How to check if ref. 8716771039 is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

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 that require diagnosis in the plate heat exchanger 8716771039

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

  The domestic hot water is becoming less efficient, taking longer to heat up or staying lukewarm.

  Cause: The plates of the heat exchanger accumulate lime inside and transmit less heat to the domestic hot water.

  First, check if the water in the area is hard and if the boiler has never been descaled.

• 02

  Water is dripping or there is moisture in the lower area of the boiler, near the heat exchanger.

  Cause: The seals or the welding between plates have given way, and water is leaking through there.

  Locate the exact point of the leak with the boiler on before ordering the part; it could be a nearby fitting and not the heat exchanger.

• 03

  The heating circuit gradually loses pressure without any visible puddle.

  Cause: An internal leak in the heat exchanger can allow water to pass from one circuit to another without leaking outside.

  Watch if the pressure rises right when you open the hot water tap, it's a sign that the heat exchanger is mixing the two circuits.

• 04

  There is a noise like boiling water or sizzling when it demands domestic hot water.

  Cause: The lime scale deposited on the plates overheats the water at specific points and causes that localized boiling.

  Bleed the circuit and check the condition of the water before considering the part lost; sometimes a descaling 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.
