3-Way Valve Actuator Motor Saunier Duval Isofast C35 E1

3-Way Valve Actuator Motor Saunier Duval Isofast C35 E1

The 3-way valve of the Saunier Duval Isofast C35 E1 actuator switches the water between the heating circuit and the domestic hot water circuit. When it fails, you may notice that there is hot water but no heating, or that both circuits are mixing. This component is compatible with several models, such as the C 28 E, F 28 E, C 35 E, and F 35 E, among others in the Isofast range. A technician must confirm through diagnosis whether it needs to be replaced if you experience these issues to restore the proper functioning of your boiler.

Guide

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.
Diagnosis and fault codes

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 works in one mode and does not switch to the other service.

    Cause: The motor does not move the valve to the end of its travel in the requested circuit.

    Force the service change a couple of times and see if it moves on any attempt.

  • 02

    The motor tries to turn and makes a short buzzing sound, but the valve does not move.

    Cause: The coupling between the motor and the valve shaft has failed, or the gear is worn out.

    Check if the outer shaft of the motor is turning, even if the valve does not change; that indicates a problem with the coupling, not with the motor.

  • 03

    When requesting hot water with the heating on, it takes a long time to come out hot or it doesn't heat well.

    Cause: The valve does not completely close the heating flow when it should prioritize domestic hot water.

    Turn off the heating and repeat the domestic hot water test alone before concluding that the motor is faulty.

  • 04

    A warning or error related to the three-way valve appears, and the boiler cuts off the service.

    Cause: The control board does not receive confirmation of the position change in time and locks for safety.

    Reset the boiler and note if the fault always repeats at the same point in the cycle before ordering the spare part.

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.
