Chosen Solution
I bought a used Kenmore dishwasher, and it wont fill with water, but will run through the whole cycle with no water. Although, if we pour 3 cups of water into the bottom of the dishwasher, then start the load, it will actually start filling with more water, and will fill with water again for the rinse cycle. Is there a good chance our dishes are getting properly cleaned? And why is this happening?
Solution 1: Water Inlet Valve The water inlet valve opens to allow water to enter the dishwasher. If the water valve is clogged or defective, water will not flow into the dishwasher. Water inlet valves are not repairable—if the valve is defective, you must replace it. Solution 2: Float Switch The float switch actuates in order to prevent the dishwasher from overflowing. If the float switch is defective or stuck, it might not stop the dishwasher from overflowing. If the float switch is defective or stuck, it might not stop the dishwasher from overflowing. If the float switch is defective, replace it. Solution 3: Water Supply Problem Over time, calcium deposits can build up in the water supply valve or in the small filter screen inside the water inlet valve. If the water inlet valve is clogged with sediments, the dishwasher won’t fill properly. Before working on the water line, first shut off the water supply. Inspect the valve to determine if is clogged. In addition, check the water pressure to the valve. The water inlet valve requires at least 20 psi to function properly.
I have the same problem. I replaced the inlet valve and the float switch. For some reason I have to prime the dishwasher by adding a bit of water first. Then it will fill the rest of the way as usual. Can’t find the solution on the internet. Just like the replies here, everyone points to the inlet valve or float switch. Anyone with a real solution to this particular problem is incouraged to post it. I am continuing on with my troubleshooting. If I find the answer I will report back.
I’m having this same issue on a GE PDT750SSF8SS. I had to pour some water into the washer to prime it to get the water running.
