Wolf appliances are specifically designed to last far longer than most other appliances. In general, you can expect yours to last around 20 years, though there is some variance for different appliances and use cases.
Typically, the lighter use the appliance receives, the longer it will last. So, if you use your oven multiple times per day, it won’t last quite as long as one that is used two or three times a week.
Environmental factors can also make a difference in the lifespan of appliances. If you live in a particularly humid area or don’t do much to control the temperature in your home, that can reduce the lifespan of any appliance.
