How long does a dishwasher last? Most last roughly 9 to 13 years, with budget models often at the short end and well-kept machines at the long end. Hard water, heavy use and skipped cleaning shorten that. When a machine is past about 10 years and needs a major repair, replacing it usually makes more sense.
How long does a dishwasher last: typical lifespan
Dishwashers are mechanical and electrical, with pumps, seals, valves, racks and electronics. The numbers below are general ranges, and your manual or warranty may say more for your model.
| Quick facts: how long does a dishwasher last | |
|---|---|
| Typical life | About 9 to 13 years |
| Shortens it | Hard water, daily heavy loads, no filter cleaning, rough use |
| Extends it | Regular cleaning, soft water, gentle loading, prompt repairs |
| Replace when | Old machine plus a major repair, or repeated failures |
What shortens the life
| Cause | Effect |
|---|---|
| Hard water scale | Clogs spray arms, coats heaters, wears seals |
| Skipped filter cleaning | Strains the pump and leaves dishes dirty |
| Overloading | Blocks spray and stresses motors and racks |
| Leaks and damp | Corrode wiring and the floor around it |
| Cheap, light-duty models | Fewer metal parts and thinner pumps |
Signs it is nearing the end
- Dishes come out dirty even with a clean filter and arms.
- Rust or cracks inside the tub or on the racks.
- Water leaks that return after repairs.
- Cycles are loud, grinding or run far longer than before.
- The heater, pump or control board fails more than once.
Repair or replace
| Situation | Usual choice |
|---|---|
| Under about 7 years, single simple fault | Repair |
| About 8 to 10 years, minor part such as a gasket or hose | Repair |
| Over about 10 years, pump, motor or control board failure | Replace |
| Repair costs more than about half the price of a comparable new unit | Replace |
| Multiple faults in a short time | Replace |
How to get more years
- Clean the filter monthly and the spray arms every few months.
- Wipe the door seal and run a cleaning cycle regularly.
- Use the right amount of detergent and rinse aid.
- Scrape rather than pre-rinse, but remove bones and glass.
- Fix small leaks and noises early, before they damage the pump or floor.
- Deal with hard water using a softener or a descaler.
What makers and warranties tell you
Maker warranties are usually one to two years on parts and labor, with longer cover on the tub or racks on some models. A warranty is not a lifespan, but it shows what the maker expects to stand behind. Real-world life depends far more on water quality, load size and care than on the printed number.
A simple way to decide
Write down the age, the repair quote and the price of a comparable new machine. If the machine is past 10 years and the repair is more than about half the price of a new one, replacing is usually the sound choice. If it is under 8 years and the fault is simple, repair. When people ask how long does a dishwasher last, this checklist is more useful than any single number.
Planning ahead
Set aside a little each year toward a replacement once the machine passes the 8-year mark. Take photos of the model and serial number, because they speed up parts and warranty checks.
What to consider when replacing
New machines run quieter and use less water, but they can take longer per cycle. Measure the space, check the water and drain connections and compare warranties. Efficiency features matter less than a good pump and filter design.
Safety
If you see water leaking onto the floor, turn off the water supply and unplug the machine or switch off its breaker. Never reach into the tub while the cycle is running. Knowing how long a dishwasher lasts helps you plan a replacement before a leak damages the kitchen floor.
How long does a dishwasher last: a practical view
Most dishwashers last several years, and many keep working well for a decade with steady care. How long does a dishwasher last depends on the water hardness, how often it runs, and whether the filter and spray arms are cleaned. Hard water and heavy use wear out the pump and the seals sooner. A machine that is cleaned monthly and loaded correctly tends to outlast one that is neglected. Keep the warranty and the purchase date with the owner's manual, so you know whether a repair is still covered. Reviewing the repair history helps too: several small faults in a short time often signal that the machine is nearing the end of its life.
Many owners ask how long does a dishwasher last after a major repair, and the answer depends on the part replaced. Knowing how long does a dishwasher last for your model helps you decide when a repair stops making sense.
A dishwasher that is repaired early usually costs less than one that breaks down repeatedly, so track how long does a dishwasher last in your own home.

Frequently asked questions
How long does a dishwasher last?
Most last about 9 to 13 years. Hard water, heavy use and skipped cleaning shorten that, while regular maintenance, soft water and gentle loading help the machine reach the upper end of the range.
How many years should a dishwasher last?
Around 10 years is a common expectation. Well-built models can run longer and basic ones sometimes fail sooner. Your manual or warranty may give a figure for your model, and use and water quality change it.
Is it worth repairing a 10 year old dishwasher?
Usually only for a small, cheap part such as a gasket or hose. For a failed pump, motor or control board on a machine that old, replacement is typically better value, especially if repair costs near half a new one.
What are signs my dishwasher is dying?
Dirty dishes despite cleaning, rust, leaks that return, loud grinding, cycles that never finish and repeated part failures are common signs. One fault is a repair; several in a short time is a warning.
Does hard water shorten dishwasher life?
Yes. Scale builds up on spray arms, heating elements and seals, reducing performance and wearing parts. A water softener, a descaler cycle and rinse aid reduce the damage. Softening the water also helps rinse aid and detergent work better.
How can I make my dishwasher last longer?
Clean the filter monthly, wipe the seal, run a cleaning cycle, avoid overloading, use the right detergent and fix small leaks or noises early. Dealing with hard water also makes a real difference.
Do expensive dishwashers last longer?
Often, but not always. Higher-end models tend to have sturdier pumps, steel tubs and better filtration, yet careful use and maintenance matter as much as the brand or the price.
Should I repair or replace a dishwasher that leaks?
It depends on the cause and age. A worn door seal or loose hose is a simple repair. A leak from a cracked tub or a failed pump on an old machine usually means replacement. Shut off the water first.
How long does a built-in dishwasher last compared with a portable one?
Built-in models generally last longer than portables, which have lighter-duty parts and more wear from being moved. Both vary a lot with maintenance and water quality. Regular filter cleaning helps both types last.
When should I call a pro about my dishwasher?
Call if it leaks, will not drain or start, makes grinding noises or shows repeated error codes. A technician can tell you whether a repair makes sense for the machine age.
