• Obstructions or internal collapse may contribute to slow or incomplete draining

• Disconnect power and turn off water supply before servicing
• Expect residual water; use towels or a pan when removing the old hose
• Note hose routing and clamp positions; seat fully on each port and secure with appropriate clamps
• Run a quick fill/drain test and check all connections for leaks after installation

Size: 90 inches long. To order hose extension use 12001585. To order siphon break use 76660.

The Tub Cover Gasket is an OEM part for Whirlpool washing machines. This part creates a watertight seal between the tub cover and the tub, preventing water from leaking during the wash cycle.

This small retaining clip secures components in place inside the appliance, helping prevent movement, vibration, and premature wear. Replace a bent, fatigued, or missing clip to restore a solid, factory-tight hold.

• Holds panels, brackets, or tubing securely in their mounts
• Helps maintain alignment to reduce rattles, rubbing, or intermittent issues
• Common signs of failure: missing clip, loose fit, buzzing/vibration, parts that won't stay seated
• Restores proper retention after service, transport, or vibration-related fatigue

• Disconnect power and shut off gas/water before servicing
• Note the original clip's orientation; remove with needle-nose pliers
• Seat the new clip fully—do not over-bend; spring tension provides the hold
