Samsung DW80CG5450 / DW80CG5420 StormWash dishwasher: quick sheet

Covers: Samsung 24-inch top-control DW80CG5450SR (stainless) and DW80CG5450MT (black stainless), with the DW80CG542***** sibling (14 place settings, no third rack). ENERGY STAR lists both DW80CG542***** and DW80CG545***** on the market from July 2023 (C = 2023). Canadian version: DW80CG5450SRAA.

Current entry-to-mid Samsung dishwasher: StormWash high-pressure jet, AutoRelease door dry, third rack (on 545x), top hidden controls, 46 dBA. Same fault logic as other Samsung DW80 dishwashers: 4C/4E water supply, 5C/5E drain, LC/LE leak, HE/HC heater. Deep diagnostics: see the Samsung dishwasher field service manual.

Safety first

  • Switch off the circuit and shut the water before removing the kick plate or pulling the unit.
  • Water in the sump may be hot right after a cycle.
  • Live-voltage checks at the valve, pump or board are caution work.
  • Watch for broken glass in the filter and pump.

How it works

The inlet valve fills the sump; a circulation (wash) pump feeds the spray arms and the StormWash jet. A heater warms the water (one retailer lists 1,200 W) and a temperature sensor reports to the board.

Water drains through a filter in the tub floor to a small drain pump (one retailer lists about 35 W). A leak sensor in the base pan stops the cycle and shows LC/LE when water collects there.

AutoRelease dry pops the door open at the end of the cycle so steam escapes; Heated Dry can be added as an option.

Soil sensing (listed by ENERGY STAR) lets the Auto cycle adjust water and time.

Diagnostic guides for this appliance

Guide · Dishwasher

Dishwasher detergent dispenser won't open (detergent left in the cup)

First rule out blocking dishes, caked detergent and an unfinished cycle. Then test the dispenser actuator (a wax motor or bimetal/solenoid on most units) for an open circuit, and check whether the control sends 120 V to it during the wash. A cup that opens but leaves detergent behind is a wash problem, not a dispenser problem.

Gritty or sandy residue on dishes after washing

Grit is usually redeposited soil: a clogged filter, a drain that cannot clear (air gap, disposer, hose) or detergent that did not dissolve. Hard water causes white film rather than grit. Work from the filter outward, then check the drain path and the wash motor.

Dishwasher completely dead: no lights, no response (supply, door switch, thermal fuse)

Prove supply voltage at the junction box with a meter before blaming any part. Then check the door switch circuit and, on units that have one, the one-time thermal fuse near the control. Replace the control board only after these pass.
