What the F8 error code actually means

Your SANGIORGIO dryer has detected a problem with the sensor that measures how wet your clothes are during the cycle. This sensor helps the dryer know when your laundry is dry enough to stop automatically. Try switching the dryer off completely and restarting it, as this can sometimes clear the fault if it was a temporary glitch.

Questions people ask about F8

What does F8 mean on a SANGIORGIO dryer?
The F8 code on a SANGIORGIO dryer indicates a fault with the humidity control sensor, which is the component that monitors moisture levels in your laundry during the drying cycle. The control board has detected that the sensor signal is abnormal, missing, or outside the expected range. This prevents the dryer from accurately determining when your clothes are dry. The fault can be caused by dirty sensor bars, wiring issues, or a failed sensor.
How do I fix the F8 error on my SANGIORGIO dryer?
Start by switching the dryer off and restarting it to see if the code clears. If it returns, open the dryer door and locate the two metal sensor bars inside the drum, usually near the front below the door seal. Clean them thoroughly with a cloth dampened with isopropyl alcohol to remove any residue. If cleaning does not resolve the fault, the wiring connections to the sensor and the sensor assembly itself will need to be inspected and potentially replaced.
How much does it cost to repair an F8 error on a SANGIORGIO dryer?
If the issue is simply dirty sensor bars, the repair costs nothing beyond a small amount of isopropyl alcohol. If the humidity sensor assembly needs to be replaced, parts and labor combined could range from around 60 to 150 dollars depending on part availability and local labor rates. If the main control board is ultimately found to be at fault, repair costs are typically higher, often in the range of 150 to 350 dollars, and it may be worth comparing that cost against the age and value of the appliance.
Will resetting the dryer clear the F8 error code?
Turning the programme rotary knob to the OFF position and restarting the dryer is the first recommended step and can clear the code if the fault was a temporary signal glitch. However, if the underlying cause is a contaminated sensor, damaged wiring, or a failed component, the F8 code will return once the dryer attempts to run a new cycle. A successful reset that holds indicates the fault was transient, while a recurring code requires hands-on diagnosis.
Is it safe to use my SANGIORGIO dryer when the F8 code is showing?
Running the dryer with an active F8 fault is not recommended. When the humidity sensor is not functioning correctly, the dryer cannot reliably detect when your laundry has reached the correct dryness level. This could result in the dryer running for an excessive amount of time, leading to over-drying of fabrics or unnecessary energy consumption. It is best to resolve the fault before resuming normal use.
