Question about Karcher Garden
This can be a problem with the pump unit. Actually the collector to be more precise. Also, the pump itself. Either may develop a hairline crack and allow pressure to seep out, and tells the pressure switch that it has lost pressure... so it comes back on etcetcetc.
The only repair is to take it to a Karcher dealer or send it in under their rapid exchange plan.
They will not sell parts to Joe Repairman because of liability concerns.

A seal inside the pump has blown. The basic repair cost is $100 including parts
Just had my own do this! Unfortiunately only Karcher have the bits to fix it and would not sell me any parts, so I had to let them fix it. They did a full service and it now works lkike new, so I have no complaints.
Thanks for using fixya

Above links are for the repair manuals for your unit.
A "chattering" pressure washer pump can be caused by many things. You could have a bent or damaged inlet line, or the water supply might be too low. Fixing these is simple, but checking on the water supply is critical. Never let the water supply run low for any extended period of time. Other causes of a chattering pump include water that is too hot, you may have air in the pump system or a stuck float valve. A power washer pump that is vibrating, but not chattering could be the result of air in the system or debris stuck in the valves. Catching these pressure washer problems early and knowing what causes them will save you a trip to the repair shop, especially when it comes to the low-water issue.
Above are some troubleshooting links to help.
