How To Test The Timer Motor In Your Dishwasher


The timer motor in your dishwasher can cause several different problems with how the machine operates. This one little part can cause a lot of problems, so it is a good place to start when the dishwasher malfunctions.

What troubles can the timer motor cause?

  • The dishwasher doesn't work at all – no lights, sound or water.
  • The dishwasher cycle doesn't finish.
  • The dishwasher detergent cup doesn't open.
  • The dishwasher cycles are running too long.
  • The dishwasher isn't getting the dishes clean.

If you are experiencing any of the above problems, it is time to test the timer motor.

How do you test the timer motor?

To make this process a little easier, use your owner's manual to locate the control panel in the dishwasher. This will help eliminate some unnecessary steps because some units have a direct access panel to the control panel and others require you to remove the entire inner panel of the dishwasher.

Tip: If you do not have a copy of your owner's manual, go online and search for one using the make and model number.

Step 1: Disconnect the Power

Unplug the dishwasher or turn off power at the breaker panel or fuse box.

Step 2: Access the Control Panel

Begin by removing any external screws that are necessary to access the control panel. Usually, there will only be two screws located around the door latch.

Open the dishwasher and remove the screws on the internal door panel. Put the screws in a small jar or glass to avoid losing them while you work. Start with the screws closest to the top of the dishwasher door. On some models, the upper two screws are all that is needed to be removed to access the control panel. If that does not work, continue removing the screws along the sides of the door.

Note: Do not remove the screws that connect the door to the hinges. These screws should not need to be removed to open the panel.

Step 3: Test the Timer Motor

You should now see the timer motor. It looks like a square box with a cylinder on one side. Locate the two wires that extend from the round motor housing and follow those wires to where they connect to the terminals.

Grasp the connectors with needle-nose pliers and carefully disconnect them. Look for any corrosion on the connectors and terminals. If you see corrosion, clean them with a bit of white vinegar.

Use a multitester to test the motor. Set the multitester to the X1000 setting, touch each probe to the each wire and get your reading. Your owner's manual should include information regarding the appropriate reading for your dishwasher, but generally, it should be between 2,000 and 3,500 ohms. If the reading is off, the motor should be replaced.

Following these steps will help you determine if the problems you are experiencing are caused by the timer motor. If you do not feel comfortable completing this task or are in need of replacement assistance, contact your local appliance repair technician for dishwasher repair.

Exploring Refrigerator Technology

Hello, my name is Shantay Vexors. I am crazy about all of the advancements made in the refrigerator industry in the last few years. Refrigerators revolutionized the way people shopped and stored food for later consumption. Prior to refrigeration, food had to be preserved with canning, curing, drying and pickling practices. Today, we always have fresh food on hand. Furthermore, the food can last more than a week in the refrigerator. Fridges often come with a filtered water dispenser and ice maker on the front. These helpful appliances also offer convenience features like menu storage and shopping list creation using smart technology. I will update my site often with more information about refrigerator technology. I will discuss the various advancements made to these appliances as they are developed. Please visit often.
