Siemens washing machine E23 error code
E23 means leak detected (aquastop). Water has been detected in the base tray — the AquaStop protection triggered..
Usually fixable at home · Fault type: Electrical/hardware
Safe checks, in order of likelihood
- Unplug. Tip the machine back slightly and check the base tray for water.
- Look for visible leaks from hose connections and the door seal.
- Dry the tray, reconnect and run a short programme watching for leaks.
Call a professional when…
Find and fix the leak first; a repeat with no visible leak needs a professional — the flood switch or a hidden hose leak may be the cause. If the code returns after these checks, book a qualified engineer.
