EHE — Heater drawing excessive current

EHE indicates the main board has detected abnormally high current draw on the heater circuit. The dryer shuts the heater down because excessive current can trip the house breaker, damage the relay, or pose a fire risk.

How to fix it

  1. Unplug the dryer immediately — do not keep retrying the cycle.
  2. Remove the rear/heater-box panel and inspect the element for visible short to ground.
  3. Measure element resistance to chassis with a multimeter — should be infinite; any reading to ground means replace the element.
  4. Inspect the heater harness from the element to the main board for melted insulation; repair or replace as needed.
  5. If element and wiring check good, suspect a welded heater relay on the main control board and replace the board.
  6. After repair, run a short Timed Dry and verify the breaker does not trip and EHE does not return.
