Frigidaire Dishwasher i50 Code: Causes & Fix

What is the Frigidaire Dishwasher i50 error?#

i50 means the wash motor — the circulation pump that drives water up through the spray arms — has failed on your Frigidaire dishwasher. The symptom is dishes that come out dirty because, even though the tub fills, no water is being forced through the sprayers. This one is mostly a technician job, but there is one quick thing worth checking before you assume the motor is dead.

i50 on a Frigidaire Dishwasher: likely causes and repair cost#

On a Frigidaire Dishwasher, the i50 code signals: wash motor failure.

Typical professional repair: $200–$400 · Difficulty: professional only · usually a technician job

Symptoms that often accompany i50: Dishwasher fills but does not spray; No water circulation sound; Dishes completely unwashed

Technician diagnostic sequence for i50:

1. Check sump for foreign objects jamming the impeller — glass shards and bones are common
2. Measure wash pump motor resistance — should read 5-40 ohms
3. Check wiring harness from control board to pump for burns or breaks
4. If pump hums but water does not spray, the impeller is jammed; silence = motor failure

Parts a technician may check or replace: wash pump assembly; main control board

Field note: Remove the fine filter and check the sump before condemning the motor. A piece of broken glass or a label blocking the impeller is a cheap fix vs full pump replacement.

Safety note: Disconnect power before accessing the sump or pump components — the pump runs on 120V AC.

How to troubleshoot the i50 error yourself#

Before writing off the wash motor, rule out a jam. Cut power at the breaker, remove the lower spray arm and the filter, and check the wash pump inlet for a shard of glass, a fruit pit, or a chunk of debris that can seize the impeller — clearing a jam occasionally revives a motor that only appeared dead. Also listen on a test cycle: a hum with no water movement points to a seized or electrically failed motor, while total silence points more to wiring or the control. That is about as far as safe DIY goes here. Confirming a burned-out wash motor means metering the windings under power, and replacing it means pulling the pump assembly from under the tub, so I hand i50 to a technician once the jam is ruled out.

Is the Frigidaire Dishwasher i50 error worth fixing?#

An i50 repair runs $200 to $400, since the wash motor is a substantial part and reaching it takes real labor. That is still well below the price of a new dishwasher, so on a machine that is otherwise in good shape the repair is worth it. Where I pause is an older unit near the end of its life — when a $200 to $400 motor lands on a dishwasher that is already tired, replacement starts to make sense, especially if it approaches half the cost of a new one after other niggles.

Frigidaire Dishwasher i50: frequently asked questions#

What does the i50 error mean on a Frigidaire dishwasher?#

i50 signals a wash motor failure — the circulation pump that pushes water through the spray arms is not working, so dishes do not get cleaned even though the tub fills.

Is it safe to keep using a Frigidaire dishwasher showing i50?#

There is no hazard, but it is pointless — without the wash motor the dishes will not come clean. It is best to stop and get it diagnosed.

Can I clear the i50 error myself?#

Only if a jam in the pump is the cause; clearing debris from the impeller occasionally helps. A truly failed wash motor requires a technician to test and replace.

How much does it cost to repair i50 on a Frigidaire dishwasher?#

A professional repair typically runs $200 to $400, reflecting the cost of the motor and the labor to reach it.

Which parts usually fail when a dishwasher throws i50?#

The wash pump motor is the primary failure, sometimes preceded by debris that seizes the impeller or by a wiring fault to the motor.

Why does a burned-out wash pump motor trigger the i50 error?#

The control watches the wash motor for proper operation. When the motor windings fail or seize, it draws the wrong current or does not turn, and the control reports i50.

Is a Frigidaire dishwasher with i50 worth repairing?#

On a sound machine, yes — a $200 to $400 repair beats a new dishwasher. On an old, tired unit, replacement can be the smarter call.
