my triton t80z will not operate?

i have power to the unit but when you press the power button to start it nothing.used 3 times that morning.flow is good ,no blockages,checked the prd not sure how this works.took it off couldn"t blow thru due to small rubber ball in.hasn"t tripped out and is only 6months old.i do get a flickering light on the power button but at a loss.i have wired this in myself .
