Fugas de agua en una plancha Polti. Como cambiar el termostato

One of the most frequent breakdowns in Polti steam irons is that our ironing center throws water instead of steam through the iron. When we observe that a lot of water comes out due to the resistance of the iron, and that the sole does not heat enough,.com The fault is probably in the iron regulation thermostat of the appliance.

In electrotodo and electrotodo.com have more than 30 years of experience in repair of irons and all kinds of electrical appliances, so we are going to try to explain in the simplest way possible, how to carry out this repair.

In this tutorial we are going to address the replacement of the Polti plancha thermostat in a few simple steps to make the repair easy to perform. You can also follow these steps and see how a specialized technician performs them by visiting our tutorial on YouTube.

Time for a repair:

· approximately 30 minutes


· Intermedia

Tools needed:

  • Torx 10 screwdriver
  • Tamper-proof Torx 20 screwdriver (hollow)
  • Flat screwdriver (small)
  • Phillips screwdriver (medium)
  • · Pliers



  • · The first thing is remove the rear cover from the iron, with the Torx 10 screwdriver, remove the two rear screws.
  • · Remove the front screw of the casing (Torx 20 screwdriver), it is on the metal part of the plate.
  • · Remove (Torx 10) screws that hold the rear casings, under the connection strip.
  • · Separate cable connection strip (star screwdriver)
  • · Remove (Torx 10) screws that hold the rear casings, behind the connection strip.
  • · Using the flat screwdriver (small), remove the thermostat knob by prying it off.
  • · Pull on the front covers to separate the top and bottom of the iron.
  • · Remove thermostat shaft shim (a small black piece fitted to the thermostat shaft).
  • · Remove (star) the two screws (with their washers) that hold the metal support where the casings are mounted.
  • · Remove the fastening flange of the steam tube that is on the back of the iron and separate the tubes to be able to maneuver freely.
  • · Remove the cover/metal trim that goes over the resistance of the iron.

· The thermostat is only fixed to the resistance of the iron with a screw, it must be removed with the Phillips screwdriver.

· Remove (small plane) the cables that go from the thermostat to the connection strip. Be careful to photograph the position of the cables, because sometimes the manufacturer changes the color of their protections.

· Remove the faulty thermostat and replace it with the new replacement.


For the assembly we are going to follow the above steps in reverse order, (although with some changes) as follows:

  • · Screw (star) the new replacement thermostat to the axis of the resistance and check that it is aligned vertically with the iron and that we remove the thermostat cables from the rear part of the trim.
  • · Place the cover/metal trim that goes over the resistance of the iron. **Take care that the metal of the trim does not touch the rear terminals of the resistor!!.
  • · Place the thermostat cables in the same position on the rear connection strip. Screw in with the flathead screwdriver.
  • · Place the metal support where the casings are mounted and screw the two screws (with their washers) with the Phillips screwdriver.
  • · Place the upper casings, first the front part is placed and then we make the rear part fit into its corresponding place.
  • · Snap on the thermostat cover.
  • · Fix the screw of the front casing.
  • · Fix the two screws of the rear casing, which go under the connection strip.
  • · Connect the steam pipe that carries the steam from the boiler to the pipe of the iron and secure with the clamp. This metal clamp is attached to the tube of the iron (below). It will be necessary to use a pliers.
  • · Hold the strip on the axis that serves as a support and screw it with the Phillips screwdriver.
  • · Close the back of the plate with the two corresponding screws.
  • · Place the supplement on the axis of the thermostat of the iron and, on it, in the correct position, the regulation knob.

All that remains is to try the iron! Check, first of all, that when you plug in the device there are no shunt problems (they don't jump automatically). The next thing is to check that the iron heats up, this will prevent the water vapor from condensing when it reaches the metal of the resistance. Once the correct steam output has been verified and that the resistance of the iron heats up... We are done.

This repair, despite seeming complicated, due to the numerous steps to follow,.com Fairly simple, you just have to be organized and follow an established order.
