How do i clean out the hose on a lux classic upright

take it apart and clean all vents,replace hepa or all filters,clean hose and brush,it is clogged up

The output filter on that unit is HEPA and traps all particles. You need to clean or replace that filter because the airflow cannot leave through it and it wont develop suction.

check all filters are clean, if ok check for blockages in pipes, it will stop if the motor overheat then restart when it cools down click on the link beloe to download manual if you don't av one,,

The real clue seems to be the brush is not turning, a bad belt is possible or a blockage at that head, if you cannot get the brush moving the rest does not matter.

green light button has stopped working for carrpet cleaning

Could be the board in the handle but I found that a lot of the times the contacts where the handle meets the hose just need to be cleaned. It could also be a clogged hose but I'd say it's one of the other two.

Set Ready Tools Dial to the Hose
Attachments Setting. This will allow spray and
suction from the hose.
Set Custom Clean Dial for Heavy Traffic, Normal
Clean, Light Clean, or Rinse, as desired
Attach the cleaning tool to the end of the hose.
Plug in and turn on the Power Switch and Heater
(if desired).
Clean by pressing the trigger to spray solution
onto the area to be cleaned. Slowly move the tool
back and forth over the soiled surface. Release
the trigger to suction soiled water. Continue to
clean in the area, working in small sections, until
no more dirt can be removed. Rinse (optional)
and suction as needed.

Check & replace any filters that are fitted to machine.
Replace bag with new,
Clear hose of any foriegn items & check floor tool for blockages.
