HOW TO REPLACE A DISHWASHER WATER INLET VALVE INSTALL

Note 4: Depending on the access and physical constraints it may be easier to install the hot water pipe first and then the fill pipe. If your clamp is not tight replace it with a hose clamp that uses a screw (worm drive) for tightening, as shown in Figure 4. Note 3: In some cases the clamp will be damaged or will not spring back to its former position and hence will not seal the fill hose to the barb on the inlet valve. Install the fill hose, sliding the clamp back up the hose.Install the new inlet valve in the same manner as the original.If that is the situation with your dishwasher remove the screws or bolts that hold the inlet valve to the bracket and reinstall the bracket in the same manner on the replacement inlet valve. Note 2: In some cases the mounting bracket will not be included with the replacement inlet valve. Remove the screws and save them as the replacement inlet valve will not have mounting screws included. The inlet valve itself will be fixed to the frame of the dishwasher using a mounting bracket that has 2 to 4 screws holding it in place.Whichever method your manufacturer used the fill hose must be removed. In some cases the fill hose may be connected using a hex fitting similar to the inlet hose, but most likely a different size. Using a pair of pliers grasp both ends of the clamp and squeeze inwards while sliding the clamp down the hose. In most cases the fill hose that is connected to the inlet valve will have a spring clamp, as shown in Figure 3.It is wise to have a large sponge and some rags available to pick-up the spilled water to avoid any damage. Note 1: There will be water in the line and it will most likely spill out when the hex fitting is released. Using a wrench, or pliers loosen the fitting and pull the pipe or hose away from the inlet valve: Most will be connected using a hex fitting. Newer dishwasher installations will have copper piping or a flexible stainless steel braided hose connected to the inlet valve, while older units will have a rubber hose.Figure 2 - Hose, pipe and electrical connections to dishwasher inlet valve Identify which wire goes to which terminal before removing the wires.įill hose, hot water pipe and wiring connections are detailed in Figure 2 below. DO NOT pull on the wire itself as it is more than likely that you will pull the wire out of the connector. To remove the wires use a pair of needle nose pliers and pull on the connector that is attached to the end of the wire. In most cases the wires are connected to the inlet valve using quick connect terminals. Remove the wires that power the solenoid portion of the inlet valve.

Each manufacturer's inlet valve looks somewhat different (a sketch of a basic unit is shown), and the mounting configuration could place the outlet on the top or side, however you should be able to identify the unit, quite easily. This is where the incoming water supply to the dishwasher is automatically turned on and off depending on the dishwasher's working cycle. Installed in the front area of the opening will be an inlet valve, see Figure 1.This panel provides access to most of the dishwasher components.

The panel is either held in position with screws and is removable or is hinged to allow it to fold downwards.

Turn off the water supply valve to the dishwasher (usually located under the sink), or disconnect hoses from the faucet.

Turn off the power using the appropriate method.

If your dishwasher is not filling, the problem could be a defective inlet valve. A solenoid powered valve is given commands from the timer control and opens and closes the valve appropriately. The dishwasher's inlet valve controls when hot water is delivered to the dishwasher.
