Unusual smell

After finishing any service: (1) Check door lock switch operation — must lock during run, stop when unlocked, (2) Verify authentic Samsung parts used, (3) Check all wires — not loose or tight, correct connections, bound with tape, properly clamped, (4) Check all screws/nuts fastened to spec torque, (5) Remove all foreign material from inside tub and sump (check through disposer), (6) Check for water leakage from all connections — hose connectors, door, case sump, drain/circulation motor, heater, thermistor, turbidity sensor, distributor motor, water supply/drain hoses, (7) Check power cable and outlet voltages, (8) Verify dishwasher is level, (9) Check installation is on flat/stable surface.

For models with a vane (like the DW80K7050), the vane must always be positioned at parking when the bottom nozzle starts spraying. Failure to park the vane will cause water leakage. This is critical during both normal operation and Smart Install service mode testing.

When removing the water valve hose clamp, take care to hold it tightly. The clamp is under tension and if released, it can become a projectile and cause injury. There will also be residual water in the valve and valve hose — use a towel.

The thermistor, pump-drain, and sensor-turbidity all have seals. When reinstalling these components, make sure the seal is properly seated to prevent water leakage. A misaligned seal will cause slow leaks that eventually trigger the LC leakage error.
