I think ours has had it. It just stopped while I was using it today and the body of it felt quite hot. I left it a few minutes in case it had some sort of thermal cutout but it still won't work. When you pull the trigger, sometimes there is a hum from the unit and sometimes there isn't but the pump doesn't run at all. (or is it the motor that runs the pump?)
Before I bin it, is there anything obvious I could or should check?
And if I have to bite the bullet and buy a new one is it best to stick to a well known brand like Karcher?
