Bosch Washer - E00 / -23 Error Code

Water has collected in the base pan, triggering the leak sensor.

Meaning

Water has collected in the base pan, triggering the leak sensor.

The Bosch E00 / -23 error code indicates that the washer’s leak protection system has detected water in the base pan. Bosch washers use a float switch or moisture sensor to monitor the lower chassis area. When water accumulates—typically from a loose hose, pump leak, or over‑sudsing overflow—the machine stops operation and displays E00 / -23 to prevent electrical damage and flooding. This safety system is part of Bosch’s AquaStop leak protection technology.
