How to Replace a Dishwasher's Water Inlet Valve


If you are having problems with the hot water going to your dishwasher, you may need to change your machine's water inlet valve. The valve controls the water flow to the machine, and replacing it is a simple procedure anyone can do with some step-by-step instruction.

Things You'll Need

  • New water inlet valve
  • Pan
  • Pliers
  • Unplug your dishwasher for safety reasons, and double check that it is no longer connected to its power source. Depending on your dishwasher, you may have to turn off its power from the circuit breaker or remove a fuse. Shut off your water valve and turn off the water supply to your machine. You may have a hose that runs from the faucet.

  • Find the panel underneath your dishwasher, often referred to as the kickplate panel. Some panels need to be unscrewed from their position; others fold down because they are hinged to the machine.

  • Locate your inlet valve. In most machines, it is located in the left or right corner of the panel and should be visible to you. Your inlet water valve will have hoses connected to it--one that takes water to the machine and another that takes water away. This is a good time to check that your hoses are in good condition, not corroded or kinked. Take the hoses off the dishwasher intake valve. You should probably place a container underneath before disconnecting in case there is water left in the hoses.

  • Disconnect the wires from the inlet valve. Write down where the wires go so there are no problems reconnecting later. Not using the wires but the connectors instead, disconnect the wires. You may have to use pliers to do this.

  • Unscrew the inlet valve, remove it, and save the screws. Now, place your new water inlet valve where the old one used to be, and screw it in place with the old screws.

  • Replace the hoses and wires. You may want to turn on the water, and check if the hoses are secured in place and not leaking. Put panel back in place and turn on the power to the dishwasher.

Tips & Warnings

  • It is most important to be safe. Be sure to disconnect both the hoses and the electrical power to your dishwasher before you begin work.
