Bosch Dishwasher E24 Error Code: Drainage Checks and Next Steps

Start with the drain route

Bosch’s UK page describes E24 as a failure to drain properly because of a blockage. The Australian manual lists a kinked or blocked waste-water hose, a sealed siphon connection and a loose pump cover among the E24 checks.

Begin by identifying the hose route and drain connection shown in your installation instructions. Look at accessible sections for a bend or compression. A hose hidden behind fitted cabinetry may need an installer or technician to inspect it; pulling the dishwasher out without planning for its connections is not a useful first step.

Check a newly installed drain connection

The connection deserves particular attention if the problem began immediately after installation or plumbing work. The cited manual tells owners to check whether the siphon connection remains sealed.

For installations connected to a garbage disposal, Bosch’s UK support page also calls for checking that the plug has been removed from the dishwasher drain connection. This instruction concerns that specific arrangement. It is not a reason to alter a connection on an installation that has no disposal unit.

Inspect the pump cover using the correct manual

The cover is beneath the filter. Bosch includes a loose cover in its E24 guidance, so establish that it is fitted correctly before assuming the pump has failed.

Where the manual permits owner access, disconnect power and follow its removal sequence. Bosch’s Singapore cleaning page warns about glass fragments in this area and calls for protective gloves. It describes more than one cover fastening; use the procedure that matches your appliance, rather than forcing a clip or copying another model’s diagram.

Refit the cover and filter exactly as instructed. The Australian E24 table specifically calls for locking the cover correctly.

If E24 keeps returning

A recurring message after the accessible checks needs further diagnosis. Bosch advises contacting support or arranging an engineer when the problem persists.

Tell the technician whether the dishwasher drained at all, when E24 appeared and whether the installation or plumbing recently changed. Include what you found at the hose route, connection and cover. These observations help narrow the inspection without treating the display as a diagnosis of a particular replacement part.

E25 has a separate Bosch support description focusing on the drain pump and its cover. Use the complete displayed code to choose the correct reference.
