Frigidaire Dishwasher Error Code ER-03 — Wash Motor Malfunction
What this means
Error code ER-03 indicates the wash motor (circulation pump motor) is not operating correctly. The motor may be physically jammed by debris, have failed bearings, or the motor windings may have burned out. Water will not be circulated through the spray arms.
Step-by-step fix
4 stepsClear debris from the sump
Remove the lower spray arm, filter assembly, and sump cover. Remove any debris like broken glass, food particles, or plastic that may be jamming the motor impeller.
Broken glass from a cracked dish is a common cause of wash motor jams.
Check the wash motor impeller
With the sump cleared, try to spin the wash motor impeller by hand. It should rotate smoothly.
A grinding sound when spinning indicates worn bearings inside the motor.
Test the wash motor
Use a multimeter to check the motor windings for proper resistance and no short to ground.
A typical wash motor reads between 3–10 ohms across its terminals.
Replace the wash motor
If the motor has failed, remove the dishwasher from under the counter, lay it on its back, disconnect the motor, and install the replacement.
The wash motor is accessed from underneath the dishwasher — you'll need to lay the unit down.
When to call a professional
Wash motor replacement involves removing the dishwasher and working underneath. Call a pro if you're not comfortable with this.
