Glowworm PCB Interface Ref. 0020027897
Glowworm interface PCB with catalog reference 0020027897. It is an electronic component of the user interface, not a heat exchanger. Before purchasing, confirm reference, revision, and connections with the installed part. A display or control fault requires diagnosis; this PCB does not identify itself as the cause.

How to check if the ref. 0020027897 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 0020027897. 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 0020027897
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 respond to the controls or the thermostat, as if it were completely dead.
Cause: This interface PCB manages the communication between the control and the control board; if it fails, the boiler stops responding to commands.
Before replacing it, check that the boiler has electrical power and that the fuse on the main PCB is not blown.
- 02
The display or the indicator lights are flickering strangely, or they remain off even though the boiler is powered.
Cause: A fault in this interface PCB directly affects how information is displayed to the user, even though the control unit continues to operate.
Disconnect and reconnect the interface connector to rule out a poor connection before declaring the part faulty.
- 03
The boiler is displaying a fault code related to communication, or it does not recognize the remote control.
Cause: If this interface does not transmit the signal well between the remote control and the main PCB, the control unit interprets that there is a communication fault.
Check the wiring and connectors between the interface and the PCB: a loose connection gives the same fault as a damaged part.
- 04
The buttons on the boiler do nothing when pressed, although the rest of the equipment seems to turn on normally.
Cause: This PCB collects the pulses and translates them into commands to the control unit; if it fails, the buttons stop having any effect.
Check if the fault also appears when using the room thermostat, if you have one: it will tell you if the problem is only with this interface or with the boiler in general.
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.
