3-Way Valve Motor Wolf CGB K 24 Ref. 2744052
The Wolf CGB K 24 3-Way Valve Motor is a component that controls the flow of water between the heating circuit and the domestic hot water circuit. Its function is to ensure that the water is directed correctly, preventing both circuits from mixing. When it fails, the user may notice that there is hot water but no heating, or vice versa. This motor is compatible with several boiler models, including CGB-11, CGB-20, CGB-24, among others. It is recommended to replace it when symptoms of malfunction occur or the fault code 32: Error in power supply 24 VAC is detected.

How to check if the ref. 2744052 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 2744052. 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 2744052 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 provide hot water or heating, depending on how the gas valve has become stuck.
Cause: The motor does not change position and the valve remains fixed in its last location.
Change the mode from the boiler panel and observe if the motor tries to move or remains still.
- 02
There is noise from the motor when it moves, but the boiler takes too long to switch between domestic hot water and heating.
Cause: The motor is having difficulty turning, which indicates that the reduction gear or the valve shaft is more resistant than usual.
Check for any visible moisture or rust on the motor housing, which could indicate a nearby leak that is hindering the mechanism.
- 03
The valve gets stuck in an intermediate position and the boiler does not heat the water or the radiators properly.
Cause: The motor has lost the position reference because it does not reach either of the two limit switches.
Before changing the motor, visually check if the valve stem is bent or if there is limescale buildup on the shaft.
- 04
When turning on the boiler, a knocking sound is heard from the gas valve that wasn't present before.
Cause: The internal gears of the motor are worn and transmit rotation irregularly instead of a continuous movement.
If you can access a similar boiler without a fault, compare the noise to confirm that it is not a normal sound of the installation.
Fault codes for Wolf that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 32 | 24 VAC power supply error | The motor of the 3-way valve (24 VAC) may short circuit, become stuck, or excessively draw from the 24 VAC line, taking the power supply out of range and causing the 32 fault code; check by measuring voltage/current at the motor connector and try disconnecting it to see if the error disappears. |
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.
