Carpet cleaner shows E9 and will not allow spray or brush functions, often after a spill or tip-over

Safety first: Unplug the unit, especially if it has recently tipped and spilled water.

• Dry the unit: If the cleaner tipped and leaked, wipe all visible moisture. Leave the unit in an upright position in a warm, dry area for 24 hours to allow internal sensors to dry.
• Reset position: Place the cleaner on a flat, level floor. Some models require being upright for several seconds to reset the tilt sensor.
• Power cycle: After drying, plug in and turn the unit off and on to clear the error.
• Internal sensor check (advanced): If E9 persists, open the housing and locate the tilt or spill sensor (often a small switch or mercury-free tilt device). Ensure it is firmly mounted and its wiring is intact.

If the tilt sensor is physically damaged or corroded, it should be replaced to restore safe operation.
