- Check the water supply valve: The first thing to do when a dishwasher hums but no water is coming in is to check the water supply valve. Make sure it is turned on and that there are no kinks in the hose.
- Inspect the float switch: The float switch is responsible for regulating the amount of water that enters the dishwasher. If it gets stuck, it can prevent water from entering. Check to see if it’s stuck or damaged.
- Clean the inlet valve screen: Over time, debris can accumulate on the inlet valve screen, which can restrict water flow. Remove and clean it with a soft brush or cloth.
- Examine the solenoid valve: The solenoid valve controls the flow of water into the dishwasher. If it’s faulty, it won’t allow any water to enter. Test it with a multimeter and replace if necessary.
- Check for clogs in the spray arm: A clogged spray arm can prevent water from reaching all parts of the dishwasher. Remove and clean any debris that may be blocking its holes.

Why is my dishwasher humming but not filling with water?
Possible Causes
There are a few reasons why your dishwasher may be humming but not filling up with water. One of the most common causes is a problem with the water supply. If there is an issue with the water supply, it can prevent your dishwasher from receiving the necessary amount of water to run properly.
Another possible cause of this issue is a malfunctioning valve or pump. The valve and pump work together to control the flow of water into the dishwasher. If either one of these components fails, it can lead to problems with water intake.
Water Supply Issues
If you suspect that there may be an issue with your home’s water supply, there are a few things you can check. First, make sure that your main water valve is turned on and providing enough pressure to operate your appliances.
Next, check for any blockages in the hoses or filters leading to your dishwasher. These blockages can prevent proper water flow and cause your machine to hum without filling up.
Troubleshooting Water Supply Issues:
– Check main water valve
– Ensure adequate pressure
– Inspect hoses and filters for blockages
Malfunctioning Valve or Pump
If you have ruled out any issues with your home’s water supply, it’s possible that a faulty valve or pump could be causing your dishwasher to hum without filling up.
The valve controls the flow of water into your machine while the pump helps move it throughout its various cycles. If one or both of these components fail, it can lead to problems with proper intake and distribution of water.
Troubleshooting Valve or Pump Issues:
– Check for damaged wires or connections
– Test valves and pumps using a multimeter
– Replace faulty components as needed
Other Possible Causes
If you have ruled out issues with your home’s water supply and the dishwasher’s valve and pump, there may be other reasons why it is not filling up with water. These can include problems with the float switch or inlet valve.
The float switch helps control the level of water in your machine while the inlet valve controls the flow of water into it. If either one of these components fails, it can lead to problems with proper intake and distribution of water.
Troubleshooting Other Possible Causes:
– Inspect float switch for damage
– Test inlet valve using a multimeter
– Replace faulty components as needed
