no pressure

If my jetted tub's motor sounds like it's running, i.e. the humming sound it makes, but no water is shooting out of the jets, is something not turning in the system or could the intake screen be clogged?

Air lock?

How long have you let the pump run with the tub full? Sometimes the plumbing can hold air which becomes trapped on the suction side of the pump. With the pump off, you can try putting a clean plunger over one of the jets and forcing water into the pump. When you are finished turn the pump back on and let it try to pick up prime for a couple of minutes. If this doesn't work it may be a sheared pump impellar.
