3-Way Valve Actuator Motor Hermann Micra Condens 26
If you experience having hot water but no heating, or both circuits are mixing, a technical diagnosis must confirm if you need the Actuator Motor 3-Way Valve Hermann Micra Condens 26. This part is responsible for directing water between the heating circuit and the domestic hot water circuit. In case of a fault, you will notice that you cannot heat your home despite having hot water available. This actuator motor is compatible with several boilers from the Micra Condens range, including the Micra Condens 26, Micra Condens 26 V2, and Renova Micra Condens 26, among others. A technician must confirm through diagnosis if it needs to be replaced when there are faults in the switching of the circuits.

How to check if ref. H021004350 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 H021004350. 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 H021004350
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 does not switch between heating and domestic hot water.
Cause: The actuator does not receive the change command or the motor does not respond.
Activate the demand for domestic hot water and observe if the actuator moves or makes noise.
- 02
There is hot water but the radiators are not heating, or vice versa.
Cause: The valve is stuck in one of the positions and does not change.
Check if the problem occurs in both modes or only in one, to rule out that it is the demand from the control unit.
- 03
A noise or buzzing is heard in the actuator when trying to change.
Cause: The motor is forcing the rotation against a mechanism stuck due to limescale or dirt.
Check if the buzzing stops on its own or if the boiler needs to be turned off; a continuous buzzing indicates that the motor is straining.
- 04
The motor does not turn and the valve gets stuck in one position.
Cause: The motor winding is burnt or the internal gear is broken.
Check that power is reaching the actuator connector 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.
