How to check if ref. 8716771039 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 8716771039. If it is not visible, do not identify the part by 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 plate heat exchanger 8716771039 resolves.

The plate heat exchanger transfers heat to the domestic hot water. These are the typical symptoms and what to do:

Common symptoms and faults

• 01

  There is no domestic hot water, or it comes and goes while the tap is running.

  Cause: The plates of the heat exchanger accumulate lime inside, and the water flow becomes irregular.

  Measure the flow rate of domestic hot water with the tap fully open and check for limescale in the inlet filter before replacing the part.

• 02

  Water is leaking from the area where the heat exchanger is mounted.

  Cause: Over time, the plates or the joints between them degrade and start to leak.

  Dry the area thoroughly, start the boiler, and locate the exact point of the leak before assuming the part is responsible.

• 03

  The heating circuit loses pressure without any visible leaks.

  Cause: An internal leak in the heat exchanger allows water to pass from one circuit to another without being noticeable from the outside.

  Fill up to the operating pressure and see if it drops again in a couple of days without any water on the floor.

• 04

  A whistling sound is heard when the boiler is heating domestic hot water.

  Cause: The water is forced through channels narrowed by lime, and that produces the characteristic whistling sound.

  Check the water hardness and the condition of the inlet filter before replacing the heat exchanger.

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.
