Samsung DW90F89P0USR Repair & Common Issues

Samsung’s page for the DW90F89P0USR reads Bespoke AI Smart Dishwasher AI Wash & 3rd Rack Wash System | AutoRelease™ Door 38dBA; like every dishwasher Samsung sells in the US it is a 24-inch built-in. A DW90F89P0USR that leaves water in the tub is traced from the filter to the pump to the drain hose, and a leak-sensor code on it is confirmed as a real leak or a false one – a spill that reached the base, or condensation – before anything is ordered.

We check hot-water temperature at the DW90F89P0USR on every poor-cleaning call, because a 4C or a filmy load on this model is often the supply and not the dishwasher.

FAQ

Samsung DW90F89P0USR FAQ

The same family - water supply - but different wording and different parts. On the DW90F89P0USR 4C or 4E points at water pressure or temperature too low for the cycle, so the first checks are the supply valve under the sink and the hot-water temperature reaching the machine, not the dishwasher’s own valve.

LC or LE is the leak-sensor code: moisture has reached the sensor in the base of the DW90F89P0USR. With the breaker off and the supply valve closed, look for water on the floor beneath the DW90F89P0USR and at the toe-kick. If the base is dry and the code returns once it has dried out, the sensor and its connections need testing rather than a hose.
