When I switched on my (Karcher KB 9030) pressure washer for the first
time this year there was no pressure and water was gushing out of the
casing. I opened it up and found that the plastic elbow (connecting the
high pressure hose to the compressor) was cracked. So I Googled the part
number, ordered a new part, fitted it. Easy.
I guess the frost must have got to it.
Then after a few minutes, use another leak started, identical to the
first, but on the inlet side this time. No problem it was only a fine
spray and it didn't seem to have any effect on the performance.
Then after about half-an-hour's use bugger me it developed yet another
leak. This time it's a fairly major leak where the second inlet elbow
joins onto the compressor.

The result of the leak is that when the outlet is closed the motor
starts and stops about once a second, and water leaks out of the casing.
When the outlet is open everything seems to work fine.
