Guide

How to check if ref. 65117952 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 65117952. 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 hydraulic group 65117952

The hydraulic group includes the valve, the by-pass, and the water connections. These are the typical symptoms and what to do:

Common symptoms and faults

  • 01

    The boiler needs pressure recharging more frequently than usual.

    Cause: The left hydraulic group has a gasket or fitting that leaks water gradually, sometimes without a noticeable puddle.

    Check the fittings and the body of the hydraulic group on the left side with dry paper.

  • 02

    Moisture or dripping appears on the lower left side of the boiler.

    Cause: The body of the hydraulic group is cracked or an internal seal has lost its tightness.

    Check the leak point with the boiler cold and again after a heating cycle.

  • 03

    The domestic hot water comes out with low pressure or intermittently.

    Cause: The water passage of the hydraulic group is partially blocked, usually by limescale.

    Compare the flow rate at a faucet close to the boiler with one that is farther away.

  • 04

    There is no domestic hot water, but the heating works normally.

    Cause: The domestic hot water circuit of the hydraulic group is blocked, or the flow sensor does not detect water consumption.

    Open the hot water tap slowly and check if the boiler responds.

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.
