Bosch dishwashers: the same code on a washer, dryer or another appliance can mean something else, and the exact E-number and manual decide compatibility.
