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 only provides hot water or heating, without distributing between the two.

  Cause: The valve has become stuck in one of the positions and does not change.

  Manually request a mode change and observe whether the motor attempts to move or does not react.

• 02

  The display shows a valve motor or limit switch error.

  Cause: The control board does not receive the signal that the motor has completed its travel on time.

  Check if the fault always occurs at the same point in the cycle; if so, point to the gas valve.

• 03

  The motor does not turn or gets stuck halfway when switching circuits.

  Cause: The internal mechanism of the actuator is jammed or the gear has lost traction.

  Check if you feel resistance when turning the shaft by hand with the boiler off; if it is difficult, it may be due to scale or dirt in the gas valve.

• 04

  The heating takes longer than usual to warm up after requesting hot water.

  Cause: The valve does not fully return to the heating circuit after responding to the domestic hot water request.

  Time how long it takes to heat up after closing the tap; if the delay is always large and consistent, check the entire path of the gas valve.

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.
