How to check if ref. 8716143116 is the part for your boiler

- 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 circulator pump 8716143116 resolves.
The circulation pump circulates the water in the heating circuit. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The circulator does not start or makes a strange noise just when trying to start.
Cause: The rotor may be jammed due to sediment or prolonged inactivity.
Try to free the shaft by manually turning it with a screwdriver in the front slot before replacing it.
- 02
The boiler ignites normally but does not heat.
Cause: The water is not circulating because the pump is not pushing, even though the rest of the system is working fine.
Make sure that the pump is actually spinning, noticing the slight vibration or hum of the motor, before replacing it.
- 03
Water appears at the base of the circulator.
Cause: The shaft seal has worn out and is allowing water to pass into the electrical part of the motor.
Dry the area, let the boiler run for a while, and check if the moisture reappears right on the circulator body.
- 04
The rotor is clearly blocked and does not turn even by hand.
Cause: It is usually due to lime or sediment buildup inside the pump body, especially after months of inactivity.
Before replacing it, try forcing the rotation with a screwdriver on the central screw of the shaft; sometimes it releases.
Fault codes from Junkers that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| The reset button flashes at 1 Hz (once per second) | General fault indicated by the reset LED at 1 Hz. | If the circulating pump is blocked or faulty, there is no circulation and the boiler goes into lockout due to overheating or lack of flow; check for 230 V voltage at the pump during demand and unblock/check rotation by removing the central screw and turning the shaft. |
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.
