i have a hilka jet power washer 145 psi was washing great good pressure although i think its an old one;then it lost all pressure just working on hose pressure any one with any ideas; im an engineer in a differant field ?.
Presumably the motor is still running....these machines need back pressure in the lance to make them work, also there are valves in the power head that the motor drives that could be faulty....easy enough to see how they work when you take them to bits, but getting parts is another issue!
