Dishwasher Troubleshooting


Dishwasher problem solving can help save a lot of money that would otherwise be spent on hiring a repairman. There are many common issues that you can fix yourself with basic knowledge of appliances.  Here are a few common issues.

Dishwasher Does Not Work – No Lights or Water

If the dishwasher does not work when it is turned on, there are a few things to check before calling a repairman. The first thing to do is to check for a tripped circuit breaker or blown fuse. This is typically caused when too many things are running at once. If this is not the problem, check to make sure the door is securely shut on the machine. Try changing selections on the dial. Many times, these solutions will work and the machine will begin to run again. However, if they do not work, it may be time to call in a qualified person to service the machine.

Humming Motor After Start

Over the years, you may notice that your dishwasher makes new noises. This is a common, and usually normal, part of machine wear and tear. If you notice a loud humming noise, stop the machine and open the door. Check to make sure nothing is stuck in the motor and that the spinners rotate freely. Many times, a fork or knife can slip to the bottom of the machine and jam the motor.

Dishwasher Leaks

This is a common problem with older machines. It is usually caused by a worn door gasket. These can be easily replaced. Always make sure to inspect gaskets when cleaning the machine and make sure they form a tight seal. A leak could also be caused by a bad drain hose or water hose. Check all connecting hoses while the machine is running and watch for leaks. If your machine is leaking soap around the door, make sure that the correct type of detergent is being used. Many people will try to use liquid dish soap in their machine. This will produce too many suds and will cause a leak.
