If the red LED (FILTER CLOGGED) is illuminated, it could be due to several reasons. First, the pressure setting might be incorrect; ensure you set the correct threshold value. Second, check if compressed air is available and connect or repair the compressed air supply if needed. Lastly, a clogged filter cartridge could be the culprit, in which case you should replace it.
