How to Repair a Karcher Electric Pressure Washer

How to Repair a Karcher Electric Pressure Washer. Repairing commonly repairable things on your Karcher electric pressure washer yourself is like putting money in the bank. A technician at a repair shop can cost you a premium hourly rate, to say nothing of the markup cost on parts. No matter, if it’s a simple rubber gasket on the pressure hose that needs to be replaced or a spring in a spray gun, save yourself money by buying the parts and doing the work yourself.
