I have had a Karcher 2.54 for a couple of years. Unfortunately after standing all winter it has now developed a leak where water and pressure is coming out when in use. When very high pressure option is used it seems to be blowing out of everywhere and water leaking from underneath. I admit it has stood in a shed over winter so probably suffered from the freezing temperatures. Is it useless now or is it possible to get it repaired somewhere? I have checked the Karcher website but am concerned about the cost. Probably repair will cost more than a new replacement! Just thought I'd ask anyway.
