water running through washer but no pressure is it cheaper to repair or renew with new

Arthur, April 2011

I am having the same problem. I hear a buzzing from the engine but the pressure doesnt come on then after a little while the buzzing noise stops as well. Before it would only work for a few minutes then go off and I would have to wait at least 30 mins or more to get a few more minutes use out of it. But now I dont even get that much out of it.

So basically at the moment its not use at all. I am happy to give a go to fix it but I dont know anything about motor so does anyone have any guidance on what to try and how to do it.

Cheers

Karcher will tell you to buy a new one unless you can fix it yourself, so why not try to fix it yourself first?
espares has all the karcher prts. they are simple machines, but you will need a T27 star key (or buy the set) and a set of allen keys (large) though if you have a full set of star keys they will undo allen type too.
On the electric machines, the water p[ressure through the hose controils a switch to the soap feed.. when you switch to a high pessure mode, this then clicks the switch via a toggle mechanism.. if the toggle is sticky, the pressure pump wont be triggered. use baby oil once freed, then lithium grease
