Bosch washing machine showing E23 after water on float switch area

The problem

A Bosch washing machine displayed error code 23. The owner reported water on the float and rubbish behind the blue disc, which had been cleaned/fixed, but the display still showed the fault and they wanted a reset combination.

Likely cause

The discussion supports an anti-flood/float switch fault still being detected. The accepted advice was that Bosch error codes normally clear automatically once the underlying fault is properly rectified, so a remaining indication suggests the float switch may still be activated or the fault condition has not fully cleared.

What fixed it

No reset code or button combination was confirmed. Recommended action was to recheck that the float switch is no longer stuck on and that the water/rubbish issue has been fully cleared. If the fault remains after that, further diagnosis should be carried out by a suitably qualified appliance engineer.

Checks to try

• Checked for water on the float
• Found rubbish behind the blue disc
• Advised to check whether the float switch was still stuck on
