My dishwasher is leaking soapy water and there is standing water near the propulsion wheel

Question

Accepted Answer

The issue of soapy water leaking from your Roper RUD1000KB3 is generally caused by excessive foam overflowing from the door seal or blocking the drainage system. Here are the essential checks to perform in order.

First, check the type and amount of detergent. Use exclusively an automatic dishwasher detergent: never liquid soap, laundry detergent, or handwashing products. These products create excessive foam that causes leaks. Reduce the amount used — too much detergent, even of the right type, can generate foam that overflows from the door seal during the initial fill (about 9 liters per cycle for this model). If you have recently changed detergent brands and the foam has worsened, try another brand known for producing less foam.

Inspect the door seal. The rubber around the door should not be cracked, sticky, deformed, or misaligned. If the seal is dirty, gently clean it with a damp cloth. Close the door firmly until it clicks to ensure a complete seal — an imperfect closure allows water to leak from the first fill.

Clean the filter and check the drainage. Access the filter screen at the bottom of the interior tub, under the lower rack. Remove accumulated debris (crumbs, grease, food residues) with your fingers or a paper towel. A clogged filter obstructs drainage and causes water levels to rise. Also, check that the drainage hose is not kinked, stuck, or clogged, and clean the backflow prevention device (on the external plumbing) if it exists.

Check the spray arm and the positioning of the lower rack. Standing water near the propulsion wheel (spray arm) may indicate that the lower rack is not properly seated or that an object is obstructing the free rotation of the arm. Ensure that the rack is properly in place with the stops facing the door, and that nothing is hindering the rotation of the spray arm. Also, check that the overflow protection device (front right corner of the tub) moves freely up and down — an object stuck underneath can immobilize it.

If the problem persists after these checks, contact Roper customer service at 1-800-807-6777 (Canada). A defective door seal, a faulty drain pump, or a damaged drainage hose may require professional repair.
