Hi , our extraction unit has three flashing LEDs when it is turned on. The unit sounds fine , but it fails to extract fumes and smoke. The filters were replaced around 4 months ago and are not blocked. I removed the rear outlet pipe from the the VL-200 and there didn't seem to be a great deal of suction ( if any) .
Any ideas?

Thank you for the reply. I will take a look at the fuses - where about are they located in the unit?

Behind the cover on the left hand side. You will need a 3mm allen key to remove it.
Thank you Martin. I will take a look tomorrow , is there anything else I should look for? The diagnostic notes are a little vague.
