Frequently Asked Questions

What does Siemens Error F23 mean?

F23 is triggered by the anti-flooding sensor in the base of the machine. It activates when water accumulates in the machine base due to an overflow or internal leak.

Can too much detergent cause Siemens F23?

Yes — excess detergent creates heavy sudsing. If foam rises above the drum and spills into the base, the anti-flood sensor triggers F23. Use the correct amount of HE (low-suds) detergent.

How do I reset Siemens Error F23?

Once you have identified and fixed the cause, tilt the machine to drain any water from the base. Allow the base to dry completely, then perform a power reset before restarting.
