How to check if the reference 0020053968 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 0020053968. 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 0020053968 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.26 | Stepper motor current of the gas valve not plausible. | The stepper motor/solenoids of the valve are disconnected or faulty, preventing correct modulation/opening. Check continuity and resistance of coils, connector, and control signal; verify steps/offset of the valve in the equipment diagnostics. |
| F.27 | Safety shutdown: flame simulation. | The gas valve does not close tightly and allows gas to pass (solenoid with a leak), generating a flame signal when it should be off. Check the valve's tightness with a leak test and ensure ionisation disappears after closing. |
| F.28 | Start-up fault: ignition not achieved. | If the gas valve does not open or is improperly adjusted, gas does not reach the burner and the unit does not ignite. Check excitation/controls to the valve during the ignition attempt and pressures before/after the valve. |
| F.61 | Fault in the regulation/operation of the gas valve. | Short to ground/short circuit in the harness to the valve or defective solenoids/valves prevent their operation. Check insulation/continuity of coils and power supply from the PCB to the valve. |
| F.62 | Gas valve disconnection delay. | The valve gets stuck or leaks and does not close in time, leaving a flame signal after shutdown. Verify that ionisation ceases when cutting off and perform a tightness/leak test on 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.
