How to test and change the electrovalve of a steam plant?

Aug 03, 2023, 14:42pm

The steam generator is an external tank connected to the iron which heats the water and produces the steam necessary to hydrate the fibers of the fabric. It allows you to smooth it out in a single pass of the iron.

Such an action is made possible thanks to the solenoid valve located inside the steam generator. Indeed, it is a part whose role is to manage the flow of water entering and leaving when you press the steam switch on the iron.

With time and use, this part may fail. If you notice signs like:

  • the steam generator no longer produces steam,
  • the steam generator leaves water stains on clothes,
  • you have white marks on your clothes,
  • your steam generator makes a lot of noise.

If these symptoms are noticed, it is possible that the problem is with this part. It is therefore necessary to test it before changing it and replace it if it is faulty.

It is a simple operation that you can do by yourself.

In a steam generator iron, the solenoid valve is located inside the boiler outlet in most cases.

How to test and change the electrovalve of a steam plant?

DISASSEMBLE YOUR DEVICE

  • Place your device on a workbench.
  • Remove the water tank located at the front of the steam generator.
  • Turn your device over and locate all the screws holding the protective cover in place.
  • Unscrew them, using a screwdriver or another suitable tool and put the screws in a small container so that you can find them easily.
  • Separate the upper part from the lower part.

TEST THE SOLENOID VALVE BEFORE REPLACING IT

  • Locate the location of the solenoid valve.
  • Remove the connector on it.
  • Calibrate a multimeter in the ohm position, whose symbol is Ω.
  • Place the test probes of your multimeter on each terminal of your solenoid valve. You should find a value between 1 and 6 ohms. If so, your valve is good.

REPLACE FAILED SOLENOID VALVE

  • Take a suitable spanner and unscrew the fixing nut counterclockwise.
  • Remove the water hose.
  • Remove the coil from the solenoid valve.
  • Then unscrew the valve body.

REINSTALL NEW SOLENOID VALVE

  • Replace the new solenoid valve. To do this, first screw in the valve body using pliers.
  • Insert the solenoid valve coil, then replace the fixing nut with a suitable wrench in a clockwise direction. Make sure you have a good tightening.
  • Replace the water hose.
  • Replace the connector on the solenoid valve.

REASSEMBLE YOUR DEVICE

  • Glue the upper part to the lower part.
  • Replace the retaining screws using a screwdriver or other suitable tool.
  • Replace the water tank located at the front of the steam generator.
  • Plug in your device and test it.
