Connection Piece 3-Way Valve Vaillant VMW 282/2-5 Ref. 019392
If you notice that you have hot water but no heating, or vice versa, you may need the 3-way valve connection part Vaillant VMW 282/2-5. This valve is responsible for directing water between the heating circuit and the domestic hot water circuit. If it fails, it can cause the mixing of both circuits or the lack of one of them. It is compatible with several Vaillant boiler models, such as the VMW 21/245/4-5 and the VM 240/3-5, among others. It is advisable to replace it when you experience issues with the distribution of hot water and heating.

How to check if the reference 019392 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 019392. 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 019392 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
There is a drip at the joint of the 3-way valve with the rest of the circuit.
Cause: The brass fitting of this connection piece is leaking due to wear of the gasket or corrosion.
Dry the area, check that the joint is properly tightened, and take another look after a while of operation.
- 02
The radiators are heating less than normal even though the boiler is working fine.
Cause: This part channels the flow of water to the heating circuit, and an internal blockage due to limescale reduces the flow rate.
Bleed the radiators and check the circuit pressure before attributing the flow fault to this connection.
- 03
A white ring or limescale residue can be seen around the connection.
Cause: Limescale builds up in the brass fitting over time and eventually forces the gasket until it starts to leak.
Check the water hardness of the installation; if it is high, the leak may recur even if you only change this part.
- 04
There is a noticeable vibration or rattling in the pipe where this part is mounted.
Cause: A gap in the fitting allows water to flow with turbulence at that connection point.
Check that the nearby pipe clamps and supports are properly secured before assuming that the fault is with this 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.
