How to fix it

  1. Power off at the breaker and remove the kickplate.
  2. Pull both heater terminals at the bottom of the tub and ohm-test the element (typical 15-30 ohms).
  3. Inspect terminals for corrosion or burning; clean or replace as needed.
  4. If the element is open or shorted, replace it with the gasket.
  5. If the element tests good, suspect the ACU heater relay — replace the ACU.
