    Hi @ShaunNo43, here is a list with error messages. There is mention of ER01, but I am not entirely sure about ER03. Do you perhaps have a photo of the error message, or can you describe what happens when you get it? What is your Ultimaker trying to do, except well.. printing?

    I have fixed it by lowering the fan from 50% to 20%. While doing this I monitor the nozzle temperature during the building the part.

    At 50% fan speed, the nozzle that was initially at the correct temperature was loosing heat sometghing like 1 degres every 2 minutes, end up at a too low temperature and the machine would stop for me.

    Fan at 20 % maintain the nozzle temperature along the full time of the build.

    You shouldn't have to lower the fan unless you are printing for example with a 0.8mm nozzle and 0.3mm (or thicker layers).  Or if you are printing an extra hot material with a large nozzle.

     

    If you are printing PLA at default speeds and nozzle and layer height you shouldn't need to lower the fan.  It indicates the nozzle is probably touching the metal shroud that holds the side fans.

     

    Maybe you or someone else took the head apart and put it together wrong?  You want to make sure the brass heat block isn't touching the metal fan holder.

     

    There is a round nut above the nozzle.  If you heat the nozzle to 180C you can rotate that nut without taking much apart (remove one of the 4 screws).  Rotate it clockwise looking down from above (turn it to the right).  This will raise up the heat block and also the nozzle.
