Your dishwasher is essential in your home as it helps save you time and money and keeps your dishes sparkling clean. However, over time, it will start to lose its efficiency and performance due to wear and tear. When this starts, you will have to decide when it’s time to purchase a new dishwasher.

This guide aims to help you make a more informed decision. We’ll discuss the main signs that it’s time to purchase a new dishwasher and give you some useful tips for deciding on the perfect replacement.

Let’s get started.

Signs it’s time to replace your dishwasher

When deciding to replace your dishwasher, there are many signs you should look out for. If any of the following signs apply to your dishwasher, we recommend you purchase a replacement:

Dishwasher is getting old

Typically, dishwashers have a lifespan ranging from seven to twelve years. If your dishwasher falls within this age range and starts showing signs of malfunction, you may want to consider purchasing a new one. If you’re unsure of the exact year your dishwasher was manufactured, consult the user manual or search for the model number online.

Dishwasher isn’t cleaning effectively

One indication of declining dishwasher performance is when your dishes consistently come out dirty, even if you regularly clean your dishwasher. If you notice this issue persisting, your dishwasher’s cleaning abilities may have diminished, and it’s time for an upgrade. 

Dishwasher is damaged

If you start noticing damage to your dishwasher, such as rust, broken door seals, and faulty spray arms that are significantly impacting its performance and efficiency, those are signs that your current dishwasher won’t last much longer. Investing in a new dishwasher will be more practical if these problems occur frequently and the repairs become expensive.

Dishwasher is noisy

Unusual and loud noises from your dishwasher during wash cycles might signify faulty internal components. When your dishwasher makes loud noises, getting a technician to inspect your appliance is a good idea. Depending on the cost of replacing these parts, opting for a new dishwasher could be a more cost-effective choice. 

Higher energy bills

An older, inefficient dishwasher can consume more energy, increasing utility bills. To reduce energy costs and promote environmental sustainability, upgrading to a more energy-efficient model is wise. Thankfully, most new dishwasher models are very energy-efficient, so even if your budget isn’t high, your new dishwasher will likely be much more efficient than your current model.

How to choose a new dishwasher

When you’re in the market for a new dishwasher, several essential considerations can guide you in making the right choice. You should select a dishwasher that fits your kitchen space, aligns with your budget, and meets your needs. 

A well-chosen dishwasher can make a noticeable difference in your daily life, saving you time, effort, and money while ensuring clean and sparkling dishes after every wash. Here are the primary considerations to take into account:

Dishwasher size

Start by measuring the space where you plan to install the dishwasher. Ensuring the dishwasher fits perfectly in the designated area is crucial. You should also consider the internal capacity of the dishwasher based on your family’s dishwashing needs. A larger dishwasher will benefit larger families or those who frequently entertain guests.

Your budget

Determine a budget for your dishwasher purchase. It’s essential to strike a balance between affordability and quality. While higher-quality models often offer better longevity and performance, there are also budget-friendly options available that can serve your needs adequately. Once you know your budget, create a shortlist of dishwashers that fit within it.

Energy efficiency rating

It’s a good idea to look for dishwashers with high energy efficiency ratings. These models will help reduce your household’s energy consumption, ultimately saving you money on household costs. Not only will you save on utility bills, but you’ll also be doing your bit for the environment.

Noise level

Consider the noise level of the dishwasher, especially if you live in a smaller space or have an open-plan layout. Checking the dishwasher’s decibel rating will give you an idea of how quiet or noisy it will be.


Explore the various features available in modern dishwashers. Look for features such as multiple drying options, delayed start timers, and smart capabilities. These additions can significantly enhance the convenience and efficiency of the dishwasher, making your dishwashing experience even more seamless.

The bottom line

Knowing when to replace your dishwasher will help ensure you and your family have a functional dishwasher at all times. Look for signs of wear and tear, and consider upgrading if your dishwasher is old, malfunctioning, or costing you more to run. When choosing a new dishwasher, consider the size, capacity, energy efficiency, noise level, and other features that best suit your needs and budget.
