Guide

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.

  1. Locate the reference printed on the body of the pressure gauge you have installed: it should indicate 101271.
  2. Check your boiler model on the nameplate and look for it in the list of compatible models on this page.
  3. Compare the connections and the body with the original part before installing.
  4. 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.
Diagnosis

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.

Before purchasing
  • This unit does not have legible markings in the available photos: only the rear body and the capillary are visible, without a dial or text.
  • The manufacturer of the part is not listed, and no commercial code could be confirmed.
  • Check that the scale (0-3 bar, green zone up to approx. 1.8 bar) matches your pressure gauge before ordering it.
Frequently Asked Questions

Frequently Asked Questions about Pressure Gauge 101271

Is this pressure gauge Ref. 101271 suitable for a Vaillant VUW 282-5?
Yes, the VUW 282-5 is on the list of compatible boilers for this reference.
Who manufactures the pressure gauge for the Vaillant VMW 28/362-5?
Not available: the available photo is of the rear view, with no visible dial or legible text.
What pressure does the green zone of the Vaillant VM 240-5 manometer indicate?
Up to approximately 1.8 bar within a scale of 0 to 3 bar, with a red mark at 3 bar.
How do I check if Ref. 101271 is the one for my Vaillant VU 240-5?
It cannot be confirmed by screen printing because it is not legible in the available photos; compare the pressure scale (0-3 bar) with the part mounted on your boiler.
Is the same part suitable for the Vaillant VMI 280-7 and the VUW 240/5?
Yes, both models are on the list of compatible boilers for this reference.
