Not heating
A failed heater element or thermal cut-out, a thermostat or sensor or, on heat-pump dryers, a blocked filter or heat exchanger.
Before we arrive: Clean the fluff filter and empty the water tank, then note whether it’s cold from the start or cools mid-cycle.
Drum not turning
A snapped belt, worn rollers or pulley, the motor or a door switch.
Before we arrive: Listen for whether it hums when you press start, and tell us.
Taking too long
A blocked filter, condenser or vent hose, or a heater, thermostat or damp sensor fault. Heat-pump dryers also run longer by design.
Before we arrive: Clean the fluff filter and empty the water tank, then try one more load.
Another fault
Squealing or knocking, error codes, a door that won’t latch or a burning smell.
Before we arrive: Stop using it if you smell burning, and note any error code on the display.
