Troubleshooting a dishwasher error code can be frustrating but with the right guidance, fixable. One common issue owners of Frigidaire dishwashers encounter is the dreaded i50 error code. But don’t despair! This article provides a simple, 5-step process to clear the i50 error. From checking electrical connections to observing motor operation to testing winding resistance, following these troubleshooting steps will help diagnose what’s causing the issue. With some basic repairs or a small replacement part, you can have your dishwasher back to fully washing clean dishes again.
What Does the i50 Error Code on a Frigidaire Dishwasher Mean?
Seeing an i50 error code flash on your Frigidaire dishwasher display can be confusing. But don’t worry – this article will explain what it means and how to fix it.
The Circulation Pump
The circulation pump is the most important part of your dishwasher. It pumps and circulates water during the wash cycles to clean your dishes.
What the i50 Code Means
When an i50 shows up, it usually means the control board sees a problem with the circulation pump motor. Here are some of the issues that can cause an i50 error:
- The motor won’t turn on at all
- The motor runs even when it should be off
- There’s a loose wire or bad connection
- A short circuit fried something
- The motor windings are damaged
- Something is stuck in the pump impeller
Safety Precautions
When doing any appliance repair or maintenance, following proper safety procedures is crucial. Being safe will help prevent accidents, injuries, and damage.
Power Off and Unplug
The first rule is always to power off and unplug your dishwasher before doing any work. This applies to all appliances. Make sure to unplug the unit from the electrical outlet. If it’s hardwired, turn off the circuit breaker for the dishwasher circuit. Without power, you eliminate the risk of electrical shock.
Avoid Live Voltage Testing
Never test live voltage with a multimeter if you are not familiar with how to prevent short circuits. Accidentally touching the probes together while set to voltage mode can cause sparks, damage, or injury. Only test live circuits if you have proper training. Otherwise, always double-check that the power is off first.
Turn Off the Water Supply
Before starting dishwasher repairs, turn off the water supply at the shutoff valve. This prevents leaks and water damage if a hose comes loose. Locate the water supply lines behind or under the dishwasher and turn the valves clockwise to shut them off.
Allow the Unit to Cool
If the dishwasher has been recently used, give it plenty of time to cool down before working on it. The interior can get very hot from normal operation. Let it cool to room temperature to avoid burns.
Work in a Well-Lit Area
Make sure to work in a well-lit area so you can clearly see appliance parts and connections. Good lighting helps prevent mistakes or overlooking damage. Use a flashlight to inspect darker spots if needed.
Keep Work Area Clear
Keep your workspace free of clutter and objects that could get in the way. Remove rugs and cover sharp table edges. Keep children and pets away from the work area to avoid distractions or accidents.
Keep Hands Dry
Never work on internal parts with wet hands, as this risks electric shock. Make sure the dishwasher interior and your work area are completely dry before doing repairs. Even small amounts of moisture can cause issues.
Consult Manuals
Always check the user manual and service manual for your specific dishwasher model before doing repairs. There may be important notes about installation or component locations. Following proper procedures prevents mistakes.
Handle Parts Gently
When removing or installing parts, be very gentle. Excessive force can damage the appliance or cause personal injury from sharp edges. Take your time, and don’t rush.
How to Troubleshoot the i50 Error Code
When an i50 error code appears on your Frigidaire dishwasher, it means there is likely an issue with the circulation pump or wash motor. Here are some steps to diagnose and fix the problem.
Step 1: Check Electrical Connections
The first thing to check is the wiring harness that connects the control board to the wash motor.
- Unplug the dishwasher before inspecting any electrical parts. Safety first!
- Look for damage to the wiring harness. Replace it if damaged.
- Make sure the harness connector is firmly plugged into the control board. Wiggle it to confirm it’s seated properly.
- Inspect each pin on the connector for corrosion, dirt, damage or bends. Gently clean with electrical contact cleaner if needed.
- Use a multimeter to check the resistance on each wire leading to the motor. Refer to the service manual for correct readings.
Step 2: Check Voltage
Once connections are verified, it’s time to power up and check the voltage.
- Plug in and turn on the dishwasher.
- Start a test cycle.
- Carefully monitor the voltage at the motor wires with a multimeter while the machine runs.
- Check that the voltage on all power input pins matches the service manual.
Use extreme caution when testing live voltage!
Step 3: Verify Motor Operation
With power applied, observe if the motor is working correctly:
- Listen for the startup sound when a cycle begins. No noise could mean a bad motor.
- Feel for vibration on the motor housing while running. Little or excessive vibration can indicate issues.
- Turn off the dishwasher. If the motor continues running, there is likely a short circuit problem in the control board that requires replacement.
Step 4: Inspect Motor Parts
If electrical checks are normal, take a closer look at the motor itself:
- Manually turn the motor shaft to feel for rough spots or grinding.
- Inspect the windings for burned or damaged insulation.
- Check the housing, gaskets, and mounts for cracks or degradation.
Step 5: Check Winding Resistance
The final test is to measure motor winding resistance:
- Unplug and disconnect motor wires.
- Use a multimeter to measure the resistance across each winding. Consult the wiring diagram.
- Compare readings to service manual specs. The 3-winding motor should measure 56 Ohms across pairs.
- If the resistance is incorrect, the motor needs replacement.
With these troubleshooting steps, you should be able to diagnose an i50 error code and get your Frigidaire dishwasher washing again!

Wrap Up
If you are seeing an i50 error code on your Frigidaire dishwasher, don’t panic! In most cases, the problem is with the circulation pump motor. By methodically troubleshooting the electrical connections, voltage, motor operation, and internal windings, you can diagnose the issue.
The key steps are:
- Check all wiring and connections leading to the motor
- Verify proper voltage is applied during a cycle
- Observe if the motor is starting and running correctly
- Inspect the motor windings and internal parts
- Test the winding resistances with a multimeter
Following basic safety precautions is also very important when doing any appliance repair work. Make sure to power off, avoid live voltage testing, and refer to manuals.
With some patience and the right tools, many homeowners can successfully troubleshoot an i50 error on their Frigidaire dishwasher. If needed, don’t hesitate to call in a service technician. But hopefully these tips will get your machine washing dishes again in no time!
