Ice maker overfills with water, water spilling into bin or freezing into a solid block

Safety: Disconnect power and close the water supply valve immediately to stop flooding.

Steps to control overfilling:

• Shut off water: Turn the supply valve fully clockwise to stop water flow. Mop up any standing water to prevent damage.
• Inspect ice tray and fill tube: Remove the ice bin and inspect the fill area. If the fill tube is frozen or misaligned, water may spray incorrectly. Thaw any ice with warm (not boiling) water and reposition the tube.
• Check water pressure: Excessive pressure can cause overfill. If a pressure reducer is installed on the Siemens unit, verify it is functioning. Household pressure should typically be 2–8 bar.
• Test inlet valve: With water supply on and power off, observe if water continues to drip into the ice tray. Any flow with the valve de-energized indicates a mechanically stuck valve; replace the water inlet valve.
• Level sensor / float: Some Siemens ice makers use an electronic level sensor or mechanical float. Inspect for mineral buildup or obstruction. Clean gently and ensure free movement. If the sensor is cracked or corroded, replace it.

If E05 persists: The main control PCB may be mis-timing the fill cycle and should be evaluated by a Siemens technician.
