There could be a few reasons why your dishwasher won't fill with water. It could be an improperly positioned drain hose, a door that's not fully closed, a water supply that's turned off or an overfill protection float that's got something stuck in it.
Be sure your water supply valve is not leaking or blocked. If there is a leak coming from the valve, try to fix it by ensuring that all connections to the valve are secured tightly. To tighten, place a bucket beneath the valve in case any water escapes and use a wrench to secure all connections to the valve.
If your Dishwasher is making a humming sound but is not filling with water, this could be due to the pump motor not running for a week or longer. This can cause the Dishwasher pump seals to dry out and stick. Operating the Dishwasher at least once a week keeps the seals from drying out and sticking.
Signs pointing to a faulty inlet valve include: Leaks that fill the dishwasher when it's off. Inadequate water for a cycle. The dishwasher fills too slowly or not all.

A mixture of equal parts baking soda and vinegar may unclog dishwasher drains. Pour the solution into the basket at the bottom and let it sit for 15 minutes. Then, pour hot water down the basket and run the rinse cycle.
Pump and motor issues: The circulation pump pulls soapy water from the drum and shoots it throughout your dishwasher. If the pump gets clogged by a large food particle or long-term build-up, it will stop circulating and compressing the water. Additionally, the motor can also wear out over time.
Some models require you to shut off the power to the dishwasher either by unplugging it or shutting off the circuit breaker. Others are reset by pressing and holding the Start/Reset button on the control panel, then waiting a few moments before attempting to start a wash cycle.
The most common reasons your KitchenAid dishwasher has no water are a broken detergent dispenser, defective electronic control board or a clogged water valve.
About five seconds after you start running a dishwasher cycle, the drain pump will start making a low humming noise. This will be due to a piece of glass blocking the impeller from turning, resulting in the dishwasher pump not working properly. When this happens, you'll need to remove the blockage.
A malfunctioning dishwasher float
Your dishwasher float is located on the bottom of your appliance's tub. This component is designed to prevent your machine from filling up with too much water. If the float isn't working correctly, it could be telling your dishwasher not to fill up when it actually needs to.

The motor drives an impeller to force water out of the drain hose. If the motor runs during the drain cycle, check for a blockage in the drain line. If the motor won't run during the drain cycle or if it just hums when it should be running, the pump and motor assembly might need to be replaced.
It could be an improperly positioned drain hose, a door that's not fully closed, a water supply that's turned off or an overfill protection float that's got something stuck in it.
