How to replace the A962478NU solenoid valve in a Sensorflow 21 or Markwik electronic tap

Replacing the A962478NU Ideal Standard / Armitage Shanks solenoid valve can seem quite intimidating. You can opt to call an electrician or plumber to help fix your shower. Here are the steps for changing a solenoid valve for taps.

1. Never forget to turn off both hot and cold water supplies before starting. Unscrew and remove the control box cover.
2. Take out the PC electronic board and disengage it from the plug.

3. Take out the red and black wires from the solenoid valve by removing its four screws. Then slowly extract the valve. Check to see if the valve diaphragm is removed from the chamber. If not, please make sure to remove it as well.
Note: Water will seep out, hence it will be helpful to have a small container and a towel.

4. Install the new Ideal Standard A962478NU solenoid valve by gently pushing and positioning it properly in the chamber. Screw the four screws in and tighten.

5. Reconnect the valve to the red and black sensor wires.
6. Plug the PC electronic board and situate it back in place in the control box.

7. Screw back the control box cover and tighten it.
8. Turn the hot and cold water supplies on and test if the replacement is a success.

How does the Ideal Standard A962478NU Work?

A962478NU is a solenoid valve for Armitage Shanks Sensorflow tap. A solenoid can be an electromagnet or an inductor that produces a magnetic field or obstructs alterations in electric currents. It is a coil shrouded round a metal-like core to generate – when an electric current flows through – an even and stable magnetic field.

The electric shower valve part using a solenoid to manage a valve’s water flow is called a solenoid valve. A magnetic field is formed through the movement of an electrical current that enables it to work. The A962478NU can be made of aluminum, brass, plastic, or stainless steel. Seals will depend on the fluid where this type of valve will be used.

The Ideal Standard A962478NU is a one-way solenoid valve. It consists of two gates for the water flow. Water flows from one to the other when it is open and restricted when closed. A solenoid valve that is “normally open” means the solenoid within is not energized while the valve is open. A “normally closed” solenoid valve means that the electric current is not passing through the valve while it is closed.
