KitchenAid Dishwasher - Drain Issues
Model: KDTM604KBS1
Location: Estero, FL 33928
Repair Summary
Checked dishwasher for drain issues. Upon arrival, found an F9E1 error code indicating a drain problem. Tested the dishwasher and verified it filled and began the wash cycle properly. Canceled the cycle and found that the dishwasher did drain, but the water flow was very slow with limited pressure. Determined the drain pump may be getting weak and ordered a replacement.
Returned and installed the new drain pump. During further inspection, found the dishwasher drain hose has been extended with a second hose, making the overall drain hose approximately twice the proper length. This is an installation issue and is restricting the drain flow, likely because the original hose did not reach the sink drain connection. Tested the drain at the junction of the two hoses and verified good water flow and pressure. However, when connected to the sink drain, the flow remained very slow. The drain pump was replaced due to its weakening performance, but the extended drain hose is still causing a significant restriction. Attempted to contact the owner but received no answer. Advised that the drain hose installation needs to be corrected, as the dishwasher may continue experiencing drain issues until the restriction is resolved. Dishwasher is operating properly at this time aside from the slow drain flow to the sink.
