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.
- 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.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- 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
Hot water comes out of the tap but the radiators do not heat up, or vice versa.
Cause: The motor does not move the rod to the correct circuit and the boiler only serves one of the two.
Turn on a hot water tap and listen to see if the actuator clicks or turns; if it doesn't move, suspect the motor before the valve.
- 02
A continuous buzzing or a repeated clicking sound is heard near the three-way valve.
Cause: The motor tries to turn against a worn gear or a stem seized by lime and does not complete the cycle.
With the boiler off, try to manually move the valve stem; if it's stiff or doesn't reach the stops, confirm the fault before ordering the actuator.
- 03
The boiler alternates between heating and domestic hot water without stabilizing in either.
Cause: The actuator does not reach the end of travel in any position, and the valve remains halfway, mixing both circuits.
Check that the actuator is properly fitted into the valve body and that the electrical connector is not loose.
- 04
The boiler locks out or shows a warning related to the three-way valve when requesting domestic hot water.
Cause: The control unit does not receive confirmation that the motor has changed position and shuts down for safety.
Check the wiring of the actuator and make sure there is no moisture or corrosion in the connector before replacing it.
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.
