Bosch Dishwasher E23: Drain-Pump Fault and Service Guidance
THE SHORT ANSWER
A drain-pump problem, such as blockage or a faulty pump.
E23 is Bosch’s drain-pump problem entry. A blockage or a faulty pump may be involved, but the display alone does not distinguish them. Bosch directs owners to customer support.
Record E23 and the complete model number for the service request.
Do not perform powered pump tests or reach into inaccessible parts.
WHAT YOU MAY NOTICE
Symptoms to record
- E23 is shown on the dishwasher display.
UNDERSTAND THE POSSIBILITIES
Causes & useful observations
A code identifies a condition. It does not, by itself, confirm which part needs repair.
| Possible cause | What to look for | Safe check / next step |
|---|---|---|
| Blocked or faulty drain pumpService may be needed | E23 reports a pump concern without identifying the cause. | Record visible standing water, if any, without opening service panels. |
WORK THROUGH THE BASICS
Safe troubleshooting checks
Use the checkboxes to keep track as you read. Stop at any warning or step that does not match your appliance.
Take a clear display photo so E23 is not confused with E22, E24, or E25.
What to noteThe code is accurately recorded.
Note when the cycle stopped and any water visible inside the tub.
What to noteService receives the actual symptoms rather than an assumed diagnosis.
Use Bosch’s official support resource and supply the model identifier.
What to noteA qualified assessment can distinguish an obstruction from a pump fault.
