## Direct answer

Bosch Dishwasher E23: a drain-pump fault caused by a blocked, clogged, or faulty pump. This interpretation applies to Bosch dishwasher models covered by the linked official US E23 support article in United States / English.

## Exact scope

- Brand: Bosch
- Appliance: Dishwasher
- Error code or indicator: E23
- Model scope: Bosch dishwasher models covered by the linked official US E23 support article
- Region: United States / English

## What users may observe

- E23 is shown on the Bosch dishwasher display, indicator, or connected app
- The published condition is: a drain-pump fault caused by a blocked, clogged, or faulty pump
- Water or condensate does not leave through the documented drain path as expected while E23 is active
- The important observation is when E23 appears and whether the exact published action changes that condition

## Causes or fault boundaries

- Manufacturer-defined fault area — a drain-pump fault caused by a blocked, clogged, or faulty pump
- E23 does not distinguish an accessible restriction, hose installation, household drain, pump, wiring, or control until the drain path is checked
- Model boundary — apply this interpretation only to Bosch dishwasher models covered by the linked official US E23 support article

## Verified diagnosis

- Photograph the complete E23 display before changing controls or removing power
- Confirm that the full model number is covered by this scope: Bosch dishwasher models covered by the linked official US E23 support article
- Confirm that the observed condition matches the published meaning: a drain-pump fault caused by a blocked, clogged, or faulty pump
- Switch the dishwasher off
- Check only the user-accessible filter for obvious debris
- If the code remains, contact Bosch service because Bosch identifies a blocked, clogged, or faulty drain-pump condition
- Published check — No model-independent drain-pump repair is published for this code
- Published check — Clean only the user-accessible filter, then arrange Bosch service if the code remains
- Stop at the published service boundary after these actions; do not add a restart or test cycle that Bosch does not specify for E23

## Evidence-backed actions

- No model-independent drain-pump repair is published for this code
- Clean only the user-accessible filter, then arrange Bosch service if the code remains
- Give service the E23 photo, full model and serial number, when it appeared, and the result of every published external check

## Safety boundary

Stop the dishwasher and contact Bosch Customer Support. Do not open or test the drain pump or live wiring from the code alone. Stop if there is water, heat, smoke, a burning smell, or unsafe electrical behavior. Do not open fixed panels or test live circuits.
