Guide

How to check if it is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

Please confirm: Look for 1271002190 on the PCB: it usually says it is screen printed on the circuit or on a side sticker.
Also compare the circuit E961077E and those marked ECOBIT FF, 9555516800C, U3 961079R, and U4 961080A-3.
Compare the number and position of the relays and connectors: the same reference has different versions.
Do not confuse it with 122123620 (Neobit 24/24 without F) or with 125566966 (Neobit S 24/24 F).
if they match, call us at 911 17 77 77 with the model of your boiler.

Diagnosis and fault codes

Symptoms that require diagnosis on the PCB

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 or respond to any commands from the front panel.
Cause: To confirm: It is associated with this PCB.
02
Continuous resets in heating or domestic hot water.
Cause: Also relate it to this PCB; have a technician confirm it.
03
Strange clicks or stuck relays in the circuit.
Cause: Stuck relay signal.
04
The boiler does not ignite and locks with pilots 60, 70, and 90 lit.
Cause: Lack of gas or spark in the ignition.
Check that gas is reaching and that the valve is open. If it happens again, have a technician check the ignition and the PCB.
05
The boiler does not ignite and several temperature LEDs remain lit along with the fault LED (60-70-90 or 40-80-90).
Cause: There is no gas reaching the boiler or there is no ignition spark.
Check that the gas shut-off valve is open. If it still doesn't ignite, have a technician check it.
06
The boiler is locked with LEDs 50 and 90 lit along with the anomaly LED.
Cause: Faulty heating sensor or damaged sensor cable.
Have a technician check it: the sensor and its cable are inside the boiler.

Fault codes Baxi Roca that require diagnosis

Code	Fault	Technical checks
60-70-90	Ignition lock: the burner does not ignite due to lack of gas or spark.	Check that gas is arriving and that the valve is open. If it repeats, have a technician check the ignition; point to the PCB if the gas and spark are fine.
40-80-90	Gas shortage with the boiler in operation, or total or partial electrical failure. LEDs 40, 80, and 90 light up along with the anomaly LED.	Check that gas is arriving (shut-off valve open). If it repeats, have a technician check it: it may be on the PCB.
60-90	The flame relay is faulty or turned off. LEDs 60 and 90 light up along with the anomaly LED.	If the flame does not stay on even though gas is reaching it, have a technician check it: it points to the PCB.
50-90	Heating sensor faulty or with damaged cable. LEDs 50 and 90 light up along with the fault LED.	Have a technician check it: the sensor and its cable are inside the boiler. It points to the PCB, which is the one that reads the sensor.
40-60-90	Fault in the safety circuit. LEDs 40, 60, and 90 light up along with the anomaly LED.	Reset the boiler once. If it blocks again, have a technician check it: it points to the PCB.
70-90	Safety fuse open. LEDs 70 and 90 light up along with the fault LED.	The fuse should be replaced by a technician, who must also investigate the cause, as it may happen again.
40-70-90	Gas solenoid valve power failure. LEDs 40, 70, and 90 light up along with the fault LED.	Reset and check that gas is reaching. If it repeats, have a technician check it: it points to the PCB or the power supply to the gas valves.
50-70-90	The safety relay does not close after the heat demand. LEDs 50, 70, and 90 light up along with the fault LED.	Have a technician check it: it points to the PCB, which controls the safety relay.
40-50-70-90	The burner shuts off because the ignition time is too short. LEDs 40, 50, 70, and 90 light up along with the anomaly LED.	Reset once. If it repeats, have a technician check it: it points to the PCB, which manages the timing.
40-60-70-90	The burner shuts off because the ignition time is too long. LEDs 40, 60, 70, and 90 light up along with the anomaly LED.	Reset once. If it repeats, have a technician check it: it points to the PCB, which manages the timing.

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.

Frequently Asked Questions

Frequently asked questions about the PCB (control board)

How do I identify the PCB 1271002190?

Look for 1271002190 printed on the PCB; it usually appears silk-screened on the circuit or on a side sticker. In this unit, E961077E is the circuit code and ECOBIT FF is the marked name. It also has 9555516800C, U3 961079R, U4 961080A-3, and 0612; without additional confirmation read them for explanations.

Is it compatible with my Baxi Roca Neobit 24/24 F?

The compatibility of this variant is pending confirmation. Registered: for the Baxi Roca Neobit 24/24 F, and it also applies to that external boiler. Nevertheless, compare the code 1271002190 of your PCB with the one in the photo.

Does it fit in other Baxi Roca boilers besides the Neobit 24/24 F?

The compatibility of this variant is pending confirmation. This also applies to Neobit 24/24 F R, Neobit Plus 24/24 F and F R, Ecobit 24/24 F and F R, Ecobit Compact 24/24 F, Sara 24/24 F, and Nora 24/24 F. It is a single one and not confirmed; it also provides another PCB (125128870) for the Neobit Plus 24/24 F and another one (122123640) for the Nora 24/24 F. Compare the code or send us a photo of your PCB from Contact.

Is 1271002190 the same as 122123680?

The compatibility of this variant is pending confirmation. It is not confirmed. (and the blog) gives the Roca code 122123680 for the PCB of the Neobit 24/24 F, but none links it to 1271002190. We do not consider it equivalent: compare code and photos.

What is the difference between the PCBs 122123620 and 125566966?

To confirm: 122123620 is for the Neobit 24/24 and 125566966 is for the Neobit S 24/24 F, and neither is interchangeable with 1271002190. It states that 125566966 is replaced by 125568548. The blog also lists 125568739 (Honeywell, Victoria 24 / Neobit 24).

What should be checked when installing it and who is recommended to install it?

Compare relays and connectors: the same reference has different versions. Take a photo of the six-position DIP before disassembling and check the 2 A and 3.15 A fuses. It is recommended that a qualified technician install it to avoid short circuits.

What symptoms point to this PCB?

To confirm: what does the 1271002190 sell? It refers to a boiler that does not ignite or does not respond to the front panel, continuous resets, clicks or stuck relays, and burnt or oxidized tracks. It is not a substitute for a technician's diagnosis.

How to identify this PCB?

Compare the silkscreen, the distribution of the connectors, and the exact variant of the circuit with the photographs.
