How to check if ref. 8718224344 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 8718224344. 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 pressure gauge 8718224344 resolves.

The manometer shows the pressure of the boiler circuit. These are the typical symptoms and what to do:

Common symptoms and faults

• 01

  The pressure gauge reads zero or the needle doesn't move, even though you know the system is pressurized.

  Cause: The internal mechanism of the pressure gauge has jammed or lost connection with the circuit and does not reflect the actual pressure.

  Bleed a radiator and refill it with the filling key; if the needle does not react at any moment, the pressure gauge is faulty.

• 02

  The needle stays outside the green range and doesn't return no matter how much you refill the circuit.

  Cause: A misalignment of the internal mechanism causes the needle to display incorrectly even though the actual pressure is within range.

  If you have another manometer or one from a similar boiler on hand, compare readings before discarding the manometer you have installed.

• 03

  The glass or the sphere is broken and the color scale cannot be read.

  Cause: A blow or the aging of the plastic has damaged the casing without affecting the rest of the circuit.

  Check at the same time that the connection fitting is not leaking; if only the reading fails, the change is only for the pressure gauge.

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.
