E09 error, water continuously flows into the ice maker or overflows the sump

Safety first: Turn off the water supply and unplug the unit immediately to prevent flooding.

• Shut off water: Close the supply valve feeding the Teka ice maker to stop the flow.
• Inspect water level control: Access the internal reservoir or sump. Locate the float switch or electronic water level sensor. Check for obstructions, scale, or debris preventing proper movement. Clean with warm water and a soft brush.
• Test float switch: For mechanical floats, use a multimeter to check continuity while moving the float up and down. Replace the switch if it does not change state.
• Check inlet valve: Disconnect the water inlet valve outlet hose and inspect for continuous dripping even when the unit is off. If the valve leaks when de-energized, replace the valve assembly.
• Control board check: If the valve only overfills when powered, verify that the control board is not constantly energizing the valve due to a shorted triac or relay. This typically requires board replacement.
• Restore and test: After replacing faulty parts, reconnect hoses, open the water supply, and run a test cycle to confirm proper fill and shutoff.
