How to check if ref. 6040211 is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

1. Find the reference printed on the installed part and check whether it matches the catalogue reference 6040211. 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 that require diagnosis in the safety valve 6040211

The safety valve releases pressure when the circuit exceeds its setting. These are the typical symptoms and what to do:

Common symptoms and faults

• 01

  Water continuously drips from the safety valve, even when the boiler is off.

  Cause: The valve seat does not seal and allows water to escape even without pressure spikes.

  With the system cold, check the pressure on the gauge: if it is within the normal range and it continues to drip, the fault is in the seal, not the pressure.

• 02

  The heating circuit loses pressure and needs to be refilled from time to time.

  Cause: A slow and steady leak through the valve can go unnoticed and result in that progressive loss.

  Also check the expansion vessel and bleed the radiators before assuming it's the valve.

• 03

  The valve leaks water just when the boiler heats strongly.

  Cause: If the circuit exceeds the set pressure of 3 bar at that moment, the valve acts as it should to protect the installation.

  Check the cold fill pressure and the condition of the expansion vessel before replacing the valve: if it is discharged, the pressure rises too much when heating.

• 04

  After bleeding the valve, it continues to drip and doesn't fully close.

  Cause: Lime deposits on the seat can prevent the valve from resealing after bleeding.

  Bleed several times in a row with force; if the jet cleans the seat and then closes, it wasn't necessary to replace it.

Sime fault codes that require diagnosis

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.
