Guide

How to check if the reference 0020148381 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.

  1. Find the reference printed on the installed part and check whether it matches the catalogue reference 0020148381. If it is not visible, do not identify the part from its shape alone.
  2. Check the full boiler model on its data plate and look for it in the model associations on this page.
  3. Compare the connections and physical body with the original part before installation.
  4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Diagnosis and fault codes

Symptoms and faults that the gas valve 0020148381 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.

CodeFaultDiagnosis and solution
F.26Fuel valve not functioning.The stepper motor/actuator of the gas valve is disconnected or faulty; check the power supply and continuity of the actuator and harness to the valve connector.
F.27Flame simulation (flame detection when it shouldn't).The leaking gas solenoid valve may allow gas to pass when the burner is off; check the valve's tightness/closure (closure test) and rule out moisture in the electronics.
F.28Ignition fault on start-up.The faulty/closed gas valve prevents supply during the spark; check the opening order (voltage at connector) and gas pressure/flow during the ignition sequence.
F.29Flame loss during operation (failed re-ignition).A fault/intermittency in the gas valve or its adjustment can cut or fail to modulate the flow; check modulation/stability of pressure and wiring to the valve.
F.53Combustion regulation fault / unexpected gas mass.The gas valve does not properly regulate the requested flow; check dynamic pressure, Venturi/mass sensor, and valve operation.
F.54Gas supply fault (start-up) / insufficient gas.A faulty gas valve may not allow passage despite having pressure; check inlet pressure and effective opening of the valve during start-up.
F.56Fault in combustion component (CO protection/regulation).Defective contact or fault in the gas valve; if after checking the wiring the fault reappears, the valve is considered defective. Verify control signal, continuity/insulation, and modulation response.
F.61Fault in the activation/command of the gas valve.Coils to ground/short circuit or faulty valve prevent its operation; check control voltage at connector, continuity/insulation of coils, and if there is correct signal and it does not open, replace the valve.
F.62Delay in the closing of the gas valve.Internal leak or stuck solenoid cause the flame to take time to extinguish; check that the ionisation signal drops when closure is commanded and perform a valve tightness/closure test.
F.88Fault: gas valve (connection).The valve is disconnected/improperly connected or there is a short circuit in the harness; check the plug, polarity, and continuity of the wiring to the valve assembly.

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.
