Frigidaire Dishwasher Troubleshooting: Water Doesn't Spray

Lee Morgan

Your Frigidaire dishwasher makes cleanup after dinner so much more pleasant. Little need arises for the manual scrubbing and scraping of dishes in hot soapy water in the sink as long as the dishwasher is working properly. What makes these convenient appliances effective is their ability to direct hot streams of water onto the dishes, stripping them of stuck-on foods and sanitizing them for future use. If the water in your dishwasher isn’t spraying, the job will not get done.

Water Inlet

Get your dishwasher working so you can stop doing dishes by hand.

Every dishwasher, including your Frigidaire, has a water inlet valve. If this valve is not functioning properly, the correct amount of water will not get into the machine. The inlet valve is typically located behind the lower access panel and consists of a rubber tube that leads from the water line to the dishwasher. Typically visible wires are attached to it. If the valve isn’t allowing the water in because it is defective, it will have to be replaced or the water will not reach the machine and spray.

Float Switch

As the dishwasher fills up, a device known as the float switch determines when the level is high enough. A floating cylinder that rises as water fills the washer aids the float switch in this task. If this cylinder is stuck in the lifted position, or if the float switch itself is malfunctioning, water will not enter the machine and therefore it will not spray the dishes clean. You can test the continuity in the float switch to see if it is broken and needs to be replaced, and you can check the cylinder to ensure it moves freely up and down in the machine. It is located in the floor of the main dishwasher compartment.

Dirty Spray Arm

Even if the flow of water is normal to the machine, the flow can be disrupted at the spray arm, which is the rotating device that shoots water from many tiny openings to wash the dishes. Sometimes food particles, detergent buildup or sediment from hard water can clog these openings and prevent the water from spraying properly. When this happens, you’ll need to clean the spray arm. According to the Frigidaire website, your dishwasher’s spray arm can be removed easily by removing the nut that secures it by hand and lifting it out. You should use warm soapy water and a soft brush to clean the arm. You may need to use a toothpick or other small device to clear the holes.

Door Switch

If your dishwasher won’t start and therefore isn’t spraying, it could be because of a faulty door switch. A safety device located on the inside door facing prevents the dishwasher from running until the door is shut completely to prevent leaks. You may have to replace this switch if it is indicating the door is ajar when it is not.
