Guide

How to check if the ref. 6319639A 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 6319639A. 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 filling valve 6319639A

The filling valve allows water to refill the heating circuit. These are the typical symptoms and what to do:

Common symptoms and faults

  • 01

    It is leaking from the filling valve.

    Cause: The gasket has lost elasticity and does not seal properly.

    Locate whether the drip is coming from the inlet fitting, the outlet fitting, or the body itself before requesting the spare part.

  • 02

    It doesn't close properly and water keeps coming in.

    Cause: The internal seat is damaged and does not stop the flow even when the lever is fully open.

    Close the main valve of the installation and check if the pressure gauge continues to rise; this way you can confirm that the flow is coming from this valve.

  • 03

    The handle turns but does not stop the water flow.

    Cause: The stem has become uncoupled from the shutter and the handle turns without acting on the closure.

    Note if there is a clear closing stop at any point of the turn; if the handle turns freely without resistance, the stem is broken.

  • 04

    The handle is stuck.

    Cause: Limescale or debris has blocked the internal mechanism due to lack of use.

    This symptom may be related to the part, but it does not confirm that it is faulty. A technician must check the equipment and its inspection according to the manual before deciding on a repair or replacement.

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.
