Ferroli Domina Oasi F30E Pressure Gauge Ref. 39806330
If you notice incorrect pressure readings on your boiler, the Ferroli Domina Oasi F30E pressure gauge Ref. 39806330 is the solution you need. This component measures and controls the pressure of the circuit, and if it fails, it can cause the boiler to lock out due to a false lack of pressure or not regulate the temperature properly. It is compatible with models such as Domina Oasi F24, Domina Oasi C24, and Domicompact F30, among others. It is recommended to replace it when you observe abnormal readings or issues with the operation of the boiler.

How to check if ref. 39806330 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.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 39806330. 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 and faults that the pressure gauge 39806330 resolves.
The manometer shows the pressure of the boiler circuit. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The needle is at zero or does not show pressure even though the boiler is full and operating.
Cause: The internal measuring mechanism is not responding, usually due to a broken bellows or a blocked duct.
Check with the filling key that there is indeed pressure in the circuit before considering that the pressure gauge is faulty.
- 02
The needle remains stuck at a fixed point no matter how much the actual pressure in the circuit changes.
Cause: The mechanism has jammed and does not reflect the pressure changes in the needle movement.
Bleed the air from a nearby radiator and observe if the needle moves with the drop in pressure, even if it's slightly.
- 03
The scale is not visible because the glass is broken or fogged up on the inside.
Cause: Moisture has entered the inside of the glass, usually due to a previous leak or accumulated condensation.
Check if the fogging disappears after leaving the boiler running for a few hours before replacing the part.
- 04
There is a constant drip right at the brass fitting where the pressure gauge is connected.
Cause: The gasket of that fitting has lost its seal over time or due to insufficient tightening.
Tighten the fitting with an appropriate wrench without overdoing it; if the dripping persists after re-tightening, the leak is from the pressure gauge itself.
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.
