Samsung DW90F89T0USR Repair & Common Issues

The DW90F89T0USR is a 24-inch built-in dishwasher that Samsung lists as Bespoke AI Smart Dishwasher AI Wash & 3rd Rack Wash System | AutoRelease™ Door 38dBA. A DW90F89T0USR 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 DW90F89T0USR 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 DW90F89T0USR FAQ

LC or LE is the leak-sensor code: moisture has reached the sensor in the base of the DW90F89T0USR. With the breaker off and the supply valve closed, look for water on the floor beneath the DW90F89T0USR 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.

Rarely as a first cause. With the DW90F89T0USR switched off and cool, clean the filter, pull the upper spray arm and clear its holes, and check that the hot water at the nearest faucet is actually hot before the cycle starts. If the top rack is still gritty after that, the circulation pump and the upper-arm feed are what a technician tests.
