Bosch E24 Drainage Fault Solved on a Bosch dishwasher usually traces to a blocked drain pump, clogged filter, or kinked drain hose. This guide covers how the fault presents, the parts we test first, and how we confirm the cause before any part goes in.

A Drain That Cannot Clear
A Bosch E24 means the dishwasher cannot drain within its expected time. The classic culprits are a clogged filter, a drain hose with a collapsed high loop, a blocked sink air gap, or debris caught in the drain pump impeller. You usually see it as standing water in the tub after the cycle ends, sometimes with a faint smell from water that has sat.
The Order We Work
We pull and clean the filter and sump, check the hose routing and the air gap, and confirm the drain pump spins freely and pumps to spec. On many E24 calls the fix is a thorough cleaning and a corrected hose rather than a part. Where the pump has failed we fit a model-specific Bosch pump and verify a clean drain across a full cycle before we finish.
