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 motor of the valve does not turn, it remains stationary, and the boiler does not switch from heating to domestic hot water.

  Cause: The winding or the internal gear of the actuator does not have the strength to move the valve.

  With the boiler requesting domestic hot water, touch the motor body: if it doesn't vibrate or make noise, try the manual mode of the actuator if the boiler allows it.

• 02

  You notice a sharp click in the valve right when it should switch modes.

  Cause: The motor's reduction gear is slipping or a tooth has broken, preventing it from transmitting rotation to the shaft.

  With the boiler unplugged, manually turn the actuator shaft and check if it moves the valve without abnormal resistance.

• 03

  Depending on the position the valve gets stuck in, you have heating but no domestic hot water, or vice versa, and there's no way for it to change.

  Cause: The actuator has stopped halfway, and the valve is stuck between the two positions.

  Before replacing the motor, disassemble it and confirm that the valve stem moves freely without it in place.

• 04

  The boiler attempts to switch but immediately returns to the same mode.

  Cause: The motor receives the command but does not complete the stroke, so the control unit does not detect the correct position.

  Check the wiring and connector of the actuator: a loose contact can simulate a motor fault.

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.
