How to check if the ref. 61312663 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 61312663. 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 61312663 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 does not switch properly between heating and domestic hot water.
Cause: The motor or the internal mechanism of the gas valve does not move the stem to the correct position.
Open a hot water tap with the heating on and check if the radiators release temperature while the domestic hot water is flowing out.
- 02
Cold or lukewarm water comes out when opening a tap while the heating is on.
Cause: The valve is stuck halfway between the two positions and distributes the flow poorly.
Listen for the click or the hum of the valve motor when opening the tap; if you don't hear anything, it may not be receiving the command.
- 03
Water is leaking from the body of the gas valve or the hydraulic block.
Cause: The internal seals of the block have lost tightness over time.
Locate whether the leak is coming from the body of the gas valve or from a nearby connection, and tighten the fitting nuts before replacing the part.
- 04
The heating cools down every time a hot water tap is opened.
Cause: The valve prioritizes domestic hot water but does not return to the heating position when the tap is closed.
Turn off the hot water tap and wait a couple of minutes to see if the boiler resumes heating by itself.
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.
