An overview of the dishwasher filter market
According to a Future Market Insights report, the dishwasher parts and accessories market was valued at USD 1870.6 million in 2025 and is expected to grow at a compound annual growth rate (CAGR) of 4.7% to reach USD 2961.1 million by 2035.
This growth in demand is fueled by the increasing demand for kitchen automation, combined with continuous advancements in energy-efficient dishwashers. In addition, the rising investment in smart dishwashers and the growing focus on regulations for sustainable home appliances have led to the industry’s growth.
The longevity of dishwashers has also led to an increase in the dishwasher filter and accessories market, as customers trend towards serviceability instead of disposability, thereby increasing the demand for high-quality replacement components.
What is a dishwasher filter and why is it important?
The dishwasher filter plays a crucial role in keeping dishes clean and extending the dishwasher’s longevity. It is located at the bottom of most dishwashers and traps food particles, grease, and debris during the wash cycle. Without a filter, food particles would re-circulate, leaving residue on the dishes and clogging the system.
There are two types of dishwasher filters:
- Manual-clean filters: They are removable mesh or screen filters that trap food particles and debris. Manual-clean filters should be cleaned at least once a month, especially if one notices an odor, residue, or soap particles on the dishes.
- Self-cleaning filters: They require less frequent cleaning and can be cleaned at least once every three months. Self-cleaning filters grind food particles into small pieces, which then wash down the drain.
As a retailer, you should utilize this knowledge to assist customers in selecting the type that suits their lifestyle and emphasize the importance of regular filter maintenance, particularly for manual-cleaning filters.
Does a dishwasher filter need to be replaced?
The short answer is yes. In many cases, a dishwasher filter will eventually need to be replaced, especially in models that have a manual-cleaning filter. While the filters are designed to last, wear and tear from regular use takes its toll over time.
Signs a dishwasher filter needs to be replaced
Educating your customers about the signs of a worn-out filter is essential. Here are some signs they should look out for.
- Dishes aren’t coming out clean: One of the first signs a dishwasher filter needs replacing is dirty dishes. If their dishes look cloudy and gritty or still have food particles after a full cycle, it is time for a replacement. The filter may be too clogged or worn out and unable to trap debris effectively.
- Foul odors: A musty or sour smell from the dishwasher is an indication that food particles are trapped and rotting in a damaged or saturated filter. If regular dishwasher filter cleaning doesn’t eliminate the smell, replacement is necessary.
- Visible damage: If the mesh or plastic in the filter is cracked, frayed, or feels brittle, it’s time to replace it. A damaged filter mesh will allow food debris to pass through, potentially damaging other dishwasher components.
- Drainage problems: A clogged or faulty dishwasher filter will interfere with the appliance drainage. If customers notice water pooling at the bottom of the dishwasher, it might be due to a clogged or damaged filter.
- Unusual noises: A broken or loose filter may rattle, vibrate, or even produce grinding noises in the dishwasher. The sounds indicate the filter is interfering with other dishwasher components.
Dishwasher filter replacements are required at least every two to three years, depending on the usage and maintenance. Self-cleaning filters rarely require replacements. However, people who use hard water may need to replace their filters more often as the hard water shortens the filter’s lifespan.
How to clean a dishwasher filter
Regular dishwasher filter cleaning prevents clogs and extends the appliance’s lifespan. You can add value by educating your customers on how to clean their dishwater filters. Here is a simple step-by-step guide to provide to your customers.
Step 1: Locate and remove the dishwasher filter
To locate the dishwasher filter, remove the bottom dish rack to see the bottom of the dishwasher. The filter is at the back corner or the base of the bottom spray arm. Most dishwasher filters have two parts. Turn the upper part and take it out to reveal the lower part. Lift it gently and pull the lower part out.
Step 2: Clean the filter
To clean the filter, run clean, warm water through it to remove debris. For the more challenging particles, soak the filter in warm water for a few minutes and use a soft brush or sponge to scrub away the debris. Avoid using a wire brush or wire sponge, as this may damage the filter mesh.
Step 3: Reinstall the filter
Once the filter is clean, return the lower part of the filter and secure it in place. Fit the upper part into the opening of the lower part and turn it clockwise to secure it in place. Ensure the filter is securely in place, as a loose one can damage your dishwasher.
If one has gone a long time without cleaning the dishwasher filter, they can deep clean it by soaking it in vinegar after rinsing it with warm water. Have a solution of equal parts water and vinegar, and soak the filter for at least 30 minutes. Clean it as above.
Summing up
A dishwasher filter may be a small component, but it plays an imperative role in the appliance’s performance.
For small businesses and retailers, understanding dishwasher filter maintenance is a win-win. You educate customers on cleaning and replacing filters, which boosts appliance performance and also increases sales of replacement parts and accessories.
By positioning yourself as a trusted source of information, you build customer loyalty and drive repeat sales.
