Bosch Dishwasher E23 — Drain Pump Support

What E23 means

Bosch US describes E23 as an issue with the drain pump, with blockage, clogging or a faulty pump listed as possibilities. The code alone does not confirm a relay failure or tell you which part to replace.

What to do next

Contact Bosch support for assistance. That is the action given in the manufacturer’s E23 section. Use the official E23 support page to reach the manufacturer.

This guide does not turn those possible causes into an instruction to remove, test or replace a pump. It provides no electrical testing or dismantling procedure. If support recommends a check, establish that the instructions apply to your exact model before proceeding.

Prepare your model information

Have the full model number and exact displayed code ready. Describe what happened before the error appeared and any observations already available, without dismantling the dishwasher to collect more information. The Bosch owner-manual lookup uses your model number to locate its documentation.

Should I reset or replace something?

The cited E23 section provides no timed reset or pump-replacement procedure. This page therefore does not prescribe a universal reset duration, a filter location, or a replacement part. Follow the manufacturer support route rather than treating a generic checklist as a diagnosis.

Limits of this guide

The scope is Bosch US public E23 support. We have not inspected your appliance or established model-specific repair applicability, cost or duration. For another market or a different code format, consult the appropriate Bosch service and the documentation for your exact model.
