Pressure Gauge Junkers ZWE 24 3 Mfad 31 Ref. 8716761188
The Junkers ZWE 24 3 Mfad 31 pressure gauge measures and controls the pressure of the boiler circuit, ensuring proper operation. When it fails, it may display incorrect readings, causing the boiler to lock out due to a false low pressure or not regulate the temperature correctly. This pressure gauge is compatible with several boilers in the ZWSE range, such as the 23-3 MFA and 28-3 MFA models, among others. It is recommended to replace it if you notice issues with pressure readings or the boiler's performance.

How to check if the ref. 8716761188 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 8716761188. 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 8716761188 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 boiler shuts down and displays a pressure fault, even though the actual pressure in the circuit is correct.
Cause: The contact of this switch does not align with the scale of the part and sends a fault signal even though the circuit is in good condition.
Compare the pressure indicated by the filling system with the cut-off point that this part should display according to its scale, before replacing it.
- 02
The pump or the burner do not respond adequately to changes in pressure or temperature in the circuit.
Cause: The coiled capillary of this component has lost the sensing fluid and no longer transmits the correct signal to the control board.
Check that the capillary is not crushed, bent at a sharp angle, or has oil residue around it, which would indicate a leak, before replacing it.
- 03
There is moisture or a drop at the point where this part connects to the water circuit.
Cause: The gasket of this switch deteriorates with pressure cycles and loses tightness in that area.
Dry the area, let the boiler run for a while, and check again: if the drop reappears only there, the leak comes from the part and not from a nearby fitting.
- 04
The boiler stops immediately when turned on, before reaching working temperature or pressure.
Cause: If the contact of this switch gets stuck or does not close when at rest, the control unit detects a fault from the very beginning.
With the boiler cold and the circuit at normal pressure, use a multimeter to check if the contact of this part is closed at rest, before replacing it.
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.
