Water leaks in a Polti iron. How to change the thermostat

One of the most frequent malfunctions in Polti steam irons is that our ironing center is throwing water instead of steam through the iron. When you notice that a lot of water comes out of the iron's heating element, and that the sole does not heat up enough, it is likely that the fault lies in the iron's thermostat control of the appliance.

- Remove the faulty thermostat and replace it with the new part.

ASSEMBLY.

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

  • - Screw (star) the new replacement thermostat to the resistor shaft and check that it is aligned on the vertical of the plate and that we pull the thermostat wires through the back of the trim.
  • - Place the metal cover/flap over the heating element of the griddle. **Be careful that the metal trim does not touch the rear terminals of the resistor!!!
  • - Place the thermostat wires in the same position on the rear terminal strip. Screw them in with the flat screwdriver.
  • - Place the metal bracket where the housings are mounted and screw the two screws (with their washers) with the Phillips screwdriver.
  • [if !supportLists]-->- Place the metal bracket where the housings are mounted and screw the two screws (with their washers) with the Phillips screwdriver.
  • - Place the upper housings, first place the front part and then fit the rear part in its corresponding place.
  • - Fit, snap on the thermostat cover.
  • [if !supportLists]-->- Fit, snap on the thermostat cover.
  • - Fasten the front housing screw.
  • - Fasten the two screws on the rear housing,which go under the terminal strip.
  • [if !supportLists]-->- Fasten the two screws on the rear housing,which go under the terminal strip.
  • - Connect the steam pipe that carries the steam from the boiler to the iron pipe and secure with the clamp. This metal clamp is placed on the iron tube (below). It will be necessary to use a pair of pliers.
  • - Fasten the clamp on the shaft that serves as a support and screw it with the Phillips screwdriver.
  • [if !supportLists]-->- Fasten the clamp on the shaft 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 thermostat shaft of the plate and, on it, in the correct position, the regulation knob.

All that remains now is to test the iron! First of all, check that when plugging in the appliance there are no problems with shunts (no automatic jumping). The next thing is to check that the iron heats up, this will ensure that the water vapor does not condense on reaching the metal of the heating element. Once you have checked that the steam is coming out correctly and that the heating element of the iron is heating up...

We are done.

This repair, despite seeming complicated, by the numerous steps to follow, is fairly simple, just be neat and follow an established order.
