Viking Dishwasher Water Inlet Valve Concerns

If your Viking dishwasher is not filling with water, it will obviously not be able to wash your dishes. This is a fairly common problem that can occur due to frequent or regular use. This is good news since it means that there are a few common causes that will not cost too much to repair. Here are some of the most common reasons why your dishwasher may not be filling with water.

Water Supply

Before you worry about potential problems with your dishwasher, you should check your water supply. Make sure that the water to your home has not been shut off and check the hose that connects your dishwasher to the water supply.

Water Inlet Valve

This valve, as the name suggests, allows water to enter the dishwasher. It also ensures that the right amount of water enters and it is controlled by an electronic control or timer. The valve is usually located on the lower left side of the dishwasher. Disconnect your dishwasher from the power and water supply and look for any signs of damage or excessive wear. If it is worn, it will need to be replaced before you use your dishwasher again.

Door Switch

The door of your dishwasher has a switch that lets the control panel know whether the door is open or shut. If this switch malfunctions, the dishwasher will interpret this as the door being open and, as a result, it will not fill with water. The door switch will need to be tested with a multimeter in order to determine if it is indeed faulty. If it is faulty, replacing the door switch will resolve the problem.

Float

The float is a safety device that prevents your dishwasher from over-filling with water. The float rises along with the water level. So, when the water reaches a certain level, it will cause the dishwasher to stop filling. To test the float, you will need to unplug the dishwasher, remove the cover over the float and manually lift the float and allow it to drop a few times. If it does not move freely, there could be a foreign object causing an obstruction. If the float itself is worn or damaged, it might need to be replaced.

Float Switch

This switch is connected to the float. When the float reaches the appropriate level, it will turn off the water inlet valve by means of the float switch. The switch will need to be tested using a multimeter and, if faulty, it will need to be replaced.
