If I have understood your post correctly, you have got or purchased a (used?) Karcher K4 pressure washer, you've had to replace the pump and now it makes a screeching noise when switched on?

I gather you've connected the pump correctly and have turned on the water supply? If so, have you considered that it could be the pump at fault or something else?

Amazes me how people join a PC community and the first post is something like the OP

Have you reset it? Tried to reinstall the OS?

I think I've wasted my time with responding, chances are we'll never see the OP again.
