Applicability
Regional guidance · Bosch dishwashers covered by the Germany support index · Germany
This scope follows Bosch's Germany dishwasher support index; E23/E6101/E61-01 display families and service guidance can differ by exact model and market.
Reset or retry steps
- The cited E23 entry directs owners to Bosch support and does not give an owner pump-access or reset procedure.
When to call a technician
- Call Bosch support for E23, E6101, or E61-01.
- Call service if the pump area is blocked, damaged, or not safely accessible.
Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
Can I keep using it?
Stop normal use when water is visible or a leak warning is active. Stay clear if water could reach wiring or controls.
- Safe next step
- Follow the code-specific shutdown or protective-drain instructions, turn off water when appropriate, and avoid repeated resets. Do not interrupt a documented protective-drain sequence just to clear the display.
- Stop when
- Water is near wiring, cabinetry is getting wet, the leak returns, or the source is not safely visible.
Do not keep using the appliance if the code points to voltage, wiring, control power, burning smell, smoke, or a possible miswired supply.
- Safe next step
- Use only safe owner-level power checks, then involve a qualified technician or electrician when the source points to wiring or supply voltage.
- Stop when
- Breakers trip, lights dim, the appliance smells hot, wiring may be miswired, or the warning returns after a safe reset.
Safety boundaries
Safe first
- Match the exact brand, appliance type, and displayed code first.
- Use the model manual as the final authority for access steps.
- Disconnect power before any service-access step.
Do not do this
- Do not continue normal cycles while this code is active; any protective-drain sequence must follow the exact model instructions.
- Do not open drain or pump areas while the appliance is powered.
- Do not bypass locks, float switches, leak sensors, or other safety systems.
Common causes include
- Drain pump blocked or clogged by debris
- Drain pump fault
FAQ
What does Bosch Dishwasher code E23 usually mean?
This code commonly points to an issue with the drain pump, such as a blocked, clogged, or faulty pump. Model context matters: Bosch's U.S. error-code guide describes E23 as a drain-pump issue that may be blocked, clogged, or faulty, but the display does not identify which condition applies.
Can I keep using the dishwasher with code E23?
Stop normal operation until the issue and safety warnings have been addressed. Follow only the documented safe checks or protective-drain instructions for your model. Disconnect power before drain-pump access.
When should I call a technician for Bosch E23?
Call Bosch support for E23, E6101, or E61-01. A qualified technician may check Drain pump against the model's service information before treating any part as failed.
