Vaillant Turbo Tec VMW ES 282 2 5 SIT Gas Valve Ref. 053462
The Vaillant Turbo Tec VMW ES 282 2 5 SIT gas valve regulates and allows the flow of gas to the burner according to the commands from the control board. If it has faults, you will notice that the boiler does not ignite, there may be flame lockouts, or the gas modulation is not adequate. This valve is compatible with models such as VMW 240-3, VMW 242-5, among others from the TurboTec and AtmoTec ranges. A technician must confirm through diagnosis whether it needs to be replaced when errors such as F.26, F.61, or F.28 are detected, which indicate problems with the gas valve.

How to check if ref. 053462 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 053462. 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 in the gas valve 053462
The gas valve regulates and modulates the gas flow to the burner. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler makes a loud bang when starting, like a small explosion, instead of igniting the flame smoothly.
Cause: The gas valve allows too much gas to flow suddenly when starting, instead of opening gradually.
Check that the burner and the combustion chamber are free of soot and accumulated dirt; this can also cause rough ignitions.
- 02
The boiler does not respond when requesting hot water or heating, although the control seems to be working fine.
Cause: If the gas valve does not open, there is no flame even though the rest of the system is functioning correctly.
Confirm that the thermostat or the control is actually requesting temperature and that it is not a programming issue before checking the gas valve.
- 03
In heating, everything works well, but when requesting hot water, the flame is weak or unstable.
Cause: The valve may fail in modulation for the domestic hot water circuit, regardless of the heating.
Open several taps at the same time or check the water flow; a low flow can also cause the flame in domestic hot water to be weak without it being the fault of the gas valve.
- 04
The stability of the flame varies when increasing or decreasing the power, although it ignites well at the beginning.
Cause: The valve modulation system does not accurately follow the power demand indicated by the control unit.
Check if the fault occurs consistently within the same power range; if so, it will help you determine that it is the gas valve and not another cause.
Vaillant fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| F.26 | Fault: gas valve not functioning. | The stepper motor/coils of the gas valve (SIT 053462) are open, shorted, or disconnected, so the valve does not operate; check coil resistance/insulation and stepper motor signal/return from the PCB during the ignition attempt. |
| F.61 | Gas valve activation error. | The gas valve cannot be operated due to an internal fault (coils shorted/ground leakage) or wiring failure; confirm by measuring the resistance/insulation of coils, wiring harness, and control signal from the PCB. |
| F.62 | Gas valve disconnection delay. | The gas valve remains stuck/not sealed and takes time to close, maintaining the flame signal after the closure command; check for tightness and closing time (ionisation/analyser) and rule out internal leakage of the valve assembly. |
| F.28 | The appliance does not start: failed ignition attempts during startup. | The gas valve does not open or is incorrectly adjusted, preventing flow during ignition; check inlet pressure, control signal, and actual valve opening during the ignition sequence. |
| F.29 | The flame goes out during operation and subsequent ignition attempts fail. | This symptom may be related to the part, but it does not confirm that it is faulty. A technician must check the equipment and its inspection according to the manual before deciding on a repair or replacement. |
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.
