3-Way Valve Cointra Excellent D Micro LN 24 E - 4515195-04 / 4515293
The Cointra Excellent D Micro LN 24 E - 4515195-04 / 4515293 3-Way Valve is a component that switches water between the heating circuit and the domestic hot water circuit. When it fails, the user may notice that there is hot water but no heating, or vice versa, and there may even be a mixing of both circuits. This valve is compatible with boilers such as the Cointra Excellent D Micro LN 24 E and the Ferroli Divatech Micro LN F24D, among others. A technician must confirm through diagnosis whether the valve needs to be replaced when these symptoms of improper operation occur.

How to check if the ref. 39842110 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 39842110. 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 that require diagnosis in the 3-way valve 39842110
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 heating works but there is no hot water at the tap, or vice versa.
Cause: The valve does not change position and does not allow water to flow to the corresponding circuit.
Force a demand for hot water with the heating off and check if the valve motor moves; if it doesn't move, check the motor wiring before the valve.
- 02
The hot water comes out intermittently, it cuts off or mixes with the heating water.
Cause: The internal shutter does not seal properly and allows water to pass through the closed path.
Compare the tap temperature in domestic hot water mode and in heating mode: if you notice mixing in both cases, the gas valve is the cause.
- 03
Water is accumulating or dripping at the base of the boiler, near the gas valve.
Cause: The seals of the valve lose elasticity over time and may start to leak water.
Dry the area and check after a complete cycle of heating and domestic hot water where the first drop appears, so as not to confuse it with condensation.
- 04
A buzzing sound, a repeated click, or vibration is heard when switching from heating to domestic hot water.
Cause: The valve motor is forcing the rotation because the internal mechanism is not moving smoothly, usually due to limescale buildup or wear.
Listen to the noise in several cycles: if the click repeats many times before changing, the motor is having difficulties, but it is not necessarily broken.
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.
