How to check if the reference 5699941 is the part 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 5699941. 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 on the manometer 5699941
The manometer shows the pressure of the boiler circuit. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The aquastat does not cut off or activate the circuit at the temperature it should.
Cause: The internal electrical contact is stuck or not closing properly, so the control unit does not receive the command to act.
Check that the bulb is properly inserted into the immersion sleeve and has good thermal contact; a poor insertion can give incorrect readings before replacing the part.
- 02
The boiler does not start or does not stop at the expected temperature.
Cause: The sensor of the aquastat is out of calibration and sends the cut-off or activation command out of range.
Compare the actual water temperature with an external thermometer at the same point before replacing the aquastat.
- 03
There is a water leak in the rear threaded fitting.
Cause: The gasket or the brass body of the water heater has lost tightness over time.
Tighten the fitting carefully and check the sealing gasket before considering that the part is perforated.
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.
