Hello, I have a brand new SV06 Plus Ace that got jammed on its second print. I had a spare nozzle, so I cleared out the extruder and inserted the new one. When I try to calibrate again I get the Not Heating error. In fact, it is not heating at all: stuck at room temperature. I followed the YT video to remove the extruder assembly and take it apart. I could not see any signs of obvious damage, such as detached wires, etc. Is there anything you can recommend? If not, I’ll just return the printer. ---

When you changed the nozzle, you could have damaged the ceramic heater…others before you have done the same not knowing where & where not to put the pliers or wrench. ![Capture](https://canada1.discourse-cdn.com/flex030/uploads/sovolforum/original/2X/2/26865382738445abcde5907825b92720d03f22f6.jpeg) ---

Is the solution to get a replacement Brass Nozzle Kit, (approx $21 USD)? I used the supplied wrench and followed the YT instructions. They did not specify any details about what might be broken. It seems like a bad design. ---

That’s for you to decide. you will have to pull off the sock & the metal clip holding the heater to see if it is in fact cracked or not. ---

Thanks for your help Lion. In the company’s YT video, they show the tech grasping the head in two ways: on the round shaft, and on the heater block. It looks safer to hold it on the round shaft since that’s metal? Is that a correct assumption? Can you tell me the right tightening torque for the nozzle? ![image](https://canada1.discourse-cdn.com/flex030/uploads/sovolforum/original/2X/0/057306e679f84a91b63282e4fb480c9830d86881.jpeg) ---

@Lion you were right. The heater element got cracked. Sovol have been excellent and is sending a replacement!
