What E23 means
Bosch describes E23 as an issue with the drain pump, which may be blocked, clogged or faulty. The code alone cannot tell you whether the pump, cover, hose or control circuit is responsible.
Primary reference: Bosch US dishwasher error-code index.
Safe checks
- Switch off the dishwasher and note E23 and the E-Nr.
- Follow the exact manual to remove and clean the accessible filter. Do not reach into a pump opening or pry covers with the appliance connected.
- Check the visible drain hose for a sharp kink without disconnecting it.
- If E23 returns, stop and contact Bosch or qualified service. Do not assume the pump is the only failed part.
When to stop
Standing water, sharp debris, a leaking connection or a pump that only hums requires extra care. Isolate power and use service support for any internal pump work.
