Replace the dishwasher heating element (exposed loop type)

Exposed loop elements sit in the bottom of the tub and are held by plastic nuts or clips under the tub. The unit usually has to come out of the opening. Prove the supply water is hot and check the high-limit, then swap the element, tighten the plastic nuts only snug, leak-test with water in the tub, and run a cycle. Many Bosch and some other designs use an in-line heater pump instead: different procedure.

Before you start

  • Turn off the breaker and verify 0 V at the junction box before disconnecting wiring.
  • Close the hot-water stop and disconnect the supply into a pan before pulling the unit out.
  • Let the element cool if the unit just ran; it can be hot enough to burn.

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.
