Frigidaire Dishwasher i50 — What It Means & How to Fix It
The control board has flagged a problem driving the wash motor — the circulation pump that powers the spray arms — and because that's a mains-voltage motor sealed under the tub, it's a repair for a technician.
What this code means
i50 means the control can't get the wash motor to behave as commanded: it may not start, may run when it should be off, or may draw wrongly because of a winding or wiring fault. That motor is the circulation pump that drives water up through the spray arms, and it lives on mains voltage in the sealed base of the machine. One power reset is worth trying for a fluke reading, but a persistent i50 is hardware.
i50 isn't on Frigidaire's current published code list, so confirm it against your model's tech sheet; independent repair sources consistently tie it to the wash/circulation motor and its control circuit. The diagnosis runs on live-voltage and resistance testing that belongs with a technician.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Wash (circulation) motor failure — windings or bearings | Common | No — technician job |
| Wiring or connector fault between control board and motor | Common | No — technician job |
| Control board not driving the motor correctly | Occasional | No — technician job |
| One-off control glitch after a power event | Less common | Yes — power reset only |
What you can try yourself
- Switch the dishwasher off at the breaker for five minutes, restore power, and run a short cycle — this clears the code if it was a one-time glitch.
- Check that the filter and spray arms are clear and the arms spin freely, ruling out a simple obstruction before the visit; go no further into the machine than that.
- If i50 returns, take the dishwasher out of use and book a repair — the motor, its wiring, and the control board are all mains-voltage parts in the sealed base.
- Tell the technician what you noticed — a silent wash, an unusual hum, or the motor running oddly — to point them straight at the circuit.
When to call a technician
- A repeat i50 after the power reset — that's the cue to call rather than keep retrying.
- The wash runs silent, or the motor hums without water moving through the arms.
- A scorched smell or the breaker tripping during a run: kill the power and leave it for the technician.
Typical professional repair cost: A wash/circulation motor or pump replacement typically runs $200–$400 with labor; a control board can reach $250–$400.
Frequently asked questions
Can I fix a Frigidaire i50 error myself?
Beyond a single power reset and checking the spray arms and filter are clear, no. i50 points at the wash motor and its control circuit — mains-voltage parts in the sealed base whose diagnosis needs live-voltage testing. That's a technician's job, both for safety and to avoid swapping the wrong part.
What does the wash motor do on a dishwasher?
It's the circulation pump that pressurizes and throws water up through the spray arms to clean the dishes — separate from the drain pump that empties the tub. When i50 flags it, you'll usually get poor or no cleaning because the water isn't being circulated.
Is an i50 repair worth it?
It depends on the machine's age and the quote. A circulation-motor or control-board repair can run a few hundred dollars, so on an older unit it's worth weighing against replacement. A technician's diagnosis tells you which part has actually failed before you decide.
