Pressure Gauge Ariston Microgenus 27 MFFI Ref. 65100695
Pressure Gauge Ariston Microgenus 27 MFFI Ref. 65100695 is a device that measures and controls the pressure of the boiler circuit. When this part fails, you may notice incorrect readings, which can lead to the boiler locking out due to a false low pressure or not regulating the temperature properly. This pressure gauge is compatible with models such as Microgenus 23 MFFI, Microgenus MF27, Microgenus Plus, among others. It is recommended to replace it when you observe that the readings are not accurate or if the boiler is experiencing operational issues related to pressure.

How to check if ref. 65100695 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 65100695. 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 65100695 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 pressure gauge doesn't show anything, the needle stays at zero no matter what.
Cause: The internal mechanism has stopped responding to the circuit pressure, whether it is high or low.
Refill water using the filling key and observe if you notice the boiler gaining pressure even if the needle doesn't move; if so, the fault is in the pressure gauge.
- 02
The needle indicates an unusual pressure, either very high or very low, and stays fixed there.
Cause: The mechanism that moves the needle has deformed or become blocked with debris from the circuit.
Bleed a radiator to release air and check if the reading changes; if it remains exactly the same, the pressure gauge is not reflecting the actual pressure.
- 03
You have to refill water very often because the pressure gauge always shows low pressure.
Cause: If you really lose pressure frequently, there may be a leak in the circuit, and the pressure gauge might not be the source.
Before replacing it, check the radiators, bleeders, and the filling valve itself for moisture; if there's no leak and the pressure doesn't increase when refilling, suspect the pressure gauge.
- 04
You don't know if the boiler has enough pressure because the gauge is not clearly readable.
Cause: The glass or casing of the pressure gauge is damaged and does not allow the needle to be seen clearly.
First, confirm the exact model of your boiler on the compatibility list: this part has no visible brand in the photo and there are several similar versions.
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.
