Pressure Gauge Beretta Mynute Green 28 CSI
In the Mynute Green boilers, the pressure gauge Beretta Mynute Green 28 CSI (reference 10029421) measures and controls the pressure of the circuit. If it fails, you may notice incorrect readings, which can 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 the Mynute Green 28 CS and 28 CSI models, among others. A technician must confirm through diagnosis whether it needs to be replaced when you observe these anomalies in operation.

How to check if the part R10029421 is the one 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 R10029421. 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 in the manometer R10029421
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 always stays at zero, as if there is no pressure in the circuit.
Cause: The pressure gauge mechanism does not detect the actual water pressure.
Fill the circuit with the filling key until 1-1.5 bar and check if the needle rises from zero.
- 02
The needle is stuck at a fixed point and does not move regardless of what happens with the installation.
Cause: The internal shaft has seized, usually due to the passage of time without use.
Gently tap the gauge's dial to see if the needle detaches before replacing it.
- 03
The glass is broken or fogged on the inside, making it difficult to read the pressure.
Cause: A blow or the entry of moisture has damaged the glass or the dial.
Check for condensation between the glass and the sphere, indicating that water has entered and it is not just superficial dirt.
- 04
There is a water leak from the connection fitting of the pressure gauge with the boiler.
Cause: The gasket of the fitting has deteriorated due to the cycles of pressure and temperature.
Dry the fitting well and tighten it carefully, without forcing, to rule out that it is just a loose gasket before replacing the entire 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.
