3-Way Valve Body Junkers/Bosch ZWN24-7MFA23/31 Ref. 8716011595
When you turn on the tap or the heating, the Junkers/Bosch ZWN24-7MFA23/31 3-Way Valve Body directs the water between the heating circuit and the domestic hot water circuit. If this valve has faults, you will notice that you have hot water but no heating, or vice versa, and there may even be a mixing of both circuits. This model is compatible with boilers from the Cerastar range, such as the ZWN 24-7 MFA, among others. A technician must confirm through diagnosis whether the valve needs to be replaced when you experience these issues to restore the proper functioning of your system.

How to check if ref. 8716011595 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 8716011595. 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 8716011595
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 between heating and domestic hot water.
Cause: The valve shutter is stuck due to limescale buildup after being idle.
Turn off the boiler and carefully move the actuator following the manual; if it does not move, the part is faulty.
- 02
There is hot water but the radiators are not heating, or vice versa.
Cause: The internal diverter is not sealing properly and the water is only going to one circuit.
Check if the problem is constant or intermittent; if it comes and goes, it could be the PCB instead of the gas valve.
- 03
There is a noise when switching modes in the motor area.
Cause: The coupling between the motor and the gas valve is worn or loose.
Gently touch the casing of the gas valve while switching to locate the noise.
- 04
A water leak appears at the valve after a period of operation.
Cause: The body gaskets lose elasticity due to heat and usage cycles.
Dry the area and observe if the dripping returns only when the boiler is on for a while; that indicates a problem with the gasket.
Junkers fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| d7 | Fault in regulating valve | A fault has been detected in the regulating valve, which may affect the pressure and flow of water in the system. If you notice that the boiler is not heating properly or shows fluctuations in temperature, it may be necessary to replace this 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.
