It's been happening 1.5 wks

Do you have old part motor for my unit?

I would pay special attention to the airline elbow and the venturi nozzle which opens and inside is a white "pre nozzle" and debris or calcium deposits on either will greatly affect performance. I would soak both in 50/50 vinegar and hot water over night. If the pump runs and moves water I would not consider this to be the issue. Both models of 9002 pump are available (pre 2009- 0800.040 and current version 1073.008), if you need one I would confirm the current model by the sticker on the pump and get the same one.
