Junkers Boiler Safety Valve ZWC24/28-1MFA - Ref. 87167714260
When you open the tap or turn on the heating, the safety valve of the Junkers ZWC24/28-1MFA boiler is responsible for releasing water if the circuit pressure exceeds the usual limit of 3 bar. If this part fails, you will notice that it drips continuously or does not discharge when it should, which can lead to pressure problems. This valve is compatible with several models from the Junkers Euromaxx ZWC range, such as the ZWC24-1MFA and ZWC28-1MFA, among others. It is recommended to replace it when it shows leaks or does not function properly.

How to check if ref. 87167714260 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 87167714260. 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 safety valve 87167714260 resolves.
The safety valve releases pressure when the circuit exceeds its setting. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
Water is continuously dripping, even with the boiler cold and the pressure within the normal range.
Cause: The internal seat of the safety valve does not close properly and allows water to pass through without the need to bleed.
Briefly activate the manual bleed lever and release it; if it continues to drip afterwards, the seat is worn out.
- 02
The boiler gradually loses pressure and the circuit needs to be refilled every few days.
Cause: The valve intermittently releases water because it doesn't seat properly, even though the pressure is within range.
Check for any puddle or trace of water under the valve or its drain before looking for the leak elsewhere in the installation.
- 03
When operating the manual bleed lever, no water comes out or very little does.
Cause: The internal mechanism is seized up with lime and does not release properly even when the lever is operated.
Operate the lever several times carefully and check if it releases water; if nothing comes out, the mechanism is blocked.
- 04
Water leaks from the valve just when the boiler heats up strongly.
Cause: The valve opens because the circuit pressure exceeds the safety limit as the hot water expands.
Compare the pressure when cold and when hot on the boiler's pressure gauge before assuming the valve is faulty.
Fault codes from Junkers that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F7 | Problems with the ignition of the boiler. | The ionization signal is incorrect, which may cause the boiler not to ignite. If the safety valve is not functioning properly, it may not be supplying the necessary gas for proper combustion. Check the valve to ensure it is operational. |
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.
