Question about Karcher Garden
I have a Karcher K5.55M The motor pulses when switched on but not spraying and only sprays at approx 1/2 pressure when the trigger is pressed. It is only about 2 years old and has not been used very much or hard worked.
In the video link above, at 7 minutes,.. through to 7 minutes 8 seconds,.. the guy talks about a "minute crack in the cylinder head". He actually means to say "minute crack in the control head". This minute crack is the main reason for this common problem: the pulsating and some loss in pressure on a wide range of Karcher waterblasters.
I got a replacement control head from my local Karcher dealer for NZ$50 that fixed the problem,.. for now :-( The below picture has two red ovals around the cracks in the control head that are very hard to see. If Karcher made this control head from an aluminium casting, their product range would be a LOT better.
