How to check if ref. 101271 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.
- Locate the reference printed on the body of the pressure gauge you have installed: it should indicate 101271.
- Check your boiler model on the nameplate and look for it in the list of compatible models on this page.
- Compare the connections and the body with the original part before installing.
- If you have any doubts, send us a photo of the screen printing via WhatsApp and we'll confirm it for you before you purchase.
Symptoms and faults resolved by pressure gauge 101271
The pressure gauge shows the pressure of the boiler circuit. These are the typical symptoms and what to do:
The needle doesn't move; it always stays at the same point no matter what I do with the installation.
Cause: The internal spring of the pressure gauge gets stuck due to rust or accumulated scale and stops responding to pressure changes.
Bleed a radiator or briefly open the filling valve and see if the needle reacts; if it doesn't move at all, the pressure gauge is suspect.
It indicates a pressure that doesn't match what the rest of the boiler says, for example, the low pressure fault triggers and the pressure gauge shows it's fine.
Cause: The mechanism loses calibration over time, and the reading deviates even though it continues to operate normally.
If the boiler has a digital pressure reading, compare it with the gauge before replacing it.
There is water dripping from the back, either from the fitting or the capillary that goes to the circuit.
Cause: The fitting gasket or the capillary itself degrades with the cycles of heat and pressure and starts to leak.
Dry the area thoroughly and tighten the fitting without forcing it; if the leak reappears in minutes, it's not just a matter of tightening.
The needle is stuck right at the red mark of 3 bar, even though you have bled and lowered the pressure.
Cause: It is common for it to get stuck at the stop if dirt or limescale has entered the mechanism after a temporary overpressure.
Gently tap the sphere with your finger, without applying force, and check if the needle drops; if it doesn't, the blockage is internal.
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.
