Ferroli Bluehelix Pressure Gauge Ref. I39818210
In Ferroli Bluehelix boilers, the pressure gauge Ref. I39818210 measures and controls the circuit pressure. If this part fails, you will notice incorrect readings, which may cause the boiler to lock out due to a false lack of pressure or not regulate the temperature properly. This pressure gauge is compatible with models from the DOMICOMPACT, DOMIPROJECT, and OPTIMAX ranges, among others. A technician must confirm through diagnosis whether it needs to be replaced when you observe that the pressure is not accurately reflected on the indicator.

How to check if ref. I39818210 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference I39818210. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms that require diagnosis on the manometer I39818210
The manometer shows the pressure of the boiler circuit. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The pressure gauge stays at zero even though the boiler is full of water.
Cause: The internal clock does not register the actual pressure because it is stuck or broken.
Confirm that the boiler accepts water normally using the filling valve before discarding only the pressure gauge.
- 02
You bleed or fill the circuit and the needle doesn't react, it stays the same.
Cause: The shaft that moves the needle is stuck and does not follow the pressure changes in the circuit.
Repeat the filling procedure a couple of times while observing the needle; if it doesn't move, the fault is with the pressure gauge.
- 03
The sight glass is damaged and does not allow the pressure scale to be seen.
Cause: A blow or the passage of time has deteriorated the display, although the measuring mechanism may still be functioning.
Check if the damage is only to the glass (visible scratch or break) and without moisture inside, which would indicate an aesthetic issue.
- 04
There is a water leak at the connector where the pressure gauge is screwed in.
Cause: The gasket or the connection thread has lost tightness due to years of pressure and heat cycles.
Tighten the connector carefully and dry the area; if the dripping reappears, the leak is coming from the part.
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.
