Bosch Dishwasher E24 Error Code: Fix Guide

The Bosch Dishwasher code E24 means: Drain error — the most common Bosch dishwasher code. Water is not draining properly.

Difficulty: Moderate — DIY-able with basic tools

What to do, step by step

1. Check the drain hose at the sink connection — food debris clogs it there most often.
2. Remove and clean the filter at the tub bottom plus the small mesh under it.
3. Check the non-return valve (small flap in the sump) for debris.
4. If clean: test the drain pump — Bosch pumps often fail with worn impellers.
