My dishwasher will not fill with water... yes the water is turned on! :(

There may be filter insert at the solenoid valve, where your incoming water flex pipe connects to. Unscrew the bottom kick plate, unscrew the water supply and see if you can see the filter. If dirty, remove it, clean it and reinstall.

Other than that make sure water is coming through your supply line all the way to the D/W. Check if your D/W is plugged in and its breaker is in ON position in service panel. If you have pig tail elec. Connection between D/W and wall, and it is plugged into GFI receptacle, make sure it is not tripped. It is a good practice to trip it manually and reset it.

Otherwise, you may be in need of appliance service call.
