How to check if the ref. 65108293 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 65108293. 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 3-way valve 65108293 resolves.
The 3-way valve diverts water between heating and domestic hot water. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler heats domestic hot water but not heating, or vice versa, intermittently.
Cause: The electric motor of the gas valve does not have enough power or stops halfway and does not complete the circuit change.
Check if the valve takes a long time to react or does not move at all with a domestic hot water tap open before considering it faulty.
- 02
Noise or clicking in the valve when switching between domestic hot water and heating.
Cause: The internal gears of the motor are worn out or the shutter hits at the end of its travel.
Confirm that the noise is coming exactly from the gas valve and not from another nearby part by touching the boiler with your hand at the moment of the change.
- 03
Water leak from the body of the three-way valve
Cause: The internal O-rings wear out with the heat and pressure cycles typical of this valve.
Check if the leak comes from a threaded joint, which sometimes only needs to be tightened before replacing the entire gas valve.
- 04
The boiler display shows a switching or valve error.
Cause: The control board detects that the gas valve does not reach the expected position by the limit microswitch.
Note the exact fault code and check it before purchasing; some codes may indicate a problem in the control board and not in the gas valve.
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.
