Frequently asked questions

What does E26 mean on a Bosch dishwasher?

On many model families, E26 indicates that the water switch or flow control is abnormal. Confirm the exact model and region because the same display can be used differently.

Can I clear E26 by unplugging the dishwasher?

A short power reset may clear a temporary state, but it will not fix a blocked hose, leak, failed sensor, motor, heater, or wiring fault. Stop if the code returns.

Should I replace a part based only on the code?

No. A code identifies a system or condition, not always the failed component. Complete safe external checks and use the model-specific manual or qualified service.
