Last updated: October 6, 2026

- Failing circulation (wash) pump
- Wiring short in the pump circuit
- Power surge damaging the board's pump driver
How to fix Frigidaire I50 — step by step
Work through these in order, from simplest and safest first. Stop as soon as the code clears.
- Power-reset at the breaker
Turn off the dishwasher's circuit breaker for 5 minutes, then turn it back on and try a cycle. A glitch can rarely mimic this fault, but a true shorted triac brings I50 straight back. - Listen for the symptom
Start a cycle and listen. A wash pump roaring at full speed from the very start, followed by the cycle stopping with I50, confirms the uncontrolled-pump symptom. - Call a technician for board or pump replacement
I50 is a board-level electronic fault: the pump driver triac on the control board has shorted. Confirming it and replacing the board (or the pump, if the pump caused the short) is technician work.Safety warning: Do not attempt to repair the control board yourself. Board-level faults involve line voltage and water in close proximity.
When to call a technician
- I50 returns after a power reset
- The wash pump roars at full speed then the cycle stops
- The control board's pump driver needs replacement
- The circulation pump itself needs testing
Frequently asked questions
Circulation pump vs drain pump: which one is I50 about?
The circulation pump washes the dishes by spraying water. The drain pump only removes water at the end. I50 is about the wash pump running out of control.
What is a triac?
The triac is a tiny electronic switch soldered onto the control board. When it shorts, the pump gets full power with no speed control.
Can I still run the dishwasher with I50?
No. With the pump running uncontrolled, the control stops the cycle to prevent damage. The dishwasher will not wash properly until this is fixed.
