you have a faulty air pressure switch problem, remove the top find the pressure switch round thing with wires and a plastic pipe attached, remove the plastic pipe from the switch end now blow down the pipe if you go red pipe still blocked follow the pipes run and locate the other end. (prepare for spillage old towel )remove the pipe end and clear out the small hole,(this hole when clear operates the air switch as the pressure in the pipe rises )now reassemble both ends of the pipe and allow machine to fill
