How to check if ref. 39820442 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 39820442. 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 39820442

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

  There is no domestic hot water but there is heating, or vice versa.

  Cause: The motor does not fully rotate the shutter, either due to wear or due to limescale buildup.

  Listen for a brief buzzing sound from the motor when requesting hot water; if you hear nothing, check the wiring and the fuse on the PCB before the gas valve.

• 02

  A metallic knock is heard when switching from heating to domestic hot water.

  Cause: The coupling between the motor and the shaft is loose or worn, causing knocks with each change.

  Check if the noise occurs consistently with each mode change; if it only happens sometimes, it may be air in the circuit and not the valve.

• 03

  There is a water leak in the area of the 3-way valve, sometimes only when the boiler is on.

  Cause: The body gaskets lose tightness due to cycles of heat and pressure.

  Dry the area, turn on the boiler, and observe if the dripping occurs when switching modes.

• 04

  The motor can be heard running, but the boiler still doesn't switch circuits properly.

  Cause: The internal shaft may be broken or uncoupled from the motor, even if it is functioning correctly.

  If the motor is running but the water mixture persists, it is a sign that the problem is internal mechanical and not electrical.

Ferroli fault codes that require diagnosis

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.
