How to check if ref. 8707208004 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 8707208004.
- 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 8707208004
The pressure gauge shows the pressure of the boiler circuit. These are the typical symptoms and what to do:
The pressure gauge stays at zero even though the system is filled and pressurized.
Cause: The internal bellows have broken or seized and no longer transmit the actual circuit pressure to the needle.
Bleed or refill the circuit using the filling key and observe the needle; if water enters with pressure and it doesn't respond, confirm the fault of the pressure gauge.
The needle does not move or gets stuck halfway through its range.
Cause: The mechanism seizes over time or due to internal dirt, especially if the boiler has been unused for a long time.
Gently tap the glass while bleeding the circuit; if it still doesn't move with the circuit clearly filled, replace it.
The sphere is scratched or cloudy, and the scale is not clearly visible.
Cause: The front glass or plastic gets scratched from mounting impacts or fogs up due to moisture inside the body.
Check if the fogging disappears when the area dries; if it persists or there are cracks, the body of the pressure gauge is damaged, not just the surface.
Water is leaking from the pressure gauge connection to the circuit.
Cause: The gasket or the thread of the connection deteriorates over time, and water leaks from there, not from the pressure gauge mechanism.
Tighten the connection with a wrench and check if the leak stops; if it continues to drip after tightening, it's the gasket and there's no need to replace the entire pressure gauge.
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.
