How to check if ref. 122153240 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 122153240. 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 hydraulic group 122153240 solves.

The hydraulic group includes the valve, the by-pass, and the water connections. These are the typical symptoms and what to do:

Common symptoms and faults

• 01

  A very fine water leak appears, almost like sweating, on the surface of the aluminum block.

  Cause: It's a typical fault of cast aluminum parts: casting micropores that over the years and under pressure end up seeping.

  Dry the surface thoroughly, start the boiler, and locate the exact point where the moisture is coming from before replacing the entire block.

• 02

  There are white or greenish stains around the connections of the hydroblock, although no water is visibly dripping.

  Cause: It is aluminum oxidation due to prolonged contact with moisture, indicating a slow leak that has been active for some time.

  Clean the residue and check if it reappears after a couple of days of normal use.

• 03

  The leak is coming right at the joint where the pump or the three-way valve is screwed into the block, not in the aluminum body.

  Cause: Those joints rely on seals that degrade before the metal block itself.

  First, change the gasket of that specific joint and check if the leak disappears before replacing the hydroblock.

• 04

  Tightening the securing screws to try to stop a leak does not improve it or even makes it worse.

  Cause: If the problem is an internal casting pore, tightening won't help because the leak doesn't come from a joint but from the metal itself.

  Mark the exact point of the leak with a marker and confirm that it does not coincide with any joint or fitting before considering the block defective.

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.
