How to check if ref. 125892245 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 125892245.
- 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 125892245
The pressure gauge shows the pressure of the boiler circuit. These are the typical symptoms and what to do:
The pressure gauge remains stuck at the same reading, it doesn't respond even if the circuit pressure changes.
Cause: The internal mechanism seizes up over time, or the duct connecting it to the circuit becomes clogged with limescale.
Drain some water through the bleed valve of a radiator and check if the needle moves before replacing it.
The pressure gauge shows a pressure that doesn't match what the boiler is actually doing.
Cause: When the connection duct is partially blocked, the needle lags behind the actual pressure of the circuit.
Compare the reading with the actual behavior of the boiler (if it resets when refilled, if it warns of low pressure) before relying solely on the needle.
Water is leaking where the pressure gauge connects to the pipe.
Cause: The gasket or the threading of the fitting loses its seal with the heating and cooling cycles of the circuit.
Check with dry paper if the leak is coming from the fitting or a nearby pipe before replacing the pressure gauge.
The dial appears broken, scratched, or foggy inside, and the scale is not visible.
Cause: A blow or moisture entering through the glass seal leaves the interior damaged or fogged up.
Check if the condensation is on the outside (can be wiped off) or inside the glass (cannot be wiped off); only in the second case does it need to be replaced.
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.
