Frigidaire Dishwasher Error Code i50 — Drain Pump Circuit Fault
What this means
The i50 error on Frigidaire dishwashers indicates the drain pump circuit is not functioning correctly. The control board detects that the drain pump is drawing too much current (possibly jammed) or no current at all (motor failure or wiring issue). Common causes include debris in the drain pump, a failed pump motor, or a loose wire connector.
Alternate codes: I50
Step-by-step fix
4 stepsClean the drain filter and sump
Open the dishwasher and remove the lower rack. Remove the drain filter and clean all food debris from the sump area. Check for glass, bones, or other hard objects that could jam the drain pump.
Clean the filter under running water with a soft brush — avoid using sharp objects that could damage the mesh.
Check the drain pump impeller
With the filter removed, look into the drain pump area. Try spinning the impeller with your finger — it should rotate freely. If it is jammed, clear the obstruction.
Small fruit pit fragments and broken glass are common drain pump blockers.
Test the drain pump motor
Disconnect power. Access the drain pump from below the dishwasher. Disconnect the pump wires and test for continuity. A good pump motor will show some resistance. An open reading means the motor has failed.
Check the pump connector for signs of water damage or corrosion.
Replace the drain pump if faulty
Remove the old drain pump (usually held by a twist-lock or screws), disconnect the drain hose, and install the new pump. Reconnect the wiring and hose.
After replacing, run a rinse cycle to test draining before running a full wash.
When to call a professional
If the pump tests fine but i50 persists, the control board's pump relay may be defective — professional board-level diagnosis is needed.
