Samsung DW90H89TETR Repair & Common Issues

The DW90H89TETR is a 24-inch built-in dishwasher that Samsung lists as Bespoke AI Smart Dishwasher AI Wash & 3rd Rack Washing System | AutoRelease™ Door 38dBA. Poor cleaning on the DW90H89TETR is worked through in order – filter, spray arms, water temperature at the machine, detergent and rinse aid – before the circulation pump is suspected, because most gritty-glass complaints resolve well before that.

With the breaker off and the supply valve under the sink closed, the toe-kick and outer door panel of the DW90H89TETR come off and the part a code names is measured rather than swapped; AP on the display, which means app-pairing mode, is explained and not treated as a problem.

FAQ

Samsung DW90H89TETR FAQ

LC or LE is the leak-sensor code: moisture has reached the sensor in the base of the DW90H89TETR. With the breaker off and the supply valve closed, look for water on the floor beneath the DW90H89TETR 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.

Once the DW90H89TETR is switched off at the breaker and the water inside has cooled, lift out the filter assembly at the bottom of the tub the way the manual shows, rinse it and look into the sump beneath for food or glass. Check that the drain hose under the sink is not kinked and that the disposer knockout was removed if the hose connects there. If water still stands with a clean filter and a clear hose, the drain pump or the sump check valve needs testing.
