Vokera Flowmatic boiler problem with oil nozzle

Hello Folks,

I have bought and installed a Vokera Flowmatic boiler five years ago. From last few days, I am noticing that its nozzle is having some issue and due to this, it is not working properly. Furthermore, oil is dripping from the nozzle. What is wrong with the nozzle? Someone please tell me the ways of fixing it.

Thanks for your guidance

Hi John, firstly I would like to share some possible reasons behind this issue, as it is impossible to fix any problem without knowing the exact reasons. Secondly, there is no need to worry about because it is a quite common problem.

  1. Chocked nozzle
  2. Pump filled with air
  3. Out of order drive or CHP
  4. Damaged electrical shutoff regulator
  5. Oil is not present in the central heating pump

In order to fix this problem, firstly check or even refill an expansion tank. It is important to examine or clean all the controllers & filters of the boiler as well. In worst-case scenario, replace the boiler’s oil nozzle. Well, it is always better to seek help from an experienced boiler engineer.
