Frigidaire Dishwasher iE0 — Wash motor relay failure

Frigidaire Dishwasher · Error code iE0

What iE0 Means

The control board detected a fault in the wash motor relay circuit. The board can no longer reliably switch the circulation (wash) pump on and off, which usually halts the cycle.

Symptoms

  • Cycle stops mid-wash and shows iE0
  • Wash pump fails to start when it should
  • Wash pump runs continuously and won't shut off
  • Dishwasher beeps and flashes iE0 after start

Common Causes

1
Failed wash motor relay on control board

The relay contacts welded shut or burned open from years of switching the pump.

2
Shorted or seized circulation (wash) pump

A pump with shorted windings or a jammed impeller draws excess current and damages the relay.

3
Loose or corroded wiring at the pump

Bad connection causes voltage drops or arcing that confuse the board feedback.

4
Moisture intrusion on the control board

A leaking door gasket or steam ingress can corrode the relay area.

How to Fix It

  1. Cut power at the breaker for 5 minutes to attempt a reset.
  2. Pull the dishwasher out and inspect the bottom for water damage or rodent intrusion.
  3. Open the control board housing and inspect the wash motor relay for burn marks or a swollen body.
  4. With power off, check the circulation pump windings for resistance to ground (any continuity = bad pump).
  5. Verify wiring from the board to the pump is tight and uncorroded.
  6. Replace the control board if the relay is visibly damaged but the pump tests good.
  7. Replace the wash pump motor if it's shorted or seized — and replace the board if it took the relay with it.
