Sorry about that. This is an air bubble that is blocking the flow of the CBD, and there are three ways to clear it:

[PAUSE 10 SECONDS]

1. Give it several hard shakes downwards towards the nozzle. Test it.

[PAUSE 10 SECONDS]

2. Do the same as above, but knock it against a hard surface several times. Test it.

[PAUSE 10 SECONDS]

[FOR ABSORB PLUS ONLY]

3. If the last two methods don’t work, pull the white inner cartridge gently out from the outer see through plastic case. Below the nozzle you will see a spring and below that, on the white cylinder, you can see a seam which is the join for the nozzle (which acts as a cap) on the cartridge. Gently tease this off, you may need to use a blunt knife or screwdriver just to tease it off. Once off the air bubble will have dispersed. Replace the cap/nozzle and away you go.
