Looking at the photos that you have supplied, it indicates that the filters are blocked. The easiest way to test for this is to:
- remove all filters and shut the filter door (may require turning the filter locking bar to allow the door to close correctly)
- run the machine and see if the error goes away
- if it does then put the filters back into the extractor one at a time and run the extractor in each case
- the error will reappear with the blocked filter.
It is also worth noting that you have a high run target speed set this should be reduced prior to testing and afterwards set to the minimum level required to extract the fume.
If the filters are more than one year old they should be replaced as a matter of course.
