Unit overfills with water, reservoir or bin floods

Safety: Turn off power and water immediately to stop flooding.

• Check inlet valve: With power off, if water continues to flow, the valve is mechanically stuck open and must be replaced.
• Clean level sensor: Remove scale from the water level probe or float so it can accurately detect water level.
• Inspect drain: Ensure the drain is not blocked, which can make normal water levels appear as overfill.
• Control board: If the valve only overfills when energized and the sensor is clean, the control board may be keeping the valve on too long and require replacement.
