How to check if ref. 0020038572 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 0020038572. 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 that require diagnosis in the plate heat exchanger 0020038572

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 does not reach the temperature indicated on the panel.

  Cause: The heat exchanger does not transfer enough heat between the primary circuit and the domestic hot water circuit.

  Reduce the flow at the tap and see if it improves; if it heats well with low flow, the problem is in the heat exchanger.

• 02

  The hot water enters and exits, heats up and cools down irregularly.

  Cause: A partial blockage due to scale causes an unstable flow and the modulation becomes erratic.

  Check the cold water inlet filter, it often causes the same symptom and is cheaper to fix.

• 03

  The boiler frequently requests pressure and you need to refill the heating circuit.

  Cause: An internal leak between plates can mix water from the domestic hot water circuit with the heating circuit.

  Check if the mains water consumption has increased on the bill, it's another clue of a possible internal leak.

• 04

  The hot water comes out with a different color or taste than usual.

  Cause: Corrosion of the plates can affect the water circulating through the heat exchanger.

  Bleed several liters of water and check if the problem persists before replacing the part.

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.
