Yellow Karcher K2 Car Home Pressure Power Washer Trigger Gun Replacement C Clip

Product Information

The labelling on the lance (3 - Hard, 2 - Medium, 1 - Soft and Mix - for detergent application) relate to use with a Karcher G145 Q Power Control Gun as the gun will display the pressure setting in relation to the labelling. The process of dismantling and reassembling the pump has been clearly explained in this video. If you know your way around appliances and tools, you may not need an electrician to do this. 4. Leakage from Piston Seals in Undamaged Pump

The outlet seal is at the connection between the pump and the high-pressure washer hose that pushes water to the trigger wand. This point of attachment is similar to that of the inlet connection in structure, complete with couplings and outlet seals. Then, disassemble the pump further to separate the valves, upper oil seals, injector cage, spring, and injector valve. If you find your Karcher K4 leaking from bottom or connection parts, here’s a video to show you how to pull out the pump before disassembling it. Slide and pull out the inlet cover with the inlet seals to find the red inlet valve in the slot. You can remove this inlet valve with the help of tweezers – and place a new valve there before reassembling the cover and the machine. If your pressure washer has an undamaged pump and inlet/outlet seals, the piston seals might be damaged. Karcher pressure washers have a positive displacement pump with pistons to pressure and draw the incoming water supply and force it out through the cleaning nozzle. The problem of water leaking from the spray gun can be easily fixed by ensuring that the connection between the hose and the gun is tight and secure. For that, press or screw the gun firmly to the hose.I asked a question on here about 3 or 4 months ago, as having not used my pressure washer for some months it had started leaking. It made a rattling noise when I moved it. It was suggested the fault might be the O Rings. I have a Karcher extension hose between the front of the unit and the pressure gun. That has seized onto the pressure washer, and however hard i try i cannot shift it. As a result I hadn't got round to stripping the washer.

If you find your Karcher pressure washer leaking, it’s usually because some part of the device is worn out or loose. You may choose to repair the part, but in most cases, changing it is a better option to breathe new life into your pressure washer. FAQ a) Why is your Karcher pressure washer leaking oil? But here’s a word of warning! If you’re not experienced in handling hardware or don’t feel confident, don’t wing it. If your Karcher device is still within its warranty period, it’s better to take advantage of the company’s customer support system. A leaking pump indicates that internal piston seals will have to be changed. For that, you need to take the pump assembly out and inspect the pistons and the O-rings. When the pressure washer runs and allows the water in without spraying water, the water heats up. But if the water becomes extremely hot, the thermal release valve can get damaged, causing leakage and pressure loss. How to Fix – If there’s water in your washer’s engine oil, the faulty oil seal will need to be changed. For that, you must disassemble the pump assembly to detach the pump from the piston housing.The pump and switch assembly are clamped to the motor assembly with screws that need to be undone. You will then have to remove the inlet and outlet, held in place with metal forks. Leakage can also take place because the press fit/screws are not working correctly. Or, the O-ring of the hose might be broken or damaged. How to Fix – Also, detach the chemical injection tube, the metal clamping plate, and the switch assembly to free the pump from the loosened piston assembly. You can pull apart the manifold and the lower part of the pump.
