As Lindsay Jones, Maytag’s (opens in new tab) New Product Brand Manager tells us: “Dishwashers can significantly cut down on clean-up time, especially when compared to having to wash everything by hand.

We’ve rounded up a number of reasons why your appliance might not be performing at its best. Plus some top tips on how to prolong your dishwasher’s lifespan.

Dishwasher not cleaning properly? Try these tips
- You’re overloading your machine One of the main reasons why your dishwasher isn’t cleaning properly? It’s up to – or over – its capacity. Many of the dishwashers come with three racks, with one for your plates and larger items of your kitchenware, one for your glasses and a third for all your cutlery. A good rule of thumb to keep in mind is that a dishwasher with a 14-place setting should be able to handle 14 plates, cutlery and glasses only. Double check your dishwasher’s manual to find out the number of place settings and make sure you only load your dishwasher up to this capacity.
- The filter is clogged Your dishwasher’s filter keeps uneaten pieces of food and leftover residue from circulating throughout the machine. An indication that your filter is clogged, is a drop in your dishwasher’s cleaning performance. You might also be able to see and smell grime on your dishes. Lindsay says, “Depending on how frequently you’re using your dishwasher, you should clean your filter anywhere from once a year to once a week. “Removing, cleaning and reinstalling your dishwasher filter is easy and takes only a few minutes. How often you should clean your filter depends on the number of loads you run per week and whether you rinse or scrape your dishes before loading.” Learning how to clean a dishwasher filter (opens in new tab) will keep your machine in good condition.
- Your soap dispenser is clogged When the detergent dispenser is clogged, it will stop your dirty dishes from being cleaned with soap. This can happen when you’re using too much detergent or if remnants of a tablet have dried and become lodged. So how do you fix this problem? “When it comes to your dishwasher, less is more,” Lindsay tells us. “Start with one tablespoon of detergent or one detergent tablet or pack. If your dishes still come out dirty, try increasing the amount of detergent (if using liquid or powder) or switch up the brand.”
- The arm spray is clogged Like any other aspect of your dishwasher, your arm spray is essential to the performance of your dishwasher’s cleaning power. Just as its name suggests, it’s the feature of the dishwasher that sprays out water onto your used dishes. However, as Lindsay explains, “Over time, minerals can build-up in your water and cause issues for your dishwasher. “Maytag recommends using ‘soft water’ or using a descaler if you have ‘hard water’. If this build-up occurs, descaling agents such as affresh cleaning tablets power away limescale and mineral build-up from your dishwasher.”
- The water temperature is low The best temperature for your dishwasher to rid dirt and grime from your plates is a temperature between 120F to 150F. If you notice your cleaning tablet isn’t dissolving, it may be because the water temperature isn’t hot enough to dissolve it. Lindsay adds: “It’s important to make sure the hot water supply to your dishwasher runs “hot” (120℉ target temp). If the water delivered to the dishwasher is cold, the unit will run longer to reach and maintain the optimal temperature.”
How to prolong your dishwasher’s lifespan
Generally speaking, many of dishwashers have a lifespan of between five to 10 years. To help you get the most out of your dishwasher, Lindsay has shared some tips.
- Show your dishwasher some love “Your dishwasher is a labor-saving friend in your home, but once a month or so, it needs some love,” Lindsay says. “Over time, soap scum, undissolved detergent, food debris and grease can build up in your dishwasher, especially in its trap and drain, but also on the walls, seals, arms and basin. This residue and grime can create a breeding ground for germs and can also get cycled back around your dishes when you run your machine.” Lindsay suggests using a monthly dishwasher cleaner for the best results. She adds, “Set a reminder to make it part of your once-a-month cleaning routine.”
- Always use rinse aid Rinse aid is your dishwasher’s friend. That’s because it helps to prevent water spots from forming on your kitchenware and glasses. It also helps the dishes dry faster.

- Load your dishwasher correctly Lindsay says, “Load dishes so they’re slanted and not touching and avoid nesting. Check the detergent packaging to make sure you’re using the right amount. Dirty surfaces should face the center. Put plastic in the top rack, farther away from the heat source. Make sure spray arms aren’t blocked by tall items below and are able to spin freely. Also check that nothing will block the detergent dispenser.” Lindsay also recommends unloading the bottom rack first and leaving plastic items for last, so any leftover water won’t drip on your dry bottom rack dishes.
