Preventative Maintenance Tips
Prevention is always better than remedying problems after they have occurred. By adhering to a routine maintenance schedule, you can keep your Whirlpool dishwasher humming along smoothly.
Regular Cleaning
Make it a habit to clean the filters, spray arms, and interior of the dishwasher to minimize clogs and buildup.
Check Water Supply Regularly
Regularly checking your water supply valve and line can prevent issues down the line. Make sure there are no kinks in the line and that the valve is functional.
When to Call a Professional
If, after performing the aforementioned checks, your dishwasher is still humming but not filling with water, it may be time to call in a professional. A technician will have the skills and tools necessary to pinpoint the issue that may not be apparent to the average homeowner.
Signs You Need Professional Help
Consider reaching out to a professional if:
- The humming persists even after all troubleshooting has been completed.
- You notice leaks or water pooling around the dishwasher.

What could cause my Whirlpool dishwasher to hum without filling with water?
If your Whirlpool dishwasher is humming yet not filling with water, there may be a few potential culprits. One common issue is a clogged or kinked inlet hose. When the inlet hose is obstructed, water cannot flow into the dishwasher, which results in a humming sound as the appliance attempts to fill. It is advisable to inspect the hose for any bends or debris that might be causing this blockage.
Another possible reason for this issue could be a malfunctioning water inlet valve. This valve regulates the water entering the dishwasher, and if it is damaged or defective, it might make a humming noise while failing to allow water to fill the machine. To troubleshoot this, consider checking the valve for any visible signs of wear and tear, and test it for electrical continuity with a multimeter.
How can I fix a clogged inlet hose?
Fixing a clogged inlet hose on your Whirlpool dishwasher is a relatively straightforward process. First, you will need to turn off the water supply and disconnect the hose from the dishwasher. Inspect the hose for any visible blockages or kinks, and if necessary, clean it out with warm water. A soft brush can help remove buildup that may be obstructing the water flow.
Once the hose is cleared, reattach it securely to the dishwasher and the water supply. Be sure to tighten any connections to prevent leaks. After reconnecting everything, turn the water supply back on and run the dishwasher to see if the issue is resolved.
What should I do if the water inlet valve is faulty?
If you suspect that the water inlet valve is faulty, you will need to replace it. Start by unplugging your dishwasher and shutting off the water supply to prevent any accidents. The water inlet valve is typically located at the bottom of the appliance near the front. Remove any covering or panels to access it, and disconnect the electrical wiring and water line attached to the valve.
Once removed, take the faulty inlet valve to a home improvement store or search online for a suitable replacement model. After obtaining the new valve, reverse the removal process by installing it in the same position, reattaching the electrical wiring, and water line. Finally, plug in the dishwasher and turn on the water supply before testing to ensure everything is functioning properly.
Is there a way to check for electrical issues in my dishwasher?
Indeed, you can check for electrical issues in your Whirlpool dishwasher using a multimeter. First, make sure to unplug the dishwasher from the wall outlet for safety. You can then check the power supply that’s coming into the dishwasher. Navigate to the junction box, which is generally located at the bottom of the appliance, and confirm that the wires are secure and not damaged.
Next, test the water inlet valve using the multimeter. Set the multimeter to the appropriate ohms setting and check the terminals on the valve for continuity. If there’s no reading or if the reading is outside the recommended range, the valve is likely faulty and needs replacing.
Could a malfunctioning float switch be the reason for the issue?
Yes, a malfunctioning float switch can certainly cause your Whirlpool dishwasher to hum but not fill with water. The float switch is a crucial component that detects the water level inside the dishwasher and informs the control board when to allow water to fill the appliance. If the float is stuck or the switch is defective, the dishwasher may falsely believe that it is already filled and thus won’t engage the water inlet.
To troubleshoot this issue, check the float inside the dishwasher for any obstructions that may be preventing it from moving freely. Clean any debris and ensure the float can rise and fall without resistance. If the float appears to be functioning normally but the issue persists, it may be time to replace the float switch.
How can I tell if the door latch is causing the problem?
The door latch of your Whirlpool dishwasher can also play a critical role in the machine’s ability to fill with water. If the door latch is malfunctioning, the dishwasher may think the door is open, which will halt the filling process. To check for this issue, inspect the latch for any visible damage or misalignment. Ensure that it is engaging properly when the door is closed.
If you find that the latch is damaged or not working properly, you will need to replace it for the dishwasher to function correctly. Consult your user manual for instructions on accessing and replacing the door latch safely. After the latch is fixed or replaced, try running the dishwasher again to check if the filling issue is resolved.
When should I contact a professional for help?
If you’ve gone through basic troubleshooting steps but your Whirlpool dishwasher continues to hum without filling with water, it may be a sign of a more complex issue. Electrical or control board problems can be challenging to diagnose and fix without the appropriate tools and expertise. If you’re unsure or uncomfortable performing further inspections, it’s best to seek professional assistance.
Additionally, if your dishwasher is older or has multiple issues, consulting a certified appliance repair technician may save you time and effort in the long run. They can conduct a thorough diagnosis and provide recommendations on whether to repair the existing unit or consider a replacement.
