Baxi Eco 20 FP PCB Control Ref. JJJ005645600
Baxi Eco FP features the Baxi Eco 20 FP Control PCB, which is responsible for managing the ignition, burner modulation, pump, and safety features of the boiler. When this part fails, it is possible that the boiler may not start, become locked, or exhibit erratic behavior. This board is compatible with models such as the Eco 20 FP, among others in the Baxi Eco FP range. A technician should confirm through diagnosis whether it needs to be replaced when these symptoms are noticed to avoid further issues.

How to check if the reference JJJ005645600 is the part for your boiler.
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference JJJ005645600. 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 that require diagnosis on the PCB JJJ005645600
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 turn on: there is no display, lights, or noise from the pumps when connected.
Cause: The PCB does not supply power to the other components even though it receives current.
Check the fuse on the PCB and verify that the mains supply is correct before replacing it.
- 02
The panel lights up but nothing happens when requesting heating or domestic hot water.
Cause: The PCB receives the command, but does not activate the burner ignition.
Confirm that the thermostat or the domestic hot water tap is actually sending the demand signal before replacing the PCB.
- 03
Error codes appear that change for no apparent reason, or the boiler turns off and on by itself.
Cause: A fault in the control electronics causes unstable readings from the connected sensors.
Note the code and when it appears: sometimes it indicates a specific sensor, not the entire PCB.
- 04
The boiler turns off a few seconds after starting, repeatedly.
Cause: A faulty relay contact on the PCB interrupts the power supply to a component necessary for maintaining ignition.
Check that the connectors on the PCB are properly tightened and free of oxidation before replacing it.
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.
