If you notice speed 4 reverting to speed 3 after approximately 6
minutes:
This is not a fault. Regulations issued by the European Commission in
January 2015 dictate that internal motor extractors with a maximum air
capacity higher than 650m³/h must be equipped with a timer device
that automatically switches the speed from ‘4th’, or intensive, to 3rd
after 6 minutes of operation.
If the remote control is (temporarily) responding incorrectly or not
at all:
If the power supply to the extractor is cut and then restored, the
appliance will run an approximately 15 second diagnostic programme.
During this time the controls may not function properly.
If any of the potential resolutions in this guide do not resolve your
issue, please contact CDA Customer Care using the contact details
