Hi could someone tell me how to solve that nightmare of mine,I`ve got a Karcher 1700 psi, was going hum hum every time I release the trigger but it sound like the pressure is bit low as well,I replaced head.suction valve,and check all the the parts internaland the only part that i didn`t replace is the detegent valve, to me it look perfect ok and the machine is only about 13 months old, never store it with pressure in the unit so what you reckon it could be Please advice
PS. Not even a trace of water leaking from the machine
Hi, I work in the italian factory of Karcher. In my opinion the problem is caused by the breaking of the collector. This is a black component of plastic where is inserted the detergent suction valve and the safety valve. To replace this component you have to go in a repair center Karcher.

You need to check the setting of the unloader. If you've replaced it with a new one it probably didn't come preadjusted to 1700 psi.
