Should You Replace Your Washer and Dryer at the Same Time?

A washing machine and a dryer live side by side and get used in the same breath, so when one gives out it feels natural to wonder whether its partner should go too. You do have a real choice here - and the right call leans less on the appliances themselves than on their age, your budget, and how well the two are sized to each other.
The short answer
No, you do not have to. The washer and dryer are separate machines, so you can replace only the one that failed and keep the other. People often buy the pair together anyway - a matched set stacks and fits neatly, bundles usually add a discount plus one delivery and haul-away, and if one unit died around year 12 the other is likely close behind. But if the surviving machine is much newer or working fine, replacing it too just wastes money. Whichever route you take, buy efficient and keep your per-kWh rate low, because that rate multiplies every load for the life of the machine.
They Are Two Independent Machines
Despite sharing a cabinet color and a corner of the house, a washer and a dryer have almost nothing in common mechanically. One fills with water, tumbles, and spins; the other blows heated air. They share no parts and no failure points, so the death of one tells you nothing certain about the other. That means replacing a single unit is completely normal - a broken washer does not obligate you to touch a dryer that still runs. Most laundry machines last roughly 10 to 14 years, and you can read how that breaks down in our guide on how long a washer and dryer last.
Good Reasons to Replace Both at Once
There are sensible reasons people still swap the pair together. A matched set simply looks and fits better - the two line up, stack cleanly in a closet, and share a control style. Buying them as a bundle usually earns a discount over two separate purchases, and you pay a single delivery fee while both old units get hauled away in one trip. There is also an age argument: if the machine that failed was around 12 years old, its partner is statistically close to the same fate, so replacing both now can spare you a second delivery charge and an inconvenient breakdown a few months later. And there is a quieter, practical one - capacity. If you upgrade to a large high-capacity washer but keep a small older dryer, a full wash load will not dry in a single cycle, so you end up running the dryer twice. That doubles the energy of the most power-hungry half of laundry on every load.
The math on a capacity mismatch
An electric dryer is the expensive half of laundry, pulling roughly 3 kWh a cycle. If a mismatched, undersized dryer forces two cycles to finish one big wash load, you are spending about 6 kWh where 3 would do - roughly 40¢ extra per load at a Texas rate near 14¢/kWh. Do that for five loads a week and it is about $8 a month, or close to $100 a year, quietly wasted on a size mismatch. Matching capacity - even across two different brands - avoids it.
Good Reasons to Replace Only One
The case for keeping a machine is just as valid. If the surviving unit is much newer - say you already replaced the dryer two years ago - throwing it out to complete a set is money down the drain. A working appliance has value, and a mismatched-but-functional pair costs you nothing in performance as long as their capacities are compatible. If money is tight, replacing only the failed machine now and buying its partner later, ideally on a sale weekend, spreads the cost out. Our guide on the best month to buy a washer and dryer covers when those markdowns tend to land.
If You Are Replacing, Buy Efficient and Durable
Whenever you do buy new - one machine or two - two features decide what the purchase really costs you over the next decade. The first is efficiency: an ENERGY STAR washer uses less water and spins clothes drier so the dryer has to work less, and an ENERGY STAR dryer with a moisture sensor stops when the load is actually dry instead of running on a fixed timer. The second is durability, because a machine that lasts spreads its price and its haul-away hassle over more years; our guide on the longest-lasting washer and dryer brands is worth a look before you commit. Efficient and long-lived is the combination that keeps laundry cheap - but only if the third piece is in place.
Your Per-kWh Rate Follows the Pair for a Decade
That third piece is your electricity rate. Efficiency sets how many kilowatt-hours each load uses; your effective rate sets what every one of those kilowatt-hours costs. A new pair might run 12 to 15 years, and across that whole span the rate is the multiplier on every wash and dry you will ever do. A home paying about 18¢ per kWh spends nearly 30% more on the identical laundry than a home paying about 14¢ - no efficiency upgrade closes that gap, only a better plan does. The catch is that the cheapest plan depends on how much your household actually uses, not the advertised 1,000 kWh headline, so it pays to compare at your real usage.

A new washer and dryer is a decade-long commitment - make sure the rate multiplying every load is as low as it can be. Compare every plan in your ZIP at your real usage in under a minute.

Should you replace a washer and dryer at the same time?
You do not have to. A washer and a dryer are separate machines with their own motors and controls, so you can replace only the one that failed and keep the other running. Many people buy the pair together anyway because a matched set fits and stacks neatly, bundles usually come with a discount plus a single delivery and haul-away, and if one unit died around year 12 the other is statistically close behind. But if the surviving machine is much newer or working fine, replacing it too just wastes a good appliance.
Do a washer and dryer need to match?
No, they do not need to match to work - any dryer will dry the clothes any washer has cleaned. Matching mostly buys you looks and fit: a set from one brand stacks cleanly and lines up in the space. What matters functionally is capacity. If you pair a large new high-capacity washer with a small older dryer, a single full wash load will not fit in one drying cycle, so you run the dryer twice and waste energy. Match the capacity even if you do not match the badge.
Is it cheaper to buy a washer and dryer together?
Often, yes. Retailers regularly discount a washer-and-dryer bundle below the price of the two bought separately, and you pay one delivery fee and get both old units hauled away in a single trip. Buying during a holiday sale weekend stacks a seasonal markdown on top. The savings are real but one-time, though - the bigger long-run cost is the electricity each machine uses for the next decade or more, which your per-kWh rate quietly sets.
If my washer dies, should I replace the dryer too?
Only if the dryer is also near the end of its life or noticeably undersized for a new washer. If your washer failed around the 10-to-14-year mark, the dryer is probably close behind, so replacing both can save a second delivery fee and future downtime. But if the dryer is much newer or working perfectly, keep it - scrapping a good machine just to make a matched set rarely pays off. Either way, if you buy new, choose an efficient ENERGY STAR model so the running cost stays low.
