How to check if the ref. 39818552 is the part 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 39818552. 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 flow meter 39818552 resolves.

The flow meter detects the passage of water to activate the domestic hot water. These are the typical symptoms and what to do:

Common symptoms and faults

• 01

  The boiler does not ignite to provide hot water or heating, even though the tap is fully open and there is pressure.

  Cause: The flow detector does not close the contact, and the boiler understands that there is no water circulation, so it does not allow the burner to ignite.

  Check that there is no blocked inlet filter and that the installation pressure is within its range before declaring the part defective.

• 02

  The burner starts for a moment and then cuts off immediately, delivering water in bursts.

  Cause: The contact of the detector makes intermittent contact due to wear or internal dirt and sends intermittent flow signals to the boiler.

  Bleed the circuit to eliminate air and check if the cut coincides with pressure variations before replacing the part.

• 03

  The boiler shows a warning of lack of circulation even though the system is full and bled.

  Cause: The detector may get stuck in the open position and continue reporting a lack of flow even though water is circulating.

  Check that the pump is circulating normally and that no shut-off valves are partially closed before replacing the sensor.

• 04

  There is a small ring of moisture or dripping near the part, close to the connector.

  Cause: The plastic body of the detector ages with heat cycles and may lose tightness due to the gasket.

  Dry the area, turn on the boiler, and locate whether the water is coming from the detector itself or from a nearby fitting before purchasing the spare 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.
