Frigidaire Dishwasher iE1 — Drain pump relay failure

Frigidaire Dishwasher · Error code iE1

What iE1 Means

The control board detected a fault in the drain pump relay circuit. The dishwasher cannot reliably command the drain pump, so cycles abort and water may be left in the tub.

Symptoms

  • Standing water in the tub at end of cycle
  • Drain pump doesn't run or won't stop
  • iE1 displayed with cycle abort
  • Repeated cancel/drain sequence fails

Common Causes

1
Failed drain pump relay on control board

Relay contacts welded or burned open.

2
Shorted drain pump

Pump windings shorted to ground draw high current and trip the protection.

3
Jammed drain pump impeller

Glass, label paper, or food debris locks the impeller and overloads the relay.

4
Loose connector at the drain pump

Intermittent contact creates arcing that degrades the relay.

How to Fix It

  1. Power-cycle the dishwasher at the breaker for 5 minutes.
  2. Remove the lower spray arm and filter; clear the sump of debris and broken glass.
  3. Disconnect the drain pump and spin the impeller by hand — it should move freely.
  4. Measure pump winding resistance (typically ~50-200 ohms; any short to ground = bad).
  5. Inspect the harness from board to pump for chafing or corrosion.
  6. Replace the drain pump if jammed or electrically faulty.
  7. Replace the control board if the relay is damaged.
