If you’re experiencing any issues with your Durr VSA 300 S, see our troubleshooting tips below or call 0800 298 5003 and press option 3 for free technical engineering advice.

One of the key issues is when a Durr VSA 300 S overheats during lengthy procedures. This can be caused by the following things:

  • Blocked pipework or filters (don’t forget the in-line yellow filter by the inlet to the pump)
  • Incorrect maintenance – ensure air is allowed through when water is flushed through, use the Durr products properly (Orotol and MD555)
  • Overdue service
  • Parts of debris on the main impellor – covered by overhaul
  • Cooling fan not operating correctly
  • Damaged machine – main stem of alignment
          •  
          • The list above provides some insight into a few factors that may be influencing your Durr VSA 300 S from running smoothly, however you may find this to be irrelevant of the actual issue and thereby require further technical support. The table below represents a list of errors, possible causes and possible solutions for each one.
