All household appliances have a lifespan, and dishwashers are no exception.
How long a dishwasher is expected to last can depend on a variety of factors and may even depend on your specific model, with some machines having a longer or shorter life expectancy than average out of the box.
However, having a vague idea can be useful information to have when it comes to choosing a dishwasher, and budgeting for repairs or replacements.
Average Dishwasher Lifespan
Generally speaking, dishwashers have a good lifespan. Many homes find themselves replacing their dishwashers before they have broken because new models are more efficient or will look better in their new kitchen.
On average, dishwashers will last around 10 years, with most lasting between 8 and 15 years before breaking once and for all.
By using a dishwasher carefully, cleaning properly, and maintaining the appliance as recommended by the manufacturer, you can greatly increase the dishwasher’s chances of reaching that 15-year target.
Extending a Dishwasher’s Lifespan
There are a range of factors that can greatly affect a dishwasher’s expected lifespan. One such factor is the frequency of use.
More use means more wear on components, and the average home runs its dishwasher five times each week.
Machines that are run less frequently will need repairs less frequently and can often last a few more years.
The build quality of the machine will also have an impact on how long it is likely to last.
By opting for a dishwasher from a recognised manufacturer, you not only are likely to purchase a machine that will last longer, but they can be quieter and use less water too.
By cleaning your dishwasher regularly, you can greatly reduce the strain on the appliance, helping it to clean better and last longer than a machine that has been neglected.
If you do need to get the machine repaired during its life, hire experienced and reputable technicians. Whilst opting for a low-cost repair might be tempting, you are often better off spending more and getting high-quality parts.
When Should You Replace a Dishwasher?
It can be difficult to work out when to write off a dishwasher and when to consider replacing it.
No one wants to spend more money than necessary, but there are times when replacing a dishwasher is a better choice than continually repairing it.
If you have got to the point where you are regularly paying for the same repairs just to keep an old dishwasher going, it is probably worth buying a new machine.
Not only will it save on repairs, but new machines tend to save money on water and electricity costs. If it is looking like a repair will cost you just as much as a new dishwasherr, it’s time to throw in the towel.
If the machine is more than eight years old, it is likely approaching the end of its expected lifespan.
Finding replacement parts for older models can be difficult and more expensive, and you might be better off replacing the machine with a newer, more efficient one.
Some small dishwasher repairs are simple and usually worthwhile. These include things like door latches, gaskets, soap dispensers, valves, and switches.
These types of repairs are all small and inexpensive, and usually considerably cheaper than replacing the entire machine.
If the repair is larger and will attract greater labour costs and complicated parts, such as new motors or pumps, it may be more economical to replace the appliance.
When it comes to working out whether a dishwasher repair is worthwhile, compare the cost of the repair to the cost of a new dishwasher.
If the repair is less than half the price of the new dishwasher, the repair is usually a good choice.
If the repair bill goes above half the price of the new machine, seriously consider whether you are better off spending just a little more to get a new one.
