Guide

How to check if the ref. 61400202 is the part for your boiler

What determines it is not the boiler model, but the reference printed on the part you already have installed.

  1. Find the reference printed on the installed part and check whether it matches the catalogue reference 61400202. 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 and faults that the expansion vessel 61400202 resolves.

The expansion vessel absorbs the expansion of water when heated. These are the typical symptoms and what to do:

Common symptoms and faults

  • 01

    The boiler shows an error or locks out due to low pressure more than once a month.

    Cause: The expansion vessel is not cushioning properly, which causes the system to lose pressure more frequently and reach the minimum that locks the boiler.

    Before changing the expansion vessel, check for any visible leaks in the radiators, bleed valves, or the filling valve.

  • 02

    There are banging noises in the pipes when turning on the hot water or starting the heating.

    Cause: The expansion vessel does not absorb pressure changes, which causes them to be transmitted as shocks throughout the system.

    Check that the thermostatic valves and the bleed valves are not blocked before blaming the vessel.

  • 03

    The pressure gauge jumps up suddenly as soon as the boiler starts and then slowly drops.

    Cause: This indicates that the expansion vessel does not have the correct pre-charge: all the initial expansion translates into pressure because there is no air to absorb it.

    Measure the pressure right at startup and again after ten minutes; a marked rise and fall indicates a problem with the expansion vessel.

  • 04

    The tank feels heavier than usual when holding or moving it.

    Cause: A glass of water due to a membrane rupture weighs more than one that contains air.

    If you can access the Schrader valve, press it with the circuit under no pressure: if water comes out, confirm the suspicion before purchasing.

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.
