3 Bar Safety Valve 1 Ferroli Metallic Domicompact F30 Ref. 39809740

Ferroli boilers from the Domicompact range use the 3 Bar Safety Valve 1 Ferroli Metal Domicompact F30, which is responsible for releasing water when the circuit pressure exceeds 3 bar. If this valve fails, you will notice continuous dripping or that it does not discharge properly when needed. It is compatible with several models, such as Domina F24, Domina F30, Domicompact F24, Domicompact F30, among others. A technician must confirm through diagnosis whether it needs to be replaced when it shows signs of malfunction.

Guide

How to check if the part number 39809740 is the correct one 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 39809740. 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 safety valve 39809740

The safety valve releases pressure when the circuit exceeds its setting. These are the typical symptoms and what to do:

Common symptoms and faults

  • 01

    The valve is constantly leaking water from the drain tube, even when the boiler is cold.

    Cause: The internal seat does not seal completely, either due to wear or because a particle is preventing full closure.

    Measure the pressure on the manometer with the boiler cold: if it exceeds approximately 1.5 bar, bleed the circuit before replacing the gas valve, as the dripping may be due to excess pressure and not the part.

  • 02

    After bleeding and lowering the pressure, the gas valve still won't stop dripping.

    Cause: There is dirt or limescale lodged in the seat, preventing it from closing cleanly after the shot.

    Actuate the bleed lever of the valve several times to remove dirt before considering it faulty.

  • 03

    There is a water leak right at the fitting where the gas valve is screwed in, not in the body.

    Cause: The fitting of this type of gas valve has a gasket or thread that degrades over time and with the expansions of the circuit.

    Tighten the fitting carefully and check if the leak is coming from the connection gasket before assuming that the valve is broken; sometimes it is enough to just replace the gasket.

  • 04

    The valve does not expel water when the boiler exceeds pressure.

    Cause: The internal mechanism has become jammed, which is common if it hasn't been triggered for a long time.

    Lift the test lever manually, if it has one, and check that it moves normally and releases some water; if it is stuck, check that it is not painted or covered on the outside.

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.
