Shop DishwashersAverage Lifespan of Dishwashers
According to reputed appliance repair technicians and manufacturers, the average home dishwasher lasts between 10 to 15 years with regular use and proper maintenance. Even an appliance from the best dishwasher brands will only last 15 to 20 years at most.
However, this number is just an approximation as the actual lifespan varies based on several aspects. High-quality brands from reputed companies often outlive the average, while lower-cost or lesser-known models may conk out earlier.
The average also assumes regular use of 120 to 160 dishwasher load cycles per year. Dishwashers used less frequently are likely to last longer since components don't see as much wear and tear.
On the other hand, units subjected to overuse in large households may show signs of aging sooner.
Overall, with good care practices, and in average home settings, the appliance can serve a dishwasher life expectancy of 10-15 years.
Factors Affecting Lifespan
Several factors influence the life of a dishwasher before needing significant repairs or replacement. Even the highest rated dishwashers break down over time depending on the following influences:
- Water Quality: Hard water with higher mineral content can clog pipes, valves, and pumps over time, reducing effectiveness and increasing the risk of leaks. Proper water filtration helps.
- Maintenance Habits: Regular cleaning of filters and interior, unclogging drain pipes, and addressing small issues promptly to extend lifespan.
- Usage Patterns: Overloading, improper loading, frequent partial loads, and very large households adding to cycle counts can accelerate wear.
- Manufacturing Quality: More durable components and rigorous quality control result in longer-lasting higher-end brands compared to cheaper models.
- Repair History: Major repairs involving component replacements decrease the remaining functional lifespan. Regular servicing maximizes longevity.
- Age of Installation: Older homes may have unsuitable plumbing and electrical work impacting performance.
- Environmental Factors: Extreme climate zones and natural disasters like flooding pose additional stress. Proper protection helps.
Signs Your Dishwasher Needs Replacing
All appliances have a limited lifespan before components start to wear out. While the expected life of dishwashers is 10-15 years with proper maintenance, over time performance will decline as parts deteriorate. Here are some signs that indicate it may be time to purchase a new dishwasher:
The most obvious sign is a decrease in cleaning performance. Dishes may emerge from the cycle still coated in leftover food residues, even after running the dishwasher multiple times. Issues like a failing rinse aid dispenser can result in spotty drying results.
Physical damage from extended use also shows it's near the end. Watch out for telltale signs like rust marks on the interior tub, cracks in materials, or broken racks. Water leaks from different areas are a warning the unit needs replacing.
Excessive noise also suggests internal problems. Loud banging or grinding during cycles means components are struggling.
Check efficiency as well. Older models use more water and energy per load. New ENERGY STAR dishwashers are vastly more efficient to run.
Frequent repair calls that fail to fully resolve issues are a clear sign it's time for a replacement. Multiple repairs can reduce the appliance's lifespan. If repair costs approach half the price of a new unit, consider upgrading.
Maximizing Dishwasher Lifespan
Taking proper care of your appliance is vital to extend the expected average life of your dishwasher and to reduce expensive repairs down the road. Performing regular maintenance is key. Be sure to thoroughly clean the door gaskets and interior monthly. Also, scrub the inner filters under warm water weekly to remove trapped food particles.
It's essential to properly load the dishwasher. Arrange dishes spaced out without stacking so water can reach all surfaces. Overcrowding strains moving components and leaves patches of dirt.
Use the appropriate type and amount of detergent suited for each load. Dissolve pods or tablets fully in the dispenser compartment before running the cycle for optimum cleaning.
Inspect water supply lines periodically as well. Kinks or cracks can cause costly floods if not addressed promptly. Hard water deposits also decrease performance - consider installing a water softener in severe cases.
Schedule professional maintenance checkups every couple of years too. A technician can replace worn filters and gaskets during these visits to maximize the unit's usable lifetime.
Choosing eco-friendly cycles tailored for partial or delicate loads also helps reduce utility bills in the long run. With proper care habits, a dishwasher can last over a decade of service.
When to Consider a New Dishwasher
No matter how diligently a homeowner maintains their appliance, wear from continual use will diminish a dishwasher's cleaning effectiveness over time.
Key components like the heating elements, motors, and control electronics all degrade gradually, leading to the need for replacement. If repair costs begin exceeding 50% of the estimated cost of a new replacement unit, it's usually better to upgrade to one of the new most recommended dishwashers.
Multiple repairs signify components are reaching their service limits. Further fixes only further diminish the return on investment you are getting. So, unless repairs are covered by a warranty, relatively affordable or straightforward, you should consider replacing the appliance over repairing it.
Exceeding the average 10-to-12-year lifespan is also a warning sign even with exemplary maintenance. Most parts experience wear after a decade of cycles that result in frequent problems down the road no matter the TLC provided.
Moving to a new home often prompts a replacement as well. Modern appliances offer better efficiency than older appliances do not. So, getting a new one after a move might not be a bad idea.
You should also think about throwing out your old appliance and replacing it with a new one when the features seem dated. High-end new models offer convenient features like Wi-Fi connectivity and smart features, which make washing dishes easier.
For dishwashers over 15 years old that have run into some problems, repairs above the $300 mark often surpass the unit's current value. As a result, you can save money by replacing a dated model, since the cost of repairing it greatly exceeds the actual value of the appliance.

FAQ
Here are some frequently asked questions about dishwashers.
How often should you replace a dishwasher?
Most dishwashers last 10-15 years with proper use and maintenance. Consider replacement if repair costs are near replacement value or the unit is over 12 years old.
What is the most common failure of a dishwasher?
Failures of circulating pumps, wash motors, and heating elements are among the most frequent, eventually hindering the machine's ability to fully clean dishes. Regular maintenance mitigates such problems.
