Dryer error codes can be confusing, but they’re your appliance’s way of telling you something’s wrong. Whether it’s a blocked vent, faulty sensor, or control board issue, understanding the code is the first step to a quick solution. In this guide, we break down the most common dryer error codes and explain exactly what they mean. You’ll also find step-by-step solutions to help you troubleshoot or know when it’s time to call a professional. Book our dryer repair service:

Vent Blockage
Possible codes:
Clg / Cg – clog detected
D80 – 80% airflow restriction
D90 – 90% airflow restriction
D95 – 95% airflow restriction (critical)codes:
The ventilation problem often occurs due to lint buildup or other blockages in the exhaust system.
Solution
- It’s necessary to completely remove lint from the lint filter, which is usually located at the door or on top.
- Next, clean the flexible hose or pipe connecting the dryer to the vent opening. If needed, disconnect and shake it out.
- Be sure to clean the external vent cover outside the house — it may be blocked by dust, leaves, or insects.
- Inspect the back of the dryer where the air exits into the duct, and make sure there is no clog. If the vent run is long, use a flexible brush on a long handle or a vacuum with a special attachment to clean it.
- After cleaning, restart the dryer and check if the code has disappeared.
Heating Element or Temperature Sensor Faults
Possible codes:
F03 – thermistor fault
F08 – overheating
E1 / E2 – temperature sensor error (incorrect resistance)
Solution
- First, unplug the dryer.
- Using a multimeter, check the heating element for continuity — it should have resistance (usually 10–50 ohms). If the circuit is open (infinite resistance), the element needs to be replaced.
- Also check the thermistor (temperature sensor), which should give stable resistance (usually around 10kΩ at room temperature). A large deviation indicates a fault.
- Clean the inside of the dryer from lint buildup, as it may cause overheating.
- Make sure the thermal fuses are not blown (they also need to be replaced if the circuit is open).
- After replacing faulty components — restart the dryer and check the result. If the code remains, also inspect wiring and connectors.
Motor Circuit Faults
Possible codes:
F02 – motor drive circuit error
Electrical faults in the motor circuit may prevent the drum from spinning.
Solution
- Unplug the dryer from the power outlet.
- Remove the back or bottom panel to access the motor.
- Make sure the drum belt is not broken and is in place.
- Check for any mechanical obstructions inside the drum or motor (for example, foreign objects or trapped lint).
- Use a multimeter to check the motor windings for resistance – if the circuit is open or there’s a short, the motor should be replaced.
- Inspect terminals and wiring: overheating or oxidation of contacts is possible.
- Sometimes F02 can be triggered by a fault in the control board — in this case, inspect the board’s connection to the motor.
- After resolving the issue, turn the dryer back on and check the result.
Door Lock Faults
Possible codes:
F06 – door lock error
This error indicates a faulty door lock, preventing the dryer from starting or completing a cycle.
Solution
- First, make sure the door is tightly closed and nothing is interfering with the lock.
- Unplug the dryer.
- Check the door switch or latch: if it’s physically damaged or doesn’t latch, it needs to be replaced.
- Use a multimeter to check for continuity — when the door is closed, the contacts should close. If the lock doesn’t send a signal to the control board, the dryer won’t start.
- Inspect connectors and wiring leading to the lock. Connectors may be loose or oxidized. Clean and reconnect.
- If the door lock is working but the error persists — check the control board, especially the part responsible for door locking.
- After fixing the issue, restart the dryer and make sure the error code is gone.
Electronic Control Board Faults
Possible codes:
F01 – main control board failure
F07 – internal microprocessor error
F01 or F07 usually indicate a microchip or relay failure on the main control board.
Solution
- Unplug the dryer for at least 10 minutes — this may reset the error.
- If the code returns, remove the back or top cover to access the board. Inspect it for burnt traces, swollen capacitors, or burned relays. If there is visible damage — the board needs replacement.
- Sometimes re-soldering the connectors helps, but this requires caution.
- Check the incoming power (especially if there was a power surge) and grounding.
- Be sure to test all connections between the board and key components (motor, heater, lock).
- If the error reappears after replacing the board — contact the manufacturer or a certified technician to rule out other faults.

My Bosch dryer is showing error E17. What does it mean?
Hi Michael! Error E17 on a Bosch dryer usually indicates an issue with the temperature sensor or the heating element. It could be caused by a faulty thermostat, overheating, or a problem in the heating circuit. We recommend unplugging the dryer, checking and cleaning the ventilation system. If the error persists, it’s best to contact a qualified technician for diagnosis and repair.
What should I do if my Samsung dryer shows the HE error?
Hi William! The HE error on a Samsung dryer means there is a heating problem—most often related to a faulty heating element, thermostat, or clogged vent. First, try unplugging the dryer for 10 minutes to reset the error. Clean the lint filter and ventilation ducts thoroughly. If the error comes back, repair or replacement of the heating element may be needed, so it’s best to call a professional.
My Miele dryer is showing multiple errors — F12 and F13. Do you know how to fix this?
Hi Ryan! Errors F12 and F13 on a Miele dryer usually point to motor and ventilation issues. This often happens because the vent duct or fan is clogged, causing the motor to overload. We recommend cleaning the lint filters and ventilation from lint and dust first. If the errors persist, the motor or fan parts may need to be checked and possibly replaced. We’re here to help—our technicians can quickly diagnose and professionally repair your dryer. Contact us to schedule a service appointment!
