If the Dishwasher is not filled with water, make sure the door is completely closed to activate the door switch. The issue could be a faulty door switch, but there’s no one-size-fits-all solution to why this happens; there are a variety of factors to consider. Many alternative remedies need electrical or plumbing knowledge, and determining the problem of a dishwasher not getting water isn’t usually straightforward. In general, it’s a good idea to hire an expert to look at it. Here are some of the most common causes of a dishwasher not receiving water.
The dishwasher may be unable to receive water due to a faulty water inlet valve
The water inlet valve is the most common cause of a dishwasher not receiving water. The water inlet valve is regulated by a timed or electronic control and is used to fill the dishwasher with the right amount of hot water. This prevents water from entering the dishwasher if the water inlet valve fails to open. This valve, which is normally located behind the bottom access panel on the front of the dishwasher, has a hose that connects to the waterline as well as a hose that leads to the dishwasher’s tub. Before starting the dishwasher, unplug it and disconnect the water supply if you want to inspect the water inlet valve.
- Find the water supply valve. It’s normally found on the dishwasher’s lower left side. To find it, you’ll need to remove the lower access panel.
- Visually inspect the water inlet valve for any evidence of damage, wear, or cracking.
- If any of the symptoms listed above appear on your valve, it will need to be replaced.
A faulty float switch could be causing the power outage
A little plastic fragment will float upward as water enters the dishwasher during a wash cycle. The float switch that signals the water inlet is located beneath the float at the bottom of the dishwashing tub. The water inlet valve may not open if that switch is not connected or is faulty, and the dishwasher will not get water. Check that the float arm mechanically activates the float switch when the float is lifted to the height of the top of the water heater by unplugging the dishwasher. Also, double-check that the wires coming out of the float switch aren’t frayed.
A faulty door switch could be the source of the problem, preventing the dishwasher from filling with water
A door switch is a basic on/off switch that prevents the dishwasher from running while the door is open. The dishwasher will not fill with water if the door switch is broken. You’ll need a multimeter to test the component’s probes if you wish to check the door switch.
- To begin, turn off the dishwasher.
- Remove the inner door panel by opening the door and unscrewing it.
- You’ll see the latch assembly at the top of the door when you remove that panel. Close the latch and check to verify if both switches are activated when the catch is inserted into the latch assembly by hand.
- If this is the case, use a multimeter to verify the two switches for continuity.

The operation of the drain valve is affected by a broken drain solenoid
A drain solenoid controls the dishwasher drain valve. This solenoid will not allow the drain valve to function if it is malfunctioning, and this could be the cause of the dishwasher not receiving water. Check the drain valve and the solenoid to make sure they’re both in good operating order. Replace the solenoid with a new OEM (original equipment manufacturer) part if it’s broken.
It’s possible that a broken water supply line is at blame
Check the water supply and the water inlet hose under the sink for any kinks and make sure it’s connected properly. Make sure the hose tap is open—if you’re not sure which position is open and which is closed, turn it and run the dishwasher to see if the problem goes away.
