How Long Do Dishwashers Last? Average Lifespan by Brand
Most dishwashers last about 10 years, with the real range running from 7 to 15 years depending on build quality and brand. Budget models average 7–9 years, mid-range units 9–12, and premium brands like Bosch and Miele often reach 12–20 years. Hard water buildup and a neglected filter are the two biggest factors that cut a dishwasher’s life short.
Average Dishwasher Lifespan by Tier
| Dishwasher tier | Average lifespan | Why |
|---|---|---|
| Budget / entry-level | 7–9 years | Plastic components, lighter-duty pumps and motors |
| Mid-range | 9–12 years | Better pumps, stainless tubs, sturdier racks |
| Premium (Bosch, KitchenAid) | 12–15 years | Higher-grade motors, quieter and more durable builds |
| Luxury (Miele) | 15–20 years | Engineered and tested for two decades of use |
The industry average most people quote — roughly 9 to 10 years — is really the mid-point of a wide range. A $400 builder-grade unit hitting 8 years has done its job; a Bosch or Miele at 8 years is barely middle-aged. Build quality, not just age, decides whether a repair is worth it.
Dishwasher Lifespan by Brand
Brand is one of the strongest predictors of how long a dishwasher lasts. These are typical real-world ranges — results vary with water hardness and maintenance:
| Brand | Typical lifespan | Reputation |
|---|---|---|
| Miele | 15–20 years | The longevity leader; tested to 20 years of use |
| Bosch | 12–15 years | Quiet, reliable, strong parts availability |
| KitchenAid | 12–14 years | Durable premium build |
| Whirlpool / Maytag | 10–13 years | Dependable mainstream workhorses |
| GE | 10–13 years | Solid mid-range reliability |
| LG | 10–12 years | Feature-rich; more electronics to fail |
| Samsung | 10–12 years | Good features; more reported control faults |
| Frigidaire | 8–10 years | Budget tier; lifespan tracks price |
What Determines How Long a Dishwasher Lasts
- Hard water — the number-one lifespan killer. Mineral scale builds up on the heating element, spray arms, and pump, forcing everything to work harder. A water softener or regular descaling dramatically extends life.
- Filter maintenance — a clogged filter starves the pump and lets food recirculate. Rinsing the filter monthly is the single easiest way to add years.
- Cycle frequency — a unit run twice a day in a big household wears faster than one run three times a week.
- Overloading & abuse — jamming racks bends spray arms and strains the door and latch over time.
- Incoming water temperature — water that’s too cold makes the heater work harder every cycle.
- Build quality — stainless tubs, better pumps, and metal racks simply outlast plastic ones.
Why Dishwashers Don’t Last as Long as They Used To
Older dishwashers ran on simple mechanical timers and heavy-duty motors that could last 15–20 years. Today’s units trade some of that durability for efficiency, quietness, and features. Modern dishwashers use electronic control boards that can fail, soil sensors and multiple valves that add complexity, and — on budget models — plastic tubs and lighter pumps to hit a price point. They clean better with far less water and energy, but the average lifespan has drifted down toward 10 years. The upside: most modern failures are single-part repairs, not the end of the machine.
Typical Dishwasher Repair Costs
Knowing part costs makes the repair-or-replace call simple. Typical U.S. ranges (parts and labor combined), varying by brand and region:
| Repair | Typical cost |
|---|---|
| Spray arm | $50–150 |
| Door latch / switch | $80–180 |
| Door gasket / seal | $80–200 |
| Water inlet valve | $100–250 |
| Heating element | $120–250 |
| Drain pump | $150–300 |
| Control board | $150–400 |
| Circulation (wash) pump & motor | $200–450 |
Compare a quote to a new dishwasher ($400–$1,500+). On a mid-range or premium unit, most repairs are clearly worth it; on a budget model near the end of its life, a $400 pump job is a closer call.
Signs Your Dishwasher Is Nearing the End
- Dishes come out dirty or gritty even on long cycles, after you’ve cleaned the filter and spray arms
- Standing water in the bottom that won’t drain
- Water leaking onto the floor from the door or underneath
- Rust inside the tub or on the racks, or cracks in the tub itself
- The door won’t latch or seal properly
- It won’t start, stops mid-cycle, or trips the breaker
- Repairs starting to stack up within a year or two
Repair or Replace — the Honest Rule
The benchmark is the 50% rule: if a repair costs more than half of a comparable new unit — and the machine is past half its expected life — replace; otherwise repair. In practice: under 6 years old, repair almost always makes sense. Between 6 and 10 years, it depends on the part — a drain pump, valve, spray arm, or door latch is worth fixing; a failed main pump-and-motor or control board on a budget unit is a closer call. Past 10–12 years on an entry-level model, a major failure usually means replacement. Premium brands like Bosch and Miele are the exception — they’re built to be repaired and run well past 12 years.
How to Make Your Dishwasher Last Longer
- Rinse the filter monthly — the single easiest lifespan extender.
- Run a cleaning cycle monthly with a dishwasher cleaner or vinegar to clear grease and scale.
- Manage hard water — a softener or rinse aid slows mineral buildup on the heater and pump.
- Don’t overload — keep spray arms free to spin and avoid bending racks.
- Wipe the door seal and check spray-arm holes for debris every few weeks.
- Run hot water at the sink before starting so the first fill is hot.

How Dishwashers Compare to Other Appliances
Dishwashers have one of the widest lifespan ranges of any appliance, driven almost entirely by brand tier. Here’s how the majors compare:
| Appliance | Average lifespan |
|---|---|
| Dishwasher | 7–15 years |
| Refrigerator | 10–15 years |
| Washing machine | 10–13 years |

Frequently Asked Questions
How long does the average dishwasher last?
The average dishwasher lasts about 10 years, with a range of 7 to 15. Budget models average 7–9 years, mid-range units 9–12, and premium brands like Bosch and Miele commonly reach 12–20 years.
Which dishwasher brand lasts the longest?
Miele leads, with dishwashers engineered and tested for up to 20 years. Bosch and KitchenAid typically last 12–15 years, while mainstream brands like Whirlpool, Maytag, and GE average 10–13 years.
Is it worth repairing a 10-year-old dishwasher?
It depends on the brand and repair. On a premium unit (Bosch, Miele, KitchenAid), yes — they last well beyond 10 years. On a budget model, a small part like a pump or latch is worth fixing, but a failed motor or control board is a closer call.
How much does it cost to repair a dishwasher?
Most dishwasher repairs run $80–$400 in parts and labor. A spray arm or door latch is $50–$180; a drain pump is $150–$300; a control board is $150–$400; and a circulation pump-and-motor is $200–$450.
Why don’t dishwashers last as long as they used to?
Modern dishwashers use electronic control boards, more sensors and valves, and on budget models plastic tubs and lighter pumps. They clean with far less water and energy, but the added complexity has lowered the average lifespan toward 10 years.
What makes a dishwasher last longer?
Managing hard water with a softener or descaling, rinsing the filter monthly, running a monthly cleaning cycle, not overloading, and running hot water before a cycle.
Do Bosch and Miele dishwashers last longer?
Yes. Premium brands use higher-grade pumps, stainless tubs, and better motors. Bosch typically lasts 12–15 years, and Miele engineers its dishwashers to run up to 20 years with maintenance.
What are the first signs a dishwasher is failing?
Dishes coming out dirty after a full cycle, standing water that won’t drain, leaks onto the floor, rust or cracks in the tub, a door that won’t latch, and repairs stacking up in a short period.
How often should I clean my dishwasher filter?
Rinse the filter at least once a month, and more often if you don’t pre-rinse dishes. A clogged filter is one of the most common causes of poor cleaning and premature pump wear.
