How to check if the reference 053471 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 053471. 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 053471 resolves
The gas valve regulates and modulates the gas flow to the burner. These are the typical symptoms and what to do:
Fault codes from Vaillant that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F.61 | Fault: gas valve operation. | The PCB cannot correctly operate the gas valve (coils in short circuit/ground or without signal), preventing its opening/modulation. Check the continuity of coils, wiring, and control signal to the valve during the ignition attempt. |
| F.62 | Gas valve disconnection delay. | The gas valve does not close in time or loses tightness, resulting in residual flow and/or delayed flame signal. Check the tightness of the assembly and closing times by measuring ionisation and pressure at the ports before/after the valve when stopping the burner. |
| F.28 | Start-up fault: ignition failed. | If the gas valve is faulty/stuck or improperly actuated, it does not supply gas to the burner despite the presence of a spark, resulting in no flame. Check the control voltage to the valve during the ignition attempt and the outlet pressure at the test point. |
| F.29 | The flame goes out during operation and the ignition retry fails. | A faulty or improperly adjusted gas valve can cause unstable flow/pressure and flame extinction under load. Check valve modulation, dynamic pressure in service, and adjustment with a combustion analyser. |
| F.27 | Safety shutdown: flame simulation. | Gas leaks or defective closure of the magnetic gas valve may allow gas to pass when it should be closed, resulting in an improper 'flame' detection. Check the valve's tightness and ensure that the ionisation signal drops to 0 when the gas is shut off. |
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.
