If you purchased your machine, used, how pure was the water delivery into the unit? Because of the intense heat and pressures the machine must be fed softened water. The head groups are precision machined and the resulting tolerances are so close that minerals which enter the system could solidify and clog up the network of journals. My suggestion, based on our experience, would be to remove the plumbing from the head group and visually inspect for mineral build-up.
