How to check if ref. 87172080280 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 87172080280.
- 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 87172080280
The pressure gauge shows the pressure of the boiler circuit. These are the typical symptoms and what to do:
The needle is stuck on a number and never moves, whether you load or bleed water.
Cause: The inner Bourdon tube has seized, something common when dirt or lime has entered through the thread.
Gently tap on the glass with the boiler turned off; if the needle doesn't react at all, the mechanism is blocked.
The pressure indicated by the pressure gauge does not match what you know the installation has.
Cause: The mechanism has lost precision over time and no longer calibrates the reading accurately.
Compare the reading with another reference manometer at the same load point before considering the instrument faulty.
Water is leaking or there is a ring of rust on the connection thread of the pressure gauge.
Cause: The thread's seal has deteriorated and water is leaking at low pressure.
Check if tightening the fitting a bit more solves the leak before buying a new one; if it continues to drip, it's the part.
The dial is broken or so fogged up that no numbers can be read.
Cause: It is physical damage to the body or moisture entering the mechanism, not a fault with the boiler.
Check if you can still see the needle moving even if you can't read the number clearly; that indicates the mechanism itself is working.
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.
