Common Symptoms
- Water remains in the dishwasher tub after a cycle
- Water leakage beneath or around the dishwasher
- Slow draining from a restricted or kinked hose
- Drainage problems after the hose has been damaged or improperly routed
Check Before Replacing
- Disconnect electrical power and shut off the dishwasher water supply before inspecting the hose.
- Visually inspect the accessible hose for kinks, crushed sections, cracks, pinholes, abrasions, or loose connections.
- Check that the hose is firmly attached at the dishwasher drain port and household drain connection, with the clamp properly positioned.
- Inspect the accessible drain path for an obvious obstruction; do not force tools through the hose or disassemble sealed components.
- After any correction, run a short rinse or drain operation and observe the connections for leakage.
Pro Tip
Route the hose with a smooth high loop and avoid sharp bends; a kink or improperly routed hose can restrict drainage and leave water in the tub.
