You start the dishwasher, hear it hum, and then open it to find dry dishes and no water in the bottom. A dishwasher not filling with water cannot clean anything, and running it dry is hard on the pump and heater. The good news is that the cause is often one of a few simple things.
Need a technician? Our dishwasher repair New Braunfels team fixes fill, drain and drying problems on all major brands.

Why is my dishwasher not filling with water?
The most common causes are a closed water valve under the sink, a kinked or clogged supply line, a float switch stuck in the up position, a clogged or failed water inlet valve, a door latch that is not fully closing, and a control board fault. A new install that never filled often has a closed valve or a crushed line behind the unit.
Safety first
Turn off the dishwasher’s breaker before you remove the kick panel or touch the float area. Turn off the water valve before you disconnect any line. Keep towels handy, since lines can drip.
Common causes and fixes
1. Water valve under the sink is closed
The dishwasher usually gets water from a small valve on the hot line under the kitchen sink. If someone closed it during a repair, the dishwasher cannot fill. Open it fully.
2. Kinked or clogged supply line
The line runs from the valve, under the cabinet, to the front of the dishwasher. If the dishwasher was pushed in hard, the line can kink. Hard water scale can also clog the small fittings over time.
3. Stuck float switch
The float is a small plastic dome or cylinder in the front corner of the tub. It rises as water fills and tells the dishwasher to stop. If food, grease or a utensil holds it up, the dishwasher thinks it is full. Lift it gently; it should move up and down freely.
4. Clogged or failed inlet valve
The inlet valve sits behind the lower kick panel. It opens to let water in. If its screen is clogged with minerals or its coil fails, no water flows even though the dishwasher runs. This part is replaced, not repaired.
5. Door latch not fully engaged
Most dishwashers will not fill unless the door latch tells the control the door is closed. A worn latch may let the lights come on but block the fill. A faulty latch or control can also cause other cycle problems, such as a dishwasher not drying dishes.
6. Control board or timer
If water reaches the valve and the float is free, the control may not be sending power to open the valve. This needs testing with a meter.

Frequently Asked Questions
Why is my dishwasher not filling with water?
Common causes are a closed supply valve under the sink, a kinked supply line, a stuck float switch, a clogged or failed water inlet valve, a door latch problem, or a control fault.
Where is the dishwasher water shut-off valve?
In most kitchens it is under the sink, on the hot water line. Some homes have it behind the dishwasher’s lower kick panel.
Can a stuck float cause a dishwasher not to fill?
Yes. If the float is stuck up, the dishwasher thinks it is full and will not let water in. Clean around it and make sure it moves freely.

Usually not, but do not keep running it. A dry cycle can make the pump and heater work without water.
