Description

Replacement tube that channels water inside the appliance to restore proper flow and help prevent leaks, pooling, or poor performance when the original is cracked, kinked, or deteriorated for reliable operation. What it does:

• Routes water between internal components to maintain normal circulation.
• Stops properly when replaced if the original is cracked, split, hardened, or leaking.
• Common symptoms indicating replacement: visible leaks, puddling under the appliance, reduced water flow, or inconsistent cycle performance.
• Reinstall with proper clamps and routing to avoid kinks and ensure a watertight connection.

What's included: One tube. Install notes:

• Disconnect power and shut off the water supply before starting any repair.
• Drain remaining water and relieve pressure in lines to minimize spills.
• Remove access panels as needed and note the tube routing/orientation before removing the old part.
• Install the new tube without sharp bends, secure with the correct clamps or fittings, then restore power/water and check thoroughly for leaks.
