The pump-to-sump hose is a common source of water leaks under the dishwasher. A cracked, deteriorated, or clamp-loosened hose allows pressurized wash water to escape onto the floor during cycle operation.
A collapsed or kinked hose restricts water flow from the sump back through the circulation circuit, resulting in standing water left in the tub at the end of a wash or drain cycle.
A hole or split in the hose allows wash water to bypass the spray arms. Dishes come out dirty or still greasy because insufficient water pressure reaches the upper and lower wash arms.
Over time — or due to pest damage — the rubber hose becomes hard, brittle, or physically perforated. Any visible deterioration of the hose body or end fittings warrants immediate replacement to prevent flooding.




💡 Pro Tip: Is Your Pump-to-Sump Hose the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Water pooling on the kitchen floor under or in front of the dishwasher after a cycle
⚠️ Dishwasher not draining completely — standing water left in the tub bottom
⚠️ Visible cracks, holes, or chew damage on the black rubber hose connecting the pump to the sump
⚠️ Reduced wash pressure or poor cleaning performance due to water bypassing the circulation circuit
🔍 Diagnosis Tip: Pull the dishwasher forward and inspect the rubber hose running from the circulation pump to the sump housing. Squeeze it gently — brittle, collapsed, or cracked rubber confirms replacement is needed. Also check both clamp ends for corrosion-loosened seals before condemning the pump itself.
