Many Frigidaire dishwashers use a cable and pulley to activate the spring that opens and closes the dishwasher door. After continued use, the cable can get worn out or simply rub too tightly against the pulley. This causes cable vibration, which can hurt sensitive ears and make dishwasher owners worry that something is seriously wrong with their appliance.
If your dishwasher door is making noise, it's probably due to tension on the cable from the spring when you open and close the dishwasher door. As the cable moves around the pulley when you open and close the dishwasher door, the cable vibrates. This makes a loud squeaking noise that you may find irritating or disturbing.
To stop the dishwasher door from making that horrible squeaking sound, you have to reduce the friction between the spring and the cable. The first step is to make sure the cable is clean. Oil and grease on the cable can cause extra friction. In addition, the cable may need to be lubricated. If cleaning and lubricating the cable doesn't work, you may need to replace the cable.
What To Do
Open the dishwasher door then see if there is sufficient lubrication on the cable. If not, lubricate it with WD-40 or a similar household product. If the door continues to squeak, replace the cable and pulley then re-test the door. Finally, clean the new cable and pulley with unscented soap. Rub soap on both sides of the cable and the door spring. Don't be afraid to use a lot of soap. After applying soap, open and close the door several times to spread the soap throughout the door-opening mechanism.
A squeaky dishwasher door is not harmful to your dishwasher's functioning; for the most part, it is merely annoying. So, if you are short on money, you might consider waiting to fix the squeaky door. However, since the squeak is caused by excessive friction, the cable could eventually fray as a result of opening and closing the door. It's recommended that you should take care of this problem, when you can, even if you are willing to put up with it for a while.
