How to check if ref. 65100296 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.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 65100296. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms and faults that the flow meter 65100296 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
When opening the hot water tap, the boiler does nothing.
Cause: The flow switch does not detect sufficient flow and does not send the signal to ignite the burner.
Check the mains water pressure and make sure that the inlet filter is not clogged with limescale before replacing the part.
- 02
The water comes out hot for a moment and then repeatedly cools down while the tap is open.
Cause: The detector's palette oscillates due to internal dirt or because of a flow just enough to keep the contact closed.
Open the tap to the maximum and check if the problem disappears; if it persists, check the filter before replacing it.
- 03
The boiler heats the radiators, but it does not provide hot water at the taps.
Cause: This component only operates in the domestic hot water circuit: if the contact does not close, there is no ignition command for domestic hot water.
Check for lime or residues in the brass fitting of the part before considering it faulty.
- 04
You see a small water leak in the brass fitting of the sensor.
Cause: The fitting or the sealing gasket wears out with the use and pressure of the circuit.
Check the tightening of the fitting and the condition of the gasket before replacing the entire 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.
