If you don't have water going to your dishwasher, there may be a blockage in the line to the dishwasher. Shut off the water under the kitchen sink, remove the dishwasher line and then turn on the water to the valve, directing the flow into a small bowl. If water comes out, then you may have either a plugged filter under the dishwasher or a bad solenoid valve on the dishwasher. In either case, contact an appliance repairman or licensed plumber to fully evaluate your dishwasher’s problems, and determine the best course of action. If the line is blocked to the valve, you will need to start removing piping back to the meter to find the block.
