I've fixed the odd one over the years, common problems are from not using proper glass detergent . Thus dish soap congeals in the hose. Pinched lines, car polish in the jets etc. I would try disconnecting the piping at the pump and jet. then test the line for blockages working your way along. Either with a small amount of psi air pressure. Try using hot water from a garden weed sprayer, or even a large CC sized hyperdermic syringe without the needle. Inspect any barbed joints and tees for obstruction. The pump itself might be on its way out...
