How to check if ref. S5720600 is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

1. Find the reference printed on the installed part and check whether it matches the catalogue reference S5720600. If it is not visible, do not identify the part from its shape alone.
2. Check the full boiler model on its data plate and look for it in the model associations on this page.
3. Compare the connections and physical body with the original part before installation.
4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.

Symptoms that require diagnosis in the 3-way valve S5720600

The 3-way valve diverts water between heating and domestic hot water. These are the typical symptoms and what to do:

Common symptoms and faults

• 01

  The water comes out cold when I turn on the tap, even though the heating works without any issues.

  Cause: The motorized valve does not switch to the domestic hot water circuit, and the water continues to circulate only through the heating system.

  Check if you hear the actuator moving when you open the tap; if it remains silent, inspect the actuator before the boiler.

• 02

  Forced motor noise, like a buzzing that doesn't stop, near the three-way valve.

  Cause: The internal gear is worn out or the stem is seized, and the motor cannot complete the rotation.

  With the boiler turned off, try turning the stem by hand; if you feel resistance or it doesn't reach the ends, the problem is mechanical.

• 03

  The boiler remains fixed on heating or domestic hot water and does not change even if you request it.

  Cause: The actuator is stuck in one position and does not respond to the control unit's command.

  Check that the electrical connector of the actuator is properly inserted and free of corrosion before replacing it.

• 04

  Domestic hot water and heating are heating simultaneously, but neither reaches the desired temperature.

  Cause: The valve does not fully close either of the two circuits, and the water is distributed between both.

  Check if the actuator reaches a clear stop in both positions or if it stops halfway.

These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
