If your Whirlpool washing machine just hums, don’t worry. In this detailed guide, we’ll be discussing the causes of this issue and giving you steps on how to resolve them…

Whirlpool Washing Machine Just Hums — How To Fix

If your Whirlpool washing machine just hums, here are the issues to look for…

1. Machine Isn’t Filling

If your Whirlpool washing machine just hums instead of starting a cycle, it could indicate the drum hasn’t been filled with water. Here are the most common causes of this issue…

Water Faucets Aren’t On

If your washer isn’t filling, the first thing to do is check to ensure that the COLD and HOT water supply faucets are fully opened. In order to prevent any restriction of water flow, ensure that the hoses aren’t bent or kinked.

Inlet Filters Are Dirty

Your Whirlpool washing machine has two filters in the inlet ports at the back of the cabinet. Over time, dirt from your water supply can accumulate in the filters and clog them.

To fix this issue, you’ll need to turn the water faucets off and disconnect the inlet hoses. The inlet filters can be pulled out with needle-nosed pliers and rinsed in a sink.

Water Inlet Valve Is Damaged

The inlet valve assembly controls the water that flows into the drum. If your washing machine is overfilling or not filling at all, it could be the result of a failed valve. You’ll need to replace the inlet valve to fix this issue. Read this article for steps on how to do this: Whirlpool Washing Machine Error Codes.

2. Machine Hasn’t Drained

Another thing which can cause your washing machine to just hum is a failed drainage system. The following are the things which can prevent your washer from draining properly…

Pump Filter Is Clogged (Front Loaders)

If your front loader washing machine isn’t draining, the first thing you should do is check the pump filter. The filter is located at the lower front section of the machine. Over time, lint and dirt from clothes accumulate in the filter and can clog it.

Pump Has Failed

Another thing which can prevent your washer from draining is a failed drain pump. Before rushing to replace your washer’s pump, you’ll need to test it using a multimeter. Read this article for a detailed walkthrough: Whirlpool Washing Machine Stuck.

The impeller is a plastic fan-like piece inside the motor. The helps move the water through the pump. If it gets damaged, the pump will not function properly. Follow the steps below to inspect your drain pump for this fault…

Step 1. Make sure to disconnect your washing machine from the electrical outlet before starting this procedure in order to prevent electrocution.

Step 2. Go to the front of your washer, then loosen the three bolts holding the lower front access panel using a 1/4 inch nut-driver. Pry the panel off the machine and set it aside.

Step 3. Place some towels and a container on the floor in front of the pump filter knob. Turn the filter knob, then let any water stuck in the machine drain out. Set the pump filter aside.

Step 4. Pry the cap off the drain pump assembly, then unplug the wire connector attached to it.

Step 5. Using pliers, release the spring clamps holding the two hoses to the drain pump assembly. Disconnect each hose from the pump (keep a rag nearby in case water spills out).

Step 6. With a 1/4 inch nut-driver, loosen the bolts holding the pump assembly to the bottom of the cabinet. Carefully pull the pump out of the cabinet.

Step 7. Insert a flat-blade screwdriver into the pump filter opening, then try rotating the impeller blades. If the blades don’t turn or are broken, you’ll need to replace the entire pump assembly.

Step 8. If the impeller blades are in good condition, reinstall the drain pump in the cabinet, then apply the bolts using your 1/4 inch socket wrench.

Step 9. Reconnect the two hoses to their appropriate ports on the drain pump. Use your pliers to slide the retaining clamps into place.

Step 10. Plug the wire harness back into the drain pump terminal, then snap the cap back on. Put the pump filter back in place.

Step 8. Insert a flat-blade screwdriver into the port aligned with the pump motor. Using the screwdriver, try rotating the impeller blades. If the impeller doesn’t rotate or the blades are damaged, you’ll need to replace the drain pump assembly.

Step 9. If the impeller is in good condition, remount it on the outer tub, then tighten the bolts using the 5/16 inch nut-driver.

Step 10. Plug the wire connector into the drain pump. Reconnect the two hoses to their corresponding ports on the pump. With your pliers, slide the retaining clamp into place.
