Thermomanometer Junkers Eurosmart ZWA 24 28 0 4 Bar 0 120 C Ref. 87161423950
The Junkers Eurosmart ZWA 24 28 0 4 Bar 0 120 C Ref. 87161423950 thermometer manometer is a gauge that measures the pressure and temperature of the boiler circuit. Its main function is to ensure accurate readings; when it fails, it can lead to incorrect readings, which may cause the boiler to lock out due to a false lack of pressure or not properly regulate the temperature. This component is compatible with Junkers Eurosmart boilers ZWA 24 and ZWA 28, among others. It is recommended to replace it when the readings are incorrect or if it does not respond to changes in the system.

How to check if the ref. 87161423950 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 87161423950. 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 87161423950 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 of the thermomanometer gets stuck, even though the boiler heats normally.
Cause: The capillary of the temperature bulb has lost the internal fluid and does not transmit the reading to the dial.
Check that the two capillaries are not bent, crushed, or have signs of leakage before replacing the sensor block.
- 02
The manometer shows a pressure that does not match what you check when filling or bleeding the circuit.
Cause: The pressure capillary of the sensor block has lost tightness and does not transmit the signal properly to the gauge.
Check for moisture or dry fluid residue around the threaded fitting before declaring the part faulty.
- 03
The needle jumps or gets stuck at a point on the dial.
Cause: The internal mechanism of the sensor block has seized up with use and the passage of time.
Gently tap the dial to see if the needle releases; if it doesn't, the sensor block is the suspect.
- 04
There is no reading of either temperature or pressure, as if the thermometer were dead.
Cause: The threaded fitting of the sensor block does not seat properly against the boiler and loses the original pressure reference.
Tighten the fitting and bleed the air from the area before replacing the complete block.
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.
