How to boost a dishwasher's life expectancy

Want to go about expanding the lifespan of a dishwasher? We've got you covered. If you want to get the most out of your dishwasher, there are plenty of approaches you should take. Using the following tips may help you slightly prolong your dishwasher's life.

1. Only run it when it's full

Are you guilty of putting the dishwasher on when it's not full? If the answer is yes, you are wasting energy and lowering your dishwasher's life expectancy. As with any home appliance, the more you use it, the less time it will last. That is the case with most of the general appliances that you have in your kitchen. If you want to prolong the life of your dishwasher, wait until it is full before you decide to switch it on for a cycle.

2. Scrape your plates before putting them in

Once you have finished your dinner, always remember to scrape your plates afterwards. You don't want tiny bits of food and gunk to clog up your dishwasher. When you put things into the dishwasher that have bits on them, it triggers the soil detector. That means your dishwasher must work extra hard (and use more water) to clean your plates. As well as scraping your plates, it's a good idea to be clued up on the things you should never put in the dishwasher

3. Clean your dishwasher regularly

Do you know how to clean a dishwasher? Be honest, when was the last time you did it? The truth is that most people don't bother to clean this home appliance. However, if you want to prolong the life expectancy of your dishwasher, the easiest way to do it is to clean it. Make sure you invest in some quality dishwasher salt. This product helps to soften the water and also cleans the internal workings of the dishwasher. These two benefits may prolong its life expectancy.

4. Load your dishwasher well

If you fail to load your dishwasher correctly, you may find that plates and cups fall over during the cycle. That can damage areas of your dishwasher and lead to a shorter life expectancy. To overcome this simple problem, it takes a simple solution. All you need to do is read the user manual. Each of the guides that come with dishwashers tends to have instructions on how to load them the right way. Don't skip over this all-important step.

When is it time to buy a new dishwasher?

No matter how well you look after your home appliance, there will be a time when you need a dishwasher replacement. Here are some of the telltale signs:

The dishwasher is 10+ years old

When your dishwasher is over 10 years old, you will notice that it doesn't clean as well as it once did. Moreover, older home appliances are less energy efficient than new products. When your dishwasher reaches this ripe-old age, you may want to consider a dishwasher replacement.

It's been repaired (more than once!)

When there is a problem with your appliance, you can get a dishwasher repair. However, you might want to cut your losses if you call out a handyperson every month or two. At that point, buying a new dishwasher may be more cost-effective.

It's not cleaning your stuff

Of course, the only reason to get a new dishwasher is if it is no longer cleaning your things well. When this happens, it's wise to get a dishwasher replacement. Make sure you research and read a load of reviews before choosing the right one. If you've noticed your dishwasher isn't drying anymore, take a look at our other guide.
