Washer-dryer combo shows E9 and stops; water is found in the base tray or under the machine

Safety first: Unplug the appliance and close the water supply taps immediately to prevent further leakage.

• Inspect around the unit: Look for visible water at the front, sides, and rear. Dry up any standing water.
• Tilt and drain base: Carefully tilt the Roborock combo slightly backward (with assistance) to allow water in the base tray to drain out onto towels. This may temporarily clear E9.
• Check hoses and gasket: Inspect inlet hoses, drain hose, and the door gasket for drips or cracks while running a short fill cycle (with panels removed and extreme caution).
• Examine internal hoses: Remove the front lower panel and check the tub-to-pump hose, sump hose, and clamps for leaks.
• Repair source of leak: Replace any damaged Roborock hoses, clamps, or door gasket. If the outer tub is cracked, professional replacement is recommended.
