What is the typical life span of a dishwasher?

The average life span of a dishwasher is nine years, although that time can be extended significantly with proper care and maintenance.

What is the largest size dishwasher made for residential use?

A 30-inch (76-centimeter) dishwasher is usually the largest size available before switching to a commercial model.


What makes the spray arms inside the dishwasher rotate?

The force of the water leaving the nozzles makes the spray arms spin, just like the lawn sprinklers that kids love to splash around in.


What is the purpose of the reversible pump in your dishwasher?

A reversible pump has the ability to pump water to the spray arms and to pump water out of the machine by switching directions. Water flows into the dishwasher under its own pressure.


What is the best way to load silverware into a dishwasher?

Face spoons in separate directions to keep them from nesting together and not getting clean. Knives should be washed by hand because a dishwasher can dull the blades.

One of the most frequent complaints about a dishwasher is that some dishes do not come out clean and have to be hand washed. Now who wants to do that?

The U.S. Department of Energy's Energy Star program guidelines allow you to compare the annual energy consumption of many appliances.


What is an important feature to consider if your dishwasher is close to your living room or family room?

Noise suppression is worth the extra cost if the kitchen is close to your living room or family room. In fact, you may want the extra insulation no matter where the machine is located.


If your home has hard water, what adjustment should be made when using your dishwasher?

Hard water makes fewer suds, so you can add a little more dishwasher detergent to clean dishes better.


What can you use in a pinch if you run out of dishwasher detergent?

Never use anything but dishwasher detergent in your machine. The suds will overflow, and you could end up with a bubble bath in the kitchen.


Which of the following is NOT an option for conserving energy when using your dishwasher?
