What you’ll find in this service repair guide
Are you seeing an "EC" error code on your Frigidaire dehumidifier, and you are not sure what it means? This guide will help you understand what’s behind this code, why it appears, and how to troubleshoot the issue to get your dehumidifier working again.
What Is the EC Code?
The EC code signals an issue within your dehumidifier’s sealed system. This part of the appliance is essential for removing moisture from the air, and it consists of key components like the compressor, condenser coils, evaporator, and refrigerant. When the EC code appears, it often points to a problem with the refrigerant level, coil blockage, or a system leak.
Table: Common Dehumidifier Error Codes and Solutions
| Error Code | Meaning | Possible Causes | Solution |
|---|---|---|---|
| EC | Sealed System Issue | Low refrigerant, coil blockage | Clean coils, check for refrigerant leaks, reset |
| E1 | Humidity Sensor Error | Faulty sensor, wiring issue | Replace sensor or wiring |
| E2 | Water Tank Full | Tank is full or not properly placed | Empty or reposition tank |
| DF | Defrost Mode Active | Low ambient temperature | Allow defrost cycle to complete |

Why EC Code May Appear on Your Frigidaire Dehumidifier
A few common issues can trigger the EC code on a Frigidaire dehumidifier:
- Dirty or Blocked Condenser Coils: Dust, pet hair, and other debris can block the condenser coils, impacting airflow and reducing efficiency. In severe cases, this can lead to overheating or system shutdown.
- Low Refrigerant Levels: If refrigerant levels drop, it could be due to a leak in the system. This is often caused by damaged seals or wear over time. Please see our table of signs of a refrigerant leak in dehumidifiers:
| Sign | Description |
|---|---|
| Sweet Odor | Often described as a faint, sweet chemical smell |
| Excessive Moisture | Damp spots may form around the dehumidifier |
| Hissing Sound | Indicates a possible leak in the refrigerant line |
| Decreased Efficiency | Appliance struggles to maintain humidity levels |
- Frozen Coils: Coils can freeze if refrigerant is low or the system is unable to dissipate heat effectively.
How to Troubleshoot the EC Code on Your Dehumidifier
When you see the EC code, try the following steps to identify and resolve the issue:
- Clean the Coils and Filter: Begin by cleaning any visible parts. Turn off and unplug the dehumidifier, then remove the filter and wipe down the condenser coils. Keeping these parts clean helps reduce strain on the sealed system.
- Reset the Dehumidifier: Resetting the unit can sometimes resolve a temporary error. Unplug the appliance, wait for at least 30 minutes, and plug it back in. This can reset the system and clear minor issues.
- Check for a Refrigerant Leak: If the problem persists, look for signs of a refrigerant leak, such as a sweet odour or damp spots. If you notice these signs, discontinue use and contact a repair specialist, as handling refrigerant requires certified expertise.
- Inspect the Water Bucket: Check the water bucket to see if the dehumidifier has stopped working. Clean it if it’s dirty or blocked to ensure the dehumidifier can continue operating smoothly. Empty the bucket, rinse it with mild soap and warm water, and wipe it dry before reinserting.
Some recommended maintenance tasks from our table can help the EC code not repeat again:
Table: Dehumidifier Maintenance Schedule
| Maintenance Task | Frequency | Steps |
|---|---|---|
| Clean Air Filter | Every 2-4 weeks | Remove and wash with mild soap; air dry before reinstalling |
| Empty Water Tank | After each use | Empty tank, rinse with warm water, and dry thoroughly |
| Inspect Coils | Every 6 months | Check for dirt or frost; clean if necessary |
| Check for Leaks | Annually | Inspect tubing and seals for any signs of leaks |

Tips to Prevent Future EC Errors
Keep your dehumidifier running smoothly with these simple maintenance tips:
- Clean the Filter and Coils regularly: A quick vacuum or wipe-down of these components monthly can make a big difference in performance.
- Ensure Proper Ventilation: Place your dehumidifier at least a few inches away from walls or corners to allow for adequate airflow.
- Check Warranty Options: The manufacturer may cover a professional repair if your dehumidifier is still under warranty.
Remember to choose the correct dehumidifier size for your space. A properly sized dehumidifier will operate efficiently without overloading, reducing the risk of error codes and mechanical issues:
Table 3: Choosing the Right Dehumidifier Capacity
| Room Size | Ideal Humidity Level | Dehumidifier Capacity |
|---|---|---|
| Small Room (up to 300 sq ft) | 30-50% | 10-20 pints |
| Medium Room (300-500 sq ft) | 30-50% | 20-30 pints |
| Large Room (500-800 sq ft) | 30-50% | 30-50 pints |
| Basement/Very Damp Area | 40-60% | 50+ pints |
