Karchers eat capacitors, especially if used with a coiled extension lead, cheap fix if you know how and folk must get fleeced left right and centre for it.

Skips are full of scrapped washing machines, they've all got one that'll do  my PC is slightly to the right of Genghis
2012 HSE SD4 In Orkney Grey now gone, best car ever.

i have had my Karcher for more years than I can remember and this is the first capacitor that has blown up, the power lead was fully extended as was the lance hose think it more a case of old age than anything else Ex 2010 Freelander2 GS-e Diesel manual Silver owner

Fully extended the cap will,be fine, with a coiled lead it's a different story and the caps don't like it. The smaller 'domestic' models are bad for it.
Look after them and used correctly they do last though
