Narrow it down
What this symptom can tell you
The cycle does not begin and no water is heard
The door may not be latched, a delay may be active, or the cycle may not have been started fully.
The machine hums but little water enters
The water valve, hose, household pressure, or an internal inlet path may be restricted.
The problem began after plumbing work
A supply valve may be closed, the line may contain air, or the connection may need rechecking.
These patterns narrow the next check; they do not confirm a failed part. Use the exact model number and any displayed code before ordering parts or authorizing repair.
Try these checks in order
Exact controls and access points differ by model. Stop when a step does not match your appliance or manual.
- 1
Open the water shutoff
Find the dishwasher water valve under the sink and confirm it is fully open. Do not force a corroded valve.
What you want: The handle is open and no leak is visible. - 2
Close the door firmly
Remove utensils or racks that block the door and close it until the latch engages.
What you want: The door sits flush and latches without force. - 3
Cancel Delay Start
Check the display for a delay time or Control Lock. Use the model manual to cancel it.
What you want: No delay or lock indicator remains. - 4
Clear the visible float area
Some models have a small float in the tub. Remove loose debris around it without unscrewing or forcing it.
What you want: The float moves freely if the manual identifies it as owner-accessible. - 5
Check household water
Run the kitchen faucet. Very low water pressure or plumbing work can affect dishwasher filling.
What you want: Cold and hot water flow normally at the sink.
Most common categories
Possible causes to consider
- A closed or partly closed dishwasher water-supply valve.
- A kinked, crushed, frozen, or leaking inlet hose.
- A door that is not fully latched or a control/delay setting.
- Low household water pressure or an interrupted supply.
- An inlet valve, float, sensor, wiring, or control issue requiring service.
Stop and arrange help when
- The supply valve, hose, or connection leaks.
- The dishwasher keeps filling after it is turned off.
- The float or inlet parts require disassembly.
- Water reaches electrical components.
If the problem remains
Find the full model number. Open the official manual, check for a recall, and describe which checks you completed before contacting service.

Common questions
Dishwasher not filling: FAQs
Does a dishwasher fill all the way to the top?
No. Modern dishwashers use a controlled amount of water that usually stays below the heating and spray areas. Compare only with the model manual, not an assumed water level.
Why does the dishwasher fill slowly?
A partly closed valve, restricted hose, low pressure, or developing inlet issue can slow filling. Stop if a hose or fitting leaks.
Can the door latch prevent water from entering?
Yes. Many dishwashers will not begin filling unless the controls confirm that the door is closed and latched.
