Frigidaire Dishwasher Error Codes: Troubleshooting Guide

When your Frigidaire dishwasher displays an error code, it can be both puzzling and frustrating, especially when you need clean dishes quickly.

These codes are designed to help you identify specific problems with your appliance. Each code provides valuable diagnostic information that can help you solve the issue or determine when professional service is needed.

In this article, we’ll decode the most common Frigidaire dishwasher error codes, explain what causes them, and provide practical steps to resolve these issues, potentially saving you time and money.

Understanding Your Frigidaire Dishwasher Display

Frigidaire dishwashers communicate errors differently depending on your model. Newer models display numeric or alphanumeric codes on a digital screen, while older models may use flashing lights or beeping patterns. Before troubleshooting, locate your model number (usually found on the inside edge of the door) and consult your user manual for specific information about your dishwasher’s error notification system.

Common Frigidaire Dishwasher Error Codes

i10, i20, i30, i40, or iF0 (Water Supply Errors)

Problem Explanation

These codes indicate issues with water entering the dishwasher:

• i10: Water not entering fast enough
• i20: Water not detected in the tub
• i30: Drain system problem or leak detection
• i40: Flood protection activated
• iF0: Water filtration system issue

These problems typically stem from restricted water supply, kinked inlet hoses, clogged filters, or issues with the water inlet valve. Left unresolved, these errors can prevent proper cleaning and potentially damage the appliance.

Safety Considerations

Before investigating water supply issues, turn off the water supply to the dishwasher and disconnect power by unplugging the unit or turning off the circuit breaker.

Troubleshooting Steps

1. Check that the water supply valve under the sink is fully open.
2. Inspect the inlet hose for kinks or damage that might restrict water flow.
3. Remove and clean the dishwasher’s water inlet filter, located where the water supply line connects to the dishwasher.
4. Check for clogs in the dishwasher’s internal filter system at the bottom of the tub.
5. For i30 or i40 errors, look for signs of water leakage around the base and ensure the drain hose is properly positioned.

When to Call a Professional

Contact a service technician if the error persists after checking all water connections, if you detect a leak that continues after tightening connections, or if the water inlet valve needs replacement.

PF (Power Failure)

Problem Explanation

The PF error indicates that the dishwasher experienced a power failure or significant power fluctuation during operation. This isn’t necessarily a malfunction but rather the dishwasher informing you that a cycle was interrupted.

Troubleshooting Steps

1. Press the “Cancel” or “Start/Reset” button to clear the error code.
2. If the cycle was interrupted, consider running a rinse cycle to remove any detergent from dishes.
3. Check your home’s circuit breaker to ensure it hasn’t tripped.
4. If power fluctuations are common in your area, consider using a surge protector.

When to Call a Professional

Professional service is rarely needed for a PF error unless it occurs frequently without actual power outages.

ER, HO, or H0 (Heating Element Errors)

Problem Explanation

These codes indicate that the dishwasher is having difficulty heating water to the proper temperature. The heating element is crucial for effective cleaning and sanitizing. Problems with water heating can result in dishes that aren’t properly cleaned, especially with greasy residues.

Safety Considerations

The heating element can reach very high temperatures. Always ensure the dishwasher is unplugged and has completely cooled before attempting to inspect it.

Troubleshooting Steps

1. Check your home’s hot water supply by running the kitchen sink until the water becomes hot.
2. Run hot water at the kitchen sink for 30 seconds before starting the dishwasher.
3. Inspect the heating element (at the bottom of the tub) for visible damage or mineral buildup.
4. Test your home’s water temperature; it should be between 120°F and 150°F (49°C-66°C).

When to Call a Professional

Contact a technician if the heating element appears damaged, if scale buildup is severe, or if the error persists after ensuring proper hot water supply.

UO or UF (User Interface or Control Panel Errors)

Problem Explanation

These error codes indicate problems with the control panel or user interface system. Control panel issues can range from button malfunctions to complete system failures that prevent proper operation.

Troubleshooting Steps

1. Reset the dishwasher by disconnecting power for 2-3 minutes, then reconnecting.
2. Check for stuck buttons on the control panel.
3. Look for signs of moisture or water damage on the control panel.
4. Ensure nothing is pressing against the control panel when the door is closed.
5. Clean the control panel with a slightly damp cloth to remove any residue.

When to Call a Professional

Professional service is recommended if the control panel is visibly damaged, if there’s evidence of water behind the panel, or if the reset procedure doesn’t resolve the issue.

CE or CE+ (Communication Error)

Problem Explanation

This error indicates a communication breakdown between the dishwasher’s electronic components. These communication errors prevent proper coordination of functions, resulting in cycles that don’t complete properly.

Troubleshooting Steps

1. Perform a complete reset by disconnecting power for 5 minutes.
2. After reconnecting power, select and start a cycle to see if normal communication resumes.
3. Check for loose wire connections if you’re comfortable removing the lower access panel.
4. Look for signs of water damage that might be affecting electronic components.

When to Call a Professional

Communication errors typically require professional service, especially if they persist after a reset or if there’s evidence of water damage to electronic components.

Final Thoughts

While Frigidaire dishwasher error codes can be frustrating, they provide valuable information to help you identify and resolve issues quickly. Many problems can be fixed through simple troubleshooting steps without requiring professional service.

When DIY solutions don’t resolve the issue, don’t hesitate to contact a qualified technician who specializes in Frigidaire appliances.

Keep your Frigidaire dishwasher running smoothly and prevent error codes with these simple maintenance practices:

• Clean the filter at the bottom of the tub monthly to prevent clogs and water flow problems.
• Use a dishwasher cleaner once a month to remove buildup.
• Scrape large food particles off dishes before loading to prevent drain clogs.
• Regularly inspect the spray arms for food particles that might block water jets.
• Check door seals quarterly for damage or food debris that could cause leaks.
• Run hot water at your kitchen sink before starting the dishwasher.
