iE1 — Drain pump relay failure
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.

How to fix it
- Power-cycle the dishwasher at the breaker for 5 minutes.
- Remove the lower spray arm and filter; clear the sump of debris and broken glass.
- Disconnect the drain pump and spin the impeller by hand — it should move freely.
- Measure pump winding resistance (typically ~50-200 ohms; any short to ground = bad).
- Inspect the harness from board to pump for chafing or corrosion.
- Replace the drain pump if jammed or electrically faulty.
- Replace the control board if the relay is damaged.
Why it happens
Typical signs: 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
- Failed drain pump relay on control board Relay contacts welded or burned open.
- Shorted drain pump Pump windings shorted to ground draw high current and trip the protection.
- Jammed drain pump impeller Glass, label paper, or food debris locks the impeller and overloads the relay.
- Loose connector at the drain pump Intermittent contact creates arcing that degrades the relay.
