How to check if the part number 05234200 is the correct one for your boiler.

What determines it is not the boiler model, but the reference printed on the part you already have installed.

1. Find the reference printed on the installed part and check whether it matches the catalogue reference 05234200. If it is not visible, do not identify the part from its shape alone.
2. Check the full boiler model on its data plate and look for it in the model associations on this page.
3. Compare the connections and physical body with the original part before installation.
4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.

Symptoms and faults that the pressure gauge 05234200 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 does not move or remains fixed.

  Cause: The pressure bellows of the manometer is stuck and does not show the actual reading.

  Bleed a radiator and check if the pressure drops; if the needle does not move, the part is the cause.

• 02

  There is no temperature reading, even though the water is hot.

  Cause: The temperature element has failed on its own.

  Touch the supply pipe near the boiler to confirm that there is actual temperature before changing the part.

• 03

  The glass of the dial is broken or heavily scratched.

  Cause: A blow or the passage of time has damaged the protective glass.

  Check if it is a superficial scratch that can be polished or if the glass is cracked.

• 04

  There is moisture or dripping around the thermometer.

  Cause: The sealing gasket has lost elasticity due to continuous heat.

  Dry the area and observe for a few minutes with the boiler running to confirm that the leak is from the part.

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.
