Hi ,

Im hoping some one can help with this problem the bag full light wont come on unless you completely block the end of the wand with your hand and then theirs a second or two delay.
I've had partial blockages bags full to bursting and it still doesn't come on.
How does this work i cant find any type of pressure sensor in the bag compartment . So does it work from the hall effect sensor rather like the height control,
I was hoping to see a pot on the main pcb that i could adjust but its all electronic ?

It depends on the age of the machine. Early ones had an adjustable screw on the top PCB. On later ones there is a tool to set them (that seldom works), however they tend not to come on unless they are pretty much completely blocked anyway, otherwise they would come on with a partially full bag.

Yes ive seen the screw on the older machines this unfortunately is the newer type with no screw. I had a feeling it would be IC controlled.

Oh well thanks for coming back.

They all take around a second or two for the bag light to come on anyway, they don't come on instantly when you block the hose suction with your hand.
