Symptoms
• Dryer stops mid-cycle and displays F02 error code on the control panel
• Dryer will not start or begin a cycle
• Clothes remain wet or damp after the cycle completes
• Dryer runs continuously without auto-shutoff
• Control panel becomes unresponsive after error appears
• Moisture sensor light may blink or remain illuminated
Possible Causes
• Moisture sensor contacts are dirty or corroded from lint and detergent residue
• Broken or faulty humidity sensor in the drum
• Loose or disconnected wiring to the moisture sensor
• Malfunctioning sensor control board or electronic module
• Lint buildup blocking the sensor's ability to detect moisture
• Defective thermal sensor causing false readings
• Power supply issue affecting sensor voltage on 240V circuit
Safety Checks You Can Do
• Unplug the dryer from the 240V outlet for 5 minutes, then plug it back in to reset the control board
• Check your home's circuit breaker to ensure the 240V dryer breaker is in the ON position
• Remove and thoroughly clean the lint filter trap with a soft brush to remove all lint and debris
• Inspect the moisture sensor probes (usually located inside the drum) for visible lint or white residue and gently wipe with a dry cloth if accessible from the front
• Vacuum the exterior exhaust vent opening where air exits your dryer duct
• Verify that the dryer exhaust vent duct is not kinked, crushed, or blocked by inspecting the hose behind the unit
• Ensure the dryer is properly vented to the outdoors and not venting into walls or attics, as per USA building codes
• Run the dryer on a test cycle with no clothes to see if the error clears
• Check that all visible wiring connections at the back of the dryer are firmly seated (do not attempt to disassemble)
