Dryer Error Codes By Brand
AF? E22? HE? No, they’re not football play calls. They’re actually dryer error codes. Each indicates something is wrong with your dryer. These codes can differ from brand to brand; we've got you covered whether you own a Samsung, LG, Electrolux, or something else. Below you’ll find brand-specific clothes dryer error codes often pointing to airflow restriction, lint buildup, overheating problems, and other risks that will compromise your home's safety. If your dryer shows one of these warnings, it’s best to prevent use until a professional inspects and cleans your vent system.

Stay Protected with Maintenance and Safety Tips
Understanding error codes is only half the battle. Regular maintenance and preventative care are the best ways to avoid dryer shutdowns and fire hazards. Even if your dryer isn’t currently displaying a code, clogged ducts and hidden blockages can still create dangerous conditions over time. Following these simple safety tips will keep your dryer running efficiently and your home's everyday routine protected.
- Cleaning Frequency: Have your vent and lint filter inspected and cleaned annually, or more often for large households, pet owners, or long vent runs.
- Hazards: Blockages aren’t just lint. Bird nests, snow, ice, or overgrown plants can all clog vents and ducts.
- Vent Length Rules: Dryer vents should be under 25 feet, minus deductions for each bend. Longer runs need booster fans.
Fabric Softeners and Lint Traps
While lint is the leading cause of dryer fires and other problems, fabric softener and dryer sheet residue can quietly cause problems. This sticky buildup coats lint traps, making them less effective and allowing more lint to bypass the lint filter and enter your vent line. Left untreated, it increases the risk of ruining your clothes, overheating, and even dryer fires in your home and other areas.
Some warning signs include:
- Sticky or slimy lint screen
- Damp laundry loads after a drying cycle
- Burnt odor near the dryer
Prevent these problems from happening by cleaning and washing your lint screen monthly with warm, soapy water, reducing the use of clothes dryer sheets, and getting your vents regularly cleaned to prevent dust, leaves, and other blockages.
Quick Reset Checklist
Sometimes an error code is temporary and can be cleared with a quick reset. However, if airflow issues are the underlying problem, the code will keep coming back. Use this tried and true reset process as a short-term check, but don’t rely on it as a permanent fix.
If your dryer throws an error code:
- Turn the dryer off or disconnect for 5–10 minutes.
- Check the lint trap, duct, drum, and other openings.
- Close the openings and start the dryer again.
- If the code returns, call Dryer Vent Wizard of South Seminole for cleaning and maintenance advice.
Master the No-Code Warning Signs
Not all dryers display error codes, but that doesn’t mean they’re problem-free. Your dryer may be speaking to you in other ways, and it’s important to recognize these warning signs before they escalate into bigger issues.
Watch for:
- Longer drying times.
- A hot dryer
- Burning smell.
- Lint is accumulating around the appliance and on the clothes after a load.
Don’t Wait for a Breakdown
Error codes are more than just numbers and letters on a screen; they’re your dryer’s way of speaking to you. When it flashes a warning about airflow, blockages, or overheating, it tells you something is wrong and that continuing to run the machine could be dangerous. Failure to notice these signals doesn’t just risk a costly repair; it can also lead to clothes dryer fires, excessive energy bills, or costly replacements to your home and appliance. Dryer Vent Wizard's simple tips ensure your safety and security when you cannot decode confusing error codes.
