A dishwasher is a kitchen appliance that is connected to the hot water supply in your home, and uses rotating water spraying arms to wash away food and grease from your dishes, pots, pans, and silverware.
A dishwasher will typically have a water heater as part of it that will raise the temperature of the inlet hot water supply even higher, so that it helps the unit clean more effectively. And some models will have multiple settings, which can allow you to save energy by allowing the dishes to air dry, rather than using a heating element in the appliance. Any obstruction of the water’s flow greatly reduces the dishwasher’s washing efficiency.
Routine Care Task
Treat for scale build-up
Removing the deposits from your dishwasher’s heating element improves the efficiency of the heating element and improves the appearance of the inside tub.
Timing: Every 2 months: February, April, June, August, October, December (yearly)
Perform annual maintenance
Annual maintenance improves the operating effectiveness of the dishwasher, which means that it will do a better job of cleaning your dishes.
Timing: February (yearly)
Over time, a heavy film build-up from hard water minerals can become deposited on the inside walls and heating element of the dishwasher. After removing all of dishes, pans, silverware etc. and with no detergent in your dishwasher, the following should be done to remove the type of scale shown:
- Mold: Place one tablespoon of bleach in your dishwasher and then run it for a full cycle.
- Rust: Place about half of a small container of Tang brand orange-flavored drink mix and then run it for a regular cycle. The citric acid in the Tang helps to loosen hard water deposits and cleans the scale from your dishwasher.
- Stains: Place a cupful of white vinegar in your dishwasher and then run it for a full cycle. An alternative to vinegar is baking soda.
Annual dishwasher maintenance consists of 6 tasks:
- Clean filter and trap: Inside the dishwasher, the filter and trap are at the bottom where the water drains out. For most models, the filter and trap lift out so that they can be cleaned with a stiff brush.
- Clear spray arm holes: Food particle or mineral deposits can clog the hole in the spray arms. Take the spray arms out of the dishwasher, and ream the holes out with a stiff wire. Shake out any loose debris.
- Clear the “air trap”: Some models have a gap in the discharge plumbing to ensure that water does not backflow into the household water supply. If the unit has an air gap it should be checked and cleaned.
- Check and tighten any loose water hose clamps.
- Check the door seal gasket for any cracks or leaks.
- Check the pre-heating mechanism: If your dishwasher has a pre-heating mechanism for when inlet water is too cold, this should be checked in accordance with your manufacturer’s recommendations.
The benefits of treating for scale build-up are moderate. Doing this task can help maintain the performance of your dishwasher, and extend its useful life.
The benefits of performing annual maintenance are moderately high. Doing this task can help prevent damage from water leaks, maintains the performance of your water heater, and help extend its useful life.
Treating for scale build-up cost low. It is estimated that this task should only take about 30 minutes to complete, and the task is relatively easy to do. No specialized tools are required, but you will need to have bleach, Tang brand beverage mix, and either vinegar or baking soda on hand.
Performing annual maintenance cost moderate. It is estimated that this task should take about an hour to complete. You will need a cleaning brush, a stiff wire, and a screwdriver to complete this task.
25 Dishwasher Tips
Your dishwasher uses jet sprays of hot water to clean your dishes, and an electric heating element to dry them off. This article and video gives you 25 tips that will help you to reduce energy, improve performance, and extend the useful life of your dishwasher.
DISHWASHER OPERATING TIPS
1. Get the water in your sink running hot before starting your dishwasher, especially in the winter, so that your dishwasher doesn’t start running with cold water.
2. Run an empty load with a cup of vinegar in the bottom to clean out old food particles to keep your dishwasher smelling fresh.
3. Always separate your stainless steel from silver (or silver-plated) flatware, because if they touch in the wash, a reaction may occur and can cause the silver to pit.
4. Place flat pans and platters along the sides and back of dishwasher, but not in the front, where they can block detergent from the door.
5. Dishwashing by hand is less efficient and uses more water than using a dishwasher. So whenever possible, it is better to use your dishwasher, unless you have just a couple of items that can’t wait for you to create a full load.
6. Dishwashers actually work better when there is some residual food on the dishes, so just scrape them rather than pre-rinsing. But if your dishes are going to be sitting in the machine all day and dry the food on, then you will need to pre-rinse them.
7. Dishwasher detergent works best when it is fresh, so only buy what you can use up within two months, and store it in a cool, dry place . . . . Not under the sink (see costs and reviews of dishwashing detergents).
8. Make sure the forks and spoons don’t nest together. Place some handles up and others down so that all surfaces get washed.
9. Secure all plastics to prevent them from falling onto the heating element and melting.
10. Let dishes air-dry instead of using the drying feature of the dishwasher. Not using the drying feature of your dishwasher reduces its energy usage by around 50% (helpful accessory: energy-efficient dishwashers).
11. Check the temperature of the hot water at the sink adjacent to your dishwasher. Run the hot water into a cup and use a thermometer to check to see if this temperature is consistent with your dishwasher manufacturer’s recommendation for the inlet water temperature for proper performance.
12. Load plates and bowls so that the dirty side faces the water spray. Pots, pans and casseroles should angle down for the best cleaning results.
13. Watch out for utensils with long, thin handles, as they might slip through the rack and prevent the spray arm from spinning freely.
14. For multiple loads, try to keep soil levels together to get the best performance. In other words, put the heavily soiled items together in one load, and the lighter soiled items in the next load.
15. If your utility has off-peak electricity pricing, then run your dishwasher during off-peak periods to save on the cost of your electricity.
16. Run your dishwasher full, but don’t over-pack to the point that you have to re-run the load to get everything clean.
17. Test your water to see if it is “hard” and if so, you may need to add a water softener to allow your dishwasher to perform better (helpful accessory: water softeners).
18. Keep the dishwasher drain clean, to make sure food isn’t clogging it up and keeping it from draining properly.
19. Treat regularly for scale build-up, using the method that is appropriate for your particular type of scaling. You can find the recommended procedure for treating each type of scale by clicking here: treating for scale build-up.
20. Frequently clean the door seals to ensure that it closes tightly and doesn’t leak water onto the floor of your kitchen.
21. Don’t add rinse aid if already in your detergent. Some detergents already include rinse aids, so if yours does, then you are just wasting money adding it separately.
22. Arrange wineglasses carefully so that they don’t bump against either one another or the top of the dishwasher.
23. Never stack items, as the water spray won’t be able to reach the top items.
24. Use as short a wash cycle as possible which still gets your dishes clean, if your model allows you to change the length or type of wash cycle.
25. And lastly, you should perform annual maintenance as described here: perform annual maintenance. Annual maintenance includes: cleaning the filter and trap; clearing the spray arm holes; clearing the “air trap”; checking and tightening any loose water hose clamps; checking the door seal gasket for any cracks or leaks, and checking the pre-heating mechanism.
We hope these 25 tips will help you to reduce energy, improve performance, and extend the useful life of your dishwasher.
