How to check if the part number 125036000 is the one for your boiler.
What determines it is not the boiler model, but the reference printed on the part you already have installed.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 125036000. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms and faults that the heat exchanger 125036000 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
The hot water comes out with a good flow but does not reach the temperature it used to achieve.
Cause: The secondary plate heat exchanger loses efficiency due to the accumulation of scale between the plates, which reduces the contact surface.
Increase the set temperature of the domestic hot water on the panel and check if it improves; if it doesn't change, the problem is with the PCBs.
- 02
The boiler takes longer to start the hot water mode, as if it struggles to notice that the tap has been opened.
Cause: A reduced flow due to obstructed plates may be below the minimum required by the flow sensor to activate the burner.
Open the hot water tap to the maximum and observe if the boiler ignites immediately; if it takes time or fails, measure the actual flow rate that comes out.
- 03
Water is leaking from the bottom of the boiler only when the hot water is used, not with the heating.
Cause: Welded plates can crack due to the fatigue from temperature changes, allowing water to leak at the joint with the circuit.
Locate if the dripping appears just below the secondary heat exchanger and if it coincides with the use of domestic hot water before considering the part as responsible.
- 04
The hot water comes out in bursts, alternating between hot and lukewarm, for no apparent reason.
Cause: A partially obstructed passage causes the flow rate to vary, affecting the outlet temperature, as the boiler modulates according to that flow rate.
Check if the fluctuations coincide with the simultaneous use of another tap in the house before ruling out a network pressure issue.
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.
