A052578 Genuine Timer FM22 for Ariston Appliances, Ariston Replacement Timer, Ariston Indesit Whirlpool Group Spare Part

A052578 is a genuine Ariston timer, and the manufacturer's description lists it with the reference FM22. Depending on the appliance, a timer may count down a cooking time, switch a function off when time is up, or step a machine through its program. Our records don't confirm which Ariston appliance A052578 belongs to, so compare the number and the FM22 reference with your old timer before ordering.

Common Ariston timer faults

Mechanical timers rely on a small motor or spring and a set of cam operated contacts, while electronic versions rely on a circuit board and relay. Either kind can wear out. Typical faults include a timer that doesn't advance or count down, one that won't switch the appliance off at the end, a buzzer that stays silent, a knob that turns freely without catching, or an appliance that won't start unless the timer is set to manual. Burnt contacts and a stalled timer motor are frequent causes.

Fitting the timer

Isolate the power first, at the circuit breaker for a hard-wired appliance, and use a licensed electrician for that work. Remove the knob and control panel, then label or photograph every wire on the old timer, as timers often have several terminals close together. Transfer the wires one at a time, secure the new timer and test it through a full count or cycle.
