Bosch Dishwasher Error Code E22: Filter Blocked

Clear meaning, realistic next steps, and safe guidance without turning the page into a long repair manual.

What it means

Bosch dishwasher error E22 usually means the filter is blocked badly enough to slow water movement through the machine.

Severity

Low - usually safe to check with basic user-accessible cleaning or inspection on the Bosch dishwasher.

Can you fix it yourself?

Yes — DIY-safe

Most likely cause

Food particles clogging the mesh filter at the bottom of the tub

Estimated time for safe first checks: 5–15 min.

Step-by-Step DIY Fix Guide

  1. SAFETY: Turn the dishwasher off before removing the filter assembly.
  2. Remove the lower rack, unlock the cylindrical filter, and take out both the main filter and the flat filter beneath it.
  3. Rinse both filter pieces thoroughly under warm water and scrub away greasy residue with a soft brush.
  4. Inspect the sump opening for labels, seeds, glass, or other debris before reinstalling the filter.
  5. Lock the filter back into place securely and run a short cycle to see whether E22 clears.

If E22 comes back after a full filter clean

  • If the filter was only lightly dirty, look more closely for residue or scale packed into the mesh or trapped below the filter.
  • If standing water is also left in the tub, compare E24 or E25 because the issue may already have moved into the drain path.
  • If the filter does not lock firmly, the assembly itself may be damaged and no longer guiding flow correctly.

What This Error Means

Bosch dishwasher error E22 means the filter area at the base of the tub needs attention. In most kitchens this is still one of the most user-fixable Bosch dishwasher faults on the site.

The good news is that E22 usually points to the visible filter assembly rather than an internal electrical fault. A proper clean is often enough to clear the warning.

If the filter is cleaned thoroughly and the code still comes back, the next likely issue is a deeper drain-path restriction or a related drain fault such as E24 or E25.

Most Likely Cause by Symptom

The dishwasher stops and the filter area looks dirty or greasy.

Likely cause: The filter mesh is restricting water flow.

Check first: Remove and scrub the full filter assembly rather than only rinsing the top surface.

The code keeps returning even after a quick clean.

Likely cause: Debris is still trapped below the filter or the filter was reinstalled loosely.

Check first: Check the sump opening and confirm the filter locks fully back into place.

Common Causes

  • The cylindrical or flat filter is clogged with food debris.
  • Grease or residue has coated the filter mesh and restricted flow.
  • The filter was not seated correctly after a previous clean.
  • The sump area beneath the filter contains debris that is keeping flow restricted.

What Not to Do

  • Do not keep running full cycles with a visibly dirty or loose filter.
  • Do not scrub the filter with tools that can tear the mesh.
  • Do not assume the control board is at fault before the filter and sump are cleaned properly.

Model and Display Variation Notes

Model-family notes

  • Bosch dishwasher filter shapes vary by series, but E22 still points first to the tub-base filter assembly.
  • If E22 appears together with poor draining, the fault may overlap with E24 or E25 rather than being a filter-only issue.

Display and panel differences

  • Panel wording can vary by series, so confirm the exact code pattern before buying parts.

Parts, Tools and Service Options

When Not to Keep Troubleshooting

  • The filter assembly is damaged or will not lock properly.
  • The dishwasher still shows drain symptoms even with a clean filter.

How to Prevent It Recurring

  • Clean the filter every 4 weeks
  • Scrape plates before loading — the filter is not a garbage disposal
