✅ Cross Reference Information

Common Symptoms

• Water appearing under or near the dishwasher during the drain portion of a cycle.
• Visible cracking, splitting, soft spots, or leakage at the hose or its connections.
• Slow or incomplete draining when the hose is kinked, crushed, obstructed, or incorrectly routed.
• Wastewater flowing back into the dishwasher when the drain hose lacks the required high loop or air gap.

Check Before Replacing

• Disconnect electrical power to the dishwasher and shut off its water supply before inspecting the hose.
• Visually inspect the entire hose route for kinks, crushing, sagging, cracks, splits, or wet areas.
• Check both hose connections for looseness or visible leakage without forcing or over-tightening the connection.
• Verify that the hose is routed according to the dishwasher installation instructions, including the required high loop or air-gap arrangement.
• After inspection or installation, run a short drain cycle while observing the hose and connections for leakage; stop the appliance if water leaks.
