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.
| Error | Possible Cause | Solution |
|---|---|---|
| Device not starting | – No mains voltage – Undervoltage | – Check mains supply voltage* – Check fuses and replace if necessary* – Measure the supply voltage (call electrician if unsure)* |
| Faulty motor | – Problem with rotational speed sensor | – Check hall sensor is correctly seated* – Check plug connections of sensor cable* – Check magnets in fan wheel* |
| Unusual noise | – Solid particles in turbine chamber | – Disassemble unit to clean both housing and turbine* |
| Leak from exhaust air connection | – Membrane valve blocked – Foam in turbine, due to improper cleaning – Condensate build-up in exhaust air line – Waste water line potentially blocked | – Check valve at waste water connection, clean or replace* – Use non-foaming cleaning and disinfectant products – Check pipe system, don’t let it over-cool* – Clean water line* |
| Low suction performance | – Coarse filter blockage – Suction line leak – Soiling which has caused mechanical sluggishness | – Clean filter at intake connection – Check leak-tightness* – Disassemble to clean turbine* |
