How to check if ref. 181057 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Locate the full label or reference on the part installed in the boiler; do not identify it by shape alone.
- Note the boiler’s complete model and serial number.
- Compare volume, diameter, depth, bracket position and connection type.
- If any detail is missing or differs, please send photos of the installed part and its connection before purchasing.
Symptoms that require diagnosis in the expansion vessel 181057
The expansion vessel absorbs the expansion of water when heated. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
System pressure falls repeatedly
Cause: Loss of pre-charge or a damaged diaphragm is possible, but leaks, vents, or valves can cause the same symptom.
Avoid repeatedly topping up the circuit. A technician should isolate and depressurise it, then measure the pre-charge with suitable instruments.
- 02
Pressure rises quickly as the system heats
Cause: A vessel with no pre-charge may stop absorbing expansion, although other causes are possible.
Record cold and hot pressure readings and have a professional check the vessel and filling valve.
- 03
The safety valve discharges water
Cause: It may be reacting to overpressure linked to the vessel, but it can also be dirty, damaged or affected by the filling circuit.
Do not handle the valve while hot. A professional should inspect the vessel, valve and circuit before parts are replaced.
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.
