Summary

Siemens SN65M037EU/B3 error code e22 points to a blocked dishwasher filter or restricted water flow through the filter area. This guide shows the safest cleaning steps and what to check next if the fault returns.

Fix it fast

  1. Switch the dishwasher off and open the bottom filter area.
  2. Remove the filter assembly and rinse it under running water.
  3. Clear any food debris, labels, or glass fragments from the sump and filter housing.
  4. Reinstall the filter correctly and rerun a short cycle.

What e22 means

e22 usually means the dishwasher has detected restricted flow caused by a blocked filter area. Until the blockage is cleared, wash and drain performance can both suffer.

Common mistakes

  • Cleaning only the visible mesh and not the full filter assembly.
  • Reinstalling the filter loosely so water can still circulate incorrectly.
  • Ignoring labels, seeds, or glass fragments trapped below the filter.

When to contact support

Book service if e22 comes back immediately after a thorough filter clean, because a deeper blockage or pump issue may still be present.
