How to check if the part number 125089600 is the correct 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 125089600. 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 gas valve 125089600 resolves.
The gas valve regulates and modulates the gas flow to the burner. These are the typical symptoms and what to do:
Fault codes Baxi that this part resolves
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 134 | Gas valve blocked. | The gas valve is stuck or its coil is not operating, preventing opening/modulation and ignition. Check the control signal and voltage at the valve, coil resistance, and gas supply pressure during demand. |
| 15 | Gas valve control error. | Fault in the valve control (loose connector, damaged wiring, or open coil), so the PCB cannot actuate the valve. Check continuity from the PCB to the valve connector and the presence of control voltage during the ignition attempt. |
| 09 | Gas valve connection error. | The boiler detects a loss of communication/electrical connection with the valve (loose connector, damaged harness). Check the fixation of connectors, continuity of cables between the PCB and valve, and absence of shorts/opens. |
| H.01 .00 | Temporary communication failure between the gas valve and the PCB. | Intermittencies in the valve (connector/coil) cause temporary loss of communication. Check terminals and ground, clean/adjust terminals, and check control/modulation signal to the valve during start-up. |
| E.02 .17 | Permanent communication failure between the gas valve and the boiler PCB. | Fault in the valve or its harness causes permanent loss of communication. Check continuity of the wiring, power supply/output of the PCB, and coil resistance; if there is a control board and the valve does not respond, replace the valve. |
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.
