Appliance Lifespan Guide – Know How Long Your Appliances Should Last

Dishwasher: 9‑12 years. Pump and spray arm wear quickly. A foul smell, poor cleaning, or water at the bottom usually means the appliance is aging.

Microwave: 7‑10 years. The magnetron is the most costly part. If it sparks, hums without heating, or stops turning, replace it.

Boiler/Water heater: 10‑15 years for boilers, 8‑12 years for electric water heaters. Corrosion, rust, or a loss of pressure are clear signs it’s nearing retirement.

Simple Steps to Extend Appliance Life

Regular cleaning is the cheapest way to add years. Remove lint from dryer vents, clean fridge coils, and clear dishwasher filters. These tasks keep engines from overheating and parts from clogging.

Don’t overload. A washing machine packed to the brim or a dryer slammed with too many heavy items strains motors and bearings. Follow the manufacturer’s load limits – it saves energy and reduces wear.

Watch for early warning signs. A fridge that runs constantly, a dishwasher that leaks a few drops, or an oven that takes longer to preheat all indicate parts are getting tired. Early repair often costs less than waiting for a full failure.

Schedule annual check‑ups for big gear like boilers, heat pumps, and washing machines. A professional can tighten loose connections, replace worn seals, and catch corrosion before it spreads.

Finally, consider the cost of repair versus replacement. If a part costs more than half the price of a new unit, or the appliance is already past its average lifespan, buying a new, energy‑efficient model usually pays off in the long run.

Knowing the typical lifespan of your home appliances helps you stay ahead of breakdowns, save money, and keep your household running smoothly. Use these averages as a guide, keep up with basic maintenance, and you’ll get the most out of every machine.
