Common Tumble Dryer Faults

I repair a wide range of common tumble dryer problems, from simple faults to more involved electrical, control and heating issues.

Tumble Dryer Fault Possible Causes
Not heating Failed heater element, faulty thermostat, thermal cut-out tripped, blocked airflow, sensor fault, PCB fault
Taking too long to dry Blocked filters, restricted airflow, blocked condenser, overloaded drum, weak heater, moisture sensor fault
Clothes still damp Blocked lint filter, blocked condenser, faulty moisture sensor, incorrect programme, poor ventilation, heater issue
No power Blown fuse, faulty socket, damaged power cable, failed on/off switch, control board fault, door switch fault
Drum not turning Broken drive belt, faulty motor, seized drum, worn jockey wheel, capacitor fault, control board issue
Making loud noises Worn drum rollers, faulty bearings, loose belt, worn jockey pulley, foreign object inside, motor bearing fault
Squeaking or squealing Worn drum bearings, dry or worn rollers, worn belt, faulty tension pulley, motor bearing wear
Banging during cycle Loose drum, worn support rollers, damaged drum seam, foreign object, worn suspension or mounting parts
Stops mid-cycle Overheating, blocked airflow, faulty thermostat, motor overheating, sensor fault, PCB/control fault
Tripping electrics Heater leaking to earth, motor fault, damaged wiring, moisture ingress, faulty mains filter, control board fault
Door not closing Broken door latch, damaged catch, misaligned door, worn hinge, faulty door switch
Water tank warning light Full water container, blocked pump, blocked condenser channel, faulty float switch, blocked internal hose
Condenser light showing Blocked condenser, dirty heat exchanger, restricted airflow, blocked filters, sensor fault
Leaking water Blocked condenser, cracked water tank, blocked pump hose, loose pipe, faulty pump, poor seal around condenser unit
Burning smell Lint build-up, overheating heater, blocked airflow, worn belt, motor issue, electrical fault
Overheating Blocked lint filter, restricted vents, faulty thermostat, failed thermal sensor, blocked condenser, fan issue
Heat pump dryer not drying Blocked filters, dirty heat exchanger, compressor fault, sensor fault, airflow restriction, possible sealed-system issue
Error code showing Heating fault, sensor fault, airflow restriction, door lock fault, motor issue, pump fault, PCB/control fault
