Appliance repairers diagnose and repair faults in domestic electrical appliances, helping households restore equipment that is not working properly, is damaged or is operating inefficiently. Common items include washing machines, tumble dryers, dishwashers, fridges, freezers, cookers, ovens, hobs and microwaves. Some businesses also work on smaller appliances such as vacuum cleaners, kettles and coffee machines, while others specialise in particular brands or types of equipment. A repair visit may involve inspecting the appliance, identifying the cause of a fault and explaining whether repair is practical. Work can include replacing components such as pumps, motors, thermostats, seals, heating elements, door locks or control boards, as well as clearing blockages and addressing leaks or unusual noise. Repairers may provide call-out or workshop services, source suitable replacement parts and test an appliance after work is completed.
