How to Troubleshoot a Whirlpool Dishwasher Not Filling With Water

It can be a huge inconvenience if your Whirlpool dishwasher not filling with water slows your daily chore list. You may not be able to run dishes through the dishwasher, which can cause added stress throughout your day. This blog post will discuss some common causes of why a Whirlpool dishwasher may not fill with water. We will also provide troubleshooting tips on possibly fixing the issue yourself or suggest some of the repairs a professional dishwasher technician can perform.

Whirlpool Dishwasher Not Filling With Water? This May Be Why…

Learning how to clean a dishwasher regularly will help prevent problems like a Whirlpool dishwasher not filling with water. If your dishwasher is clean and well kept, some of these common causes may be something you can troubleshoot and fix yourself. However, if the problem persists, it’s best to call a professional repair technician for help.

#1- Problem With Water Inlet Valve

Your Whirlpool dishwasher not filling with water may be caused by the washer inlet valve. This valve is responsible for supplying water to the dishwasher. If the water inlet valve is damaged or not working properly, it may not allow enough water into the dishwasher.

The water inlet valve is usually found in the front area of the dishwasher and behind the bottom access panel.

To troubleshoot and inspect the water inlet valve:

1. First, unplug the dishwasher from any electrical supply and remove the water supply line.
2. You will need to remove the lower access panel to locate the water inlet valve.
3. Once located, thoroughly inspect the water inlet valve. Look for signs of wear, cracking, or damage. Make sure there is not a build-up of mineral deposits blocking the valve, as well.
4. Inspect the area around the water inlet valve for drops of water or water damage, as this could indicate a leaking or damaged valve.

If the water inlet valve shows any of the above signs, the valve will need to be professionally replaced.

#2- Damaged Water Supply Hose

Another possible reason for your Whirlpool dishwasher not filling with water is a damaged water supply hose. The water supply hose connects to the back of the dishwasher and supplies it with water from your home’s main water line. Is your Whirlpool dishwasher not getting water? If this hose is blocked, kinked, or otherwise damaged, it may not allow enough water into the dishwasher.

To inspect and troubleshoot the water supply hose:

1. Locate where the water supply hose is connected to your Whirlpool dishwasher.
2. Check to see if there are any visible signs of damage to the hose, such as holes, cracks, or leaks.
3. If there is any visible damage to the water supply hose, it will need to be replaced by a professional repair technician.

#3- Faulty Float Switch

Is your Whirlpool dishwasher not filling with enough water or not filling with water at all? The float switch may be damaged, stuck, or malfunctioning.

The float switch is a small device located inside the dishwasher that senses how much water is in the dishwasher and tells it to stop filling when it reaches a certain level. If this switch is damaged or not working properly, it may not tell the dishwasher to stop filling, causing it to overflow.

To inspect and troubleshoot the float switch:

1. Locate the float switch. It is usually located near the bottom of the dishwasher tub, attached to the side.
2. Inspect the float switch for any signs of damage or corrosion.
3. Make sure the float switch can move up and down easily. If needed, remove any build-up of debris from around the float switch.
4. If the float switch is damaged or does not move freely, it will need to be replaced by a professional dishwasher technician.

#4- Malfunctioning Door Switch

A malfunctioning door switch may be the cause of your Whirlpool dishwasher not filling with water. The door switch is located on the dishwasher door and prevents the dishwasher from running when the door is left open. If this switch is damaged or not working properly, it may prevent the dishwasher from starting or filling with water.

To inspect and troubleshoot the door switch:

1. Locate the door switch. It is usually located near the top of the dishwasher door on the frame.
2. Inspect the door switch for any damage or corrosion.
3. Make sure the door switch is able to move freely. If needed, gently remove any build-up of debris from around the switch.
4. If the door switch appears damaged or does not function correctly, it will need to be replaced by a professional.

#5- Other Faulty Dishwasher Components

If you have followed these troubleshooting steps and the dishwasher isn’t filling with water, there is likely a problem with a malfunctioning dishwasher part. If you have a Whirlpool dishwasher that won’t fill, we recommend calling a professional to take a look at it.
