JennAir dishwashers in Los Angeles
JennAir dishwashers in Los Angeles tend to sit behind custom panels in kitchens that were designed as a single piece, from the walnut fronts of a Manhattan Beach remodel to the ocean view estates of Palos Verdes and the newer builds above the Esplanade in Redondo Beach. After 24 years working on these machines, two patterns dominate our call log. The diverter motor that routes water between the racks fails and one level stops washing. And the OWI sensor misreads the load, ending the cycle early and leaving dishes wet no matter which options you press.
Guessing is expensive on this machine because a wet top rack has three unrelated causes and only one of them is the part most shops replace first. We diagnose before we quote, testing the diverter, the sensor circuit, and the heat loop, then price the actual fault. You expect the number to change once the panel comes off. It does not. The visit starts with a $95 diagnostic, waived with your repair, we install genuine OEM parts, most appointments run same or next day, and every repair carries the 3 Year Onyx Warranty.
What actually fails
The failures that put JennAir dishwashers on our schedule.
Diverter motor and wash zone routing
The diverter under the sump aims water at one spray level at a time. When its motor fails or the position feedback drifts, the machine washes only the lower rack, and glasses up top come out spotted and gritty while plates below look clean.
OWI sensor and end of cycle drying
JennAir uses an optical sensor to read water clarity and decide when the load is done. A fogged or failed OWI cuts the final heat and vent stage short, so the cycle finishes on time yet the top rack comes out dripping.
Drain pump and check valve at the sump
A dishwasher not draining usually traces to a pump impeller jammed with a shard of glass or a check valve that lets dirty water siphon back into the tub. We clear the sump, test the pump under load, and replace what is worn.
Filter assembly and sump screen
A clogged filter starves the wash pump, and the first signs are film on glassware and a sour smell when the door opens. We deep clean the sump, inspect the screen for damage, and reset the machine to full water flow.

Questions, answered
Before you call.
Do you repair JennAir dishwashers?
Diverter motor failure and OWI sensor faults that leave loads wet account for most of the JennAir dishwasher calls we run, and our factory trained technicians handle both weekly. Onyx Appliance Service is an independent company, not affiliated with or authorized by JennAir.
Why does my JennAir dishwasher leave the top rack wet?
Testing starts at the OWI sensor, the optical eye that tells the control when the load is clean and dry. When it misreads, the cycle ends before the heated dry completes. A failed diverter motor can add to it by starving the upper spray arm of hot water.
What does a JennAir dishwasher repair cost?
JennAir owners get one number from us, not a range that grows. The visit begins with a $95 diagnostic, waived with your repair, and you receive an exact quote before any work begins. One Quote. One Price. Guaranteed Repair. No Supplemental Estimates.
Do you use genuine JennAir parts?
Only genuine OEM parts matched to your model and serial number go into our repairs, never aftermarket substitutes. Common JennAir dishwasher parts, including diverter motors and sensors, ride on the truck, which is why most repairs finish in a single visit.
Is the repair covered by a warranty?
Before we leave, you receive the 3 Year Onyx Warranty in writing at the time of service. It covers parts and labor on the work performed, so if the same fault returns within the coverage period, the return visit costs you nothing.
