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 boiler is stuck in one mode: it either heats radiators or provides hot water, and it does not switch from one to the other.

  Cause: The motor of the 3-way valve does not complete the rotation, so the diverter remains halfway between the two circuits.

  Before replacing the motor, check if it reaches the end of its travel: almost all have a visible position mark or arrow on the body.

• 02

  A buzzing or forced motor noise is heard when the boiler tries to switch circuits.

  Cause: The motor is powered and tries to turn, but the internal stem of the valve is seized, usually due to lime or dirt.

  Disassemble the motor and manually check if the shaft rotates freely; if it's difficult to move, the issue might be with the valve body, not the motor.

• 03

  The switching between heating and domestic hot water takes longer than usual or gets stuck halfway.

  Cause: It is a typical symptom of wear in the internal reduction gear of the motor, which loses strength over years of use.

  Time how long it takes to switch; if the time has increased week after week, it points to mechanical wear of the motor.

• 04

  The boiler gives a warning or locks up just when it should switch between heating and domestic hot water.

  Cause: The motor's limit switch does not confirm the position to the control unit, which for safety reasons locks the equipment.

  Check the motor's electrical connector and ensure that the wires are not loose, frayed, or corroded before considering it faulty.

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.
