ER998 - An unspecified error has occurred

This is an error that is not recognized by your Ultimaker S-line printer. It can occur when there is a mismatch between the installed electronics and firmware. In this case, it seems there is a problem with the touchscreen software. The printer control mechanism is still working, and so it is still possible to control the printer using Ultimaker Cloud and Ultimaker Connect.

This can usually be easily resolved by following these steps:

  • Power cycle the Ultimaker S3/S5 using the on/off switch. Wait until the printer has completely shut down before turning it on again
  • Update the firmware to the latest stable version

If the problem still persists, please contact support by raising a support request above.

Note: This error was formerly known as ER27.
