How to check if ref. 39818210 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 39818210. 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 39818210 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 needle remains fixed even when the circuit pressure changes.

  Cause: The internal mechanism is stuck and does not respond to pressure changes.

  Bleed a radiator and check if the overall pressure drops in the boiler; if the needle does not move, the fault is with the pressure gauge.

• 02

  It doesn't show pressure when refilling or bleeding the circuit, as if it were disconnected.

  Cause: The passage to the mechanism is blocked, usually due to scale buildup in the connection.

  Open the filling valve for a moment and check if you notice real pressure through another means before considering the pressure gauge as faulty.

• 03

  The pressure indicated does not match what it should be according to the installation.

  Cause: The internal spring loses calibration over time and the reading is no longer reliable even though the needle moves.

  Compare with the pressure displayed on the boiler, if available, before replacing the pressure gauge.

• 04

  The dial or the glass is broken or scratched, and the scale cannot be read properly.

  Cause: A blow during maintenance or assembly damages the plastic casing, which cannot withstand impacts.

  Check that the glass is intact on the outside; if it's just dirty, sometimes carefully cleaning it is enough.

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.
