5 Dishwasher Mistakes to Avoid, According to an Expert
I used to think using a dishwasher was as simple as loading the dishes, adding detergent, and pressing Start. But a few common habits can actually make dishes come out less clean and may put unnecessary strain on the appliance.
The good news is that most dishwasher mistakes are easy to fix. From over-rinsing plates to loading them incorrectly, small changes can make a noticeable difference.
Why These Mistakes Matter
A dishwasher needs the right combination of water pressure, detergent, heat, and proper loading to clean effectively. If dishes block the spray arms or detergent is released at the wrong time, even a powerful dishwasher may struggle to deliver good results.
Avoiding these five mistakes can help improve cleaning performance and make everyday dishwasher use more efficient.
1. Rinsing Dishes Too Much Before Loading
One of the most common habits is rinsing dishes until they’re almost completely clean before putting them in the dishwasher.
For most modern dishwashers, this isn’t necessary.
Instead, scrape large pieces of food into the trash or compost and load the dishes directly. Excessive pre-rinsing wastes water and can make it harder for some dishwasher detergents to work as intended.
Better approach: Remove large food scraps, but leave normal food residue for the dishwasher to handle.
2. Using Dishwasher Detergent Incorrectly
Where and how you add detergent can affect the washing result.
The detergent dispenser is designed to release detergent during the appropriate part of the cycle. Simply dropping a tablet into the bottom of the dishwasher may cause it to dissolve too early on some cycles.
For the best results, place the detergent in the designated dispenser and follow the instructions in your dishwasher’s manual.
If you’re using powder or liquid detergent, use the amount recommended by the manufacturer rather than assuming that more detergent means cleaner dishes.
3. Forgetting Routine Dishwasher Maintenance
Even if you use your dishwasher correctly, it still needs occasional maintenance.
Food particles and mineral deposits can accumulate in different parts of the machine, affecting performance and causing unpleasant odors.
Regularly check and clean:
- The dishwasher filter
- Spray-arm openings
- The door seal
- The detergent dispenser
- The interior for mineral or food buildup
If your dishwasher uses rinse aid or dishwasher salt, refill these according to the manufacturer’s instructions.
A clean filter and unobstructed spray arms allow water to circulate properly and can help your dishwasher clean more effectively.
4. Loading Dishes the Wrong Way
