Karcher K4.130 Review

I bought the Karcher (K3.86 M) pressure washer from Halfords approx 2 years back. Recently water poured out the bottom of the unit. After reading that other had similar problems I inspected the unit to see what had failed. There is a mechanical clip designed to hold on the "connection" part (This is what you plug the outlet pressure hose to). Anyhow this mechanical clip slots into little groves on what Karchers parts list calls the "housing". There are two sets of groves top and bottom on the housing seemingly allowing the "connection" to be fitted in two orientations. However as the "connection" must protrude from the front only one set of these groves can be used by the clip. On closer inspection the groves are not equal depth and it is reasonable to assume then that only the deeper groves were designed to withstand the pressure the unit generates when in use. However as the "connection" can only be fitted in one orientation the clip can only interface with the shallow groves. My unit failed because the clip sheared through the shallow groves and forced the "connection" off. IMHO these parts were designed for a different outer casing where the "connection" protruded at right angle allowing the clip to interface with the deeper groves. It is hard to believe that a company manufacturing this type of device could make such an error and not understand the cause. Given the number of customers that have written about this problem Karcher seems to have no sense of responsibility to their customers at all. I will not purchase a product from a company with this type of attitude.
