I have a 520M power washer. The hand gun is leaking when i switch it on.What might be wrong with it?

After the heavy frost when I used the power washer the hand gun leaked water. Is it possible to repair the gun? There are 4 star screws and others that look like screws. How do i remove these to see if a part is damaged?

  • I have the same problem so I bought a new gun and what do you know it happened again but this time it happened as soon as i put the new one in.and i got it off ebay but they will not replace it they said it was my fault as it was the way I connected the hose to it .something to do with the flow of water and the valve in the connecter.anyway I opened it up to find it was just a 0 ring so I replaced it but now the hole gun handle just pops open every time \i try it.So it's a new gun again and hope 3rd time lucky.
