GE Dishwasher Drain Hose Replacement — What This Part Does
The drain hose is a flexible corrugated tube that carries wastewater from the dishwasher pump to your sink drain or garbage disposer. It must have a high loop or air gap to prevent dirty water from siphoning back into the tub. Over time the hose can kink, split, or clog with food debris and grease, blocking the flow and leaving water in the bottom of the tub.
Common failure points are tight bends where the hose exits the cabinet, loose or corroded clamps at the pump or disposer connection, and internal buildup that narrows the passage. A cracked hose will drip or spray water onto the floor during the drain cycle. If the hose is routed too low or lacks a proper loop, backflow from the sink can flood the dishwasher even when it is off.
Signs It Needs Replacing
- Standing water in the tub after a cycle Water remains in the bottom of the dishwasher because the drain hose is kinked, clogged, or disconnected.
- Slow draining or gurgling noises The dishwasher takes a long time to empty or makes bubbling sounds as air struggles through a partial blockage in the hose.
- Water pooling under the dishwasher A cracked, split, or loose hose connection sprays or drips water onto the floor during the drain cycle.
- Backflow or dirty water returning to the tub Sink water or disposal waste flows back into the dishwasher because the hose lacks a high loop or air gap.
- Visible kinks or crushed sections of hose The hose is pinched by the cabinet, bent too sharply, or compressed where it passes through the wall or floor.
- Foul odor from the dishwasher interior Food debris and grease trapped inside the drain hose decompose and produce a sewer smell even after cleaning the filter.
How to Replace It
- Unplug the dishwasher from the wall outlet or turn off the circuit breaker at the panel, then shut off the water supply valve under the sink.
- Place towels on the floor and remove the lower front access panel by unscrewing the retaining screws along the bottom edge.
- Locate the drain hose where it exits the dishwasher pump or collection chamber and trace it to the sink or garbage disposer connection under the cabinet.
- Loosen the hose clamp at the dishwasher end with pliers or a screwdriver, then pull the hose off the pump outlet and let any trapped water drain into a shallow pan.
- Disconnect the other end of the hose from the sink drain or disposer by loosening the clamp or removing the retaining bracket, then pull the hose free.
- Inspect the old hose for cracks, splits, kinks, or internal blockage, and compare its diameter and length to the new replacement hose.
- Route the new hose from the dishwasher pump to the sink connection, forming a high loop that rises as close to the underside of the countertop as possible to prevent backflow.
- Slide new hose clamps onto each end, push the hose firmly onto the pump outlet and the sink drain or disposer nipple, then tighten the clamps securely.
- Replace the lower access panel, restore power and water, then run a short rinse cycle and check both hose connections and the floor for any leaks.

When to Call a Pro
If you find no damage or blockage in the drain hose but water still will not leave the tub, the drain pump or check valve may be faulty and require electrical diagnosis. If your dishwasher is built in and you cannot safely pull it forward to access the hose routing, or if the drain connection is hard-plumbed into a wall drain line instead of flexible tubing, call a technician to avoid damaging cabinetry or plumbing. Any time you see water leaking from inside the door or around the tub gasket rather than from the hose area, the problem is upstream and needs professional inspection.
