Dirty water tank sensor light stays on, but there is no electronic error code and unit still runs intermittently

Safety: Unplug the unit and remove the dirty water tank.

• Clean float: Open the tank and locate the float. Rinse with warm water and mild detergent to remove residue.
• Check movement: Move the float up and down to ensure it travels freely. If it catches, inspect for burrs or warping.
• Replace float assembly: If the float or guide is deformed, replace the float assembly or tank.
