How to check if ref. 05236600 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 05236600. 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 and faults that the expansion vessel 05236600 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

  You have to fill the heating circuit more often than usual.

  Cause: The vessel has lost air or the membrane is damaged, which prevents maintaining the pressure in the circuit.

  Check for visible leaks in the bleed valves, radiators, or safety group; if there are no leaks and it continues to lose pressure, the problem may be the expansion vessel.

• 02

  The safety valve intermittently discharges water when the heating has been on for a while.

  Cause: Without air in the expansion vessel, the hot water has no space to expand and spills out through the safety valve.

  Check the cold fill pressure: if the circuit is heavily loaded, the dripping may be due to excess pressure and not from the expansion vessel.

• 03

  The glass sounds full of water when struck with the hand, without air resonance.

  Cause: When losing air, the tank fills with water and no longer has the gas chamber that makes it sound hollow.

  Test the cold system and without pressure, tapping in several points of the tank, not just in one.

• 04

  The pressure gauge rises quickly when starting the heating.

  Cause: An exhausted vessel cannot absorb the expansion of water, which causes an increase in pressure in the circuit.

  Note the cold pressure and compare it with that of a few minutes of operation; a rapid and repeated increase indicates a diaphragm expansion vessel without charge.

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.
