How To Replace Your Dishwasher's Water Inlet Valve

How To Replace A Water Inlet Valve

With a very important job, your machine's water inlet valve is the part that is used to fill the dishwasher with the correct amount of hot water. It is normally located behind the lower access panel and will have two wires attached to it, as well as an outlet hose to the tub and a hot water inlet from the household supply.

If you're having difficulties with your dishwasher not filling, then this is the first component you will need to check for damages, leakages, or its power supply/what triggers the component into action.

If you have determined that it is in fact faulty, then below you will find the necessary instructions on how to replace a water inlet valve in a dishwasher.

What Tools Do You Need?

Most likely, you will need a philips screwdriver, a hex key screwdriver, a pair of combination pliers, and maybe an adjustable spanner.

Don't have the tools needed for this job? Why not ask a neighbour, friend, or colleague if they have some you can borrow? If not, check out our selection of repair tools. The right tools can always come in handy around the house, and a good quality set can be a good investment for years to come.

Before you make any repairs to your machine, make sure you turn off and disconnect all water and power supplies to the machine. Although you will just be accessing the lower front of the machine, you may find it easier to pull out your machine and tilt it backwards to give you more room to maneuver as well as better visibility.

Steps To Replace Your Water Inlet Valve

  • First, you will need to remove the access panel at the bottom front of the machine. This is where you will need your hex key as most likely it will be secured with hex screws, around 1/4 inch in size.

  • Once this is removed, you will see another sub panel. There will be two holes that give you access to the screws that hold in place the water inlet valve. However, this can be pretty difficult to work with as it restricts mobility and visibility. Therefore, we advise removing this 2nd panel (if your machine has this cover).

  • To do this, just remove the philips screws in the top corners of the panel. The panel can then be lifted out of the machine. Now you can fully see the water inlet valve. (If you're havinng trouble determining what part is what, look at your appliance schematic diagram that should be in the appliance's user manual. Therefore, hopefully you will be able to determine what position this particular part is in).

  • Firstly, you will see the water valve bracket below the screws that secure the inlet valve, as well as fitting which connects to the water supply. Disconnect the water supply and then remove the fitting from the valve before you proceed. Simply unscrew the fitting and put to one side for the new valve.

  • Next, unscrew the two screws that are securing the water inlet valve to the bracket.

  • Now the valve will be able to drop downj and you will have access to the component and it's connecting parts.

  • Remove the connecting wires, and then you will need to remove the outlet hose. This is usually held in place with a spring clamp. If this is the case, then use you pliers to compress the clamp so it loosens and you can shift it down the hose to release the water inlet valve. You will most likely need to twist and pull the valve out of the hose as, even without the spring clamp in place, it will most likely be a snug fit.

  • Now the valve is free, all you need to do is replace the steps above to repeat the steps above in reverse.

  • First, connect the new valve to the outlet hose. Make sure you do not twist or kink your outlet hose when doing this as that can cause water flow issues. Connect the valve by pushing it into the hose and then, again use your pliers to reposition the spring clamp around the connecting parts so it is water tight.

  • Next, reconnect the wires to the component.

  • Now you can simply replace the screws so that your water valve s securely back in place.Then replace the fitting so you can replace the water supply also.

  • Now all you need to do is secure back in place the two panels and your repair is finished.
