How to check if the ref. 87160102470 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 87160102470. 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 87160102470

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

  The valve drips after bleeding the circuit or operating the test lever.

  Cause: The seat does not close properly after the operation, especially if there is limescale buildup.

  Wait a few minutes after bleeding; if the dripping persists, operate the lever a couple more times before replacing it.

• 02

  The pressure in the circuit decreases over time and you don't see any leaks in the radiators or pipes.

  Cause: The valve may be slowly leaking water through the discharge pipe without you noticing.

  Check the flue outlet for moisture or limescale residue before looking at other parts of the circuit.

• 03

  The boiler requests to refill pressure more often than usual.

  Cause: If the valve does not close properly, the circuit continuously loses water and you have to compensate for it with the filling tap.

  Note how often it needs to be refilled; if it's every few days, check if the gas valve is leaking before looking for the leak elsewhere.

• 04

  The valve is leaking with the boiler cold, before the temperature rises.

  Cause: This indicates that the seat does not seal properly at rest, not that there is a momentary overpressure when heating.

  Check if the dripping occurs in cold water as well or only in hot water; this helps to differentiate between a valve issue and circuit pressure.

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.
