PCB Cointra Supra Compact SPC 21 EI
The Cointra Supra Compact boilers use the SPC 21 EI control PCB, which manages the ignition, burner modulation, pump, and safety features of the boiler. If this part fails, you will notice that the boiler does not start, locks out, or behaves erratically. This PCB is compatible with the SPC 21 EI model, among other boilers in the Supra Compact range. It is recommended to replace the PCB when you experience these operational issues.

How to check if ref. 9158750 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.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 9158750. 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 PCB 9158750 resolves.
The PCB controls the ignition, modulation, and safety features of the boiler. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler does not ignite and the ignition indicator does not even blink.
Cause: If the PCB does not receive power or its start-up stage is damaged, it cannot initiate the ignition sequence.
Check that the transformer and the fuses in the installation are fine before declaring the PCB defective.
- 02
The flame ignites, but the boiler shuts off after a few seconds, always the same.
Cause: The PCB cuts off the gas if it does not receive the signal that the flame has stabilized in time, even if the problem is with the sensor and not with it.
Check the cleanliness and connection of the flame detection electrode before replacing the PCB: it is a much more common fault.
- 03
Did you move the boiler or do any work nearby, and since then it has been malfunctioning?
Cause: Impacts, humidity, or construction dust can damage the contacts and components of a PCB that was functioning well until then.
Open the cover and visually check for dust, moisture, or any loose connectors before replacing the PCB.
- 04
The boiler works but loses the time or the settings every few days.
Cause: That type of memory depends on the PCB; if it loses the saved data, it usually indicates a fault in the backup battery or the memory circuit itself.
First, check if your model has a separate backup battery and if it is depleted, before considering replacing the entire PCB.
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.
