Guide

How to check if the reference 00201861 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 00201861. 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.
Diagnosis and fault codes

Symptoms that require diagnosis in the plate heat exchanger 00201861

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

    Little hot water is coming out, or the temperature fluctuates for no reason at the faucet.

    Cause: The plates get clogged with limescale and reduce the flow rate that the heat exchanger can heat.

    Check the flow of the domestic hot water tap at maximum: if it is low compared to the cold water, suspect obstruction before replacing the part.

  • 02

    The hot tap water comes out cloudy or with a strange smell.

    Cause: A crack between the plates can allow water to pass from one circuit to another.

    Check if you notice any color or smell of product from the heating circuit in the domestic hot water, and if you have to refill the pressure more often than usual.

  • 03

    The boiler heats the radiators well, but the domestic hot water does not reach the set temperature.

    Cause: When the plates are embedded, the heat exchange to the domestic hot water circuit loses efficiency.

    Increase the setpoint temperature of the domestic hot water and check if there is any improvement: a partial improvement suggests scaling in 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.
