How to check if the part N40G000M6 is the one 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 N40G000M6. 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 N40G000M6 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 circuit needs to be filled more frequently, almost every week, even though no leaks are visible.

  Cause: The air precharge of the expansion vessel has been gradually escaping, and it is cushioning less and less, so the system "sucks" in more water to compensate.

  Check the fittings, bleed valves, and the filling valve for any small leak that might be concealing the real problem with the expansion vessel.

• 02

  The needle of the pressure gauge moves a lot as soon as the heating is turned on.

  Cause: Without the air cushion in the vessel, the expansion of the water directly translates into visible pressure on the manometer.

  Compare the cold pressure and a few minutes after starting; a large and sudden difference indicates the expansion vessel.

• 03

  There is noticeable moisture at the base of the boiler or near the expansion vessel without a clear leak in the pipes.

  Cause: If the diaphragm of the vessel is broken, it may start to leak water from the housing itself or from the air valve.

  Dry the area well and check in cold if humidity reappears right next to the tank before looking at other joints.

• 04

  The boiler is locking out due to low pressure more often than usual in a short period of time.

  Cause: The expansion vessel no longer compensates for pressure variations, and the system reaches the minimum threshold that shuts off the boiler for safety reasons.

  Before replacing the expansion vessel, check for any visible leaks and ensure that the filling valve closes properly after refilling.

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.
