To me this problem sounds like there is something wrong with the pump.
I think its better to buy another Karcher machine and get the 12 month warranty. As with old pressure washers you could spend money on certain parts to fix the machine but a few weeks/months down the line a different part of the machine could break and then you end up having to buy a new machine anyway.

Also being 15 years old you would have to check to see if parts are still made for the machine. This is because once Karcher discontinues a machine parts for that machine are manufactured for 10 years from that discontinue date.

Most of the time it is the GFCI on the end of the plug that goes bad. If it were me I would cut off the GFCI and wire in a standard 120v plug. If it still doesn't work after that then there is a good chance that something electric internally has gone wrong which isn't going to be worth repairing.

Everytime i switch on my 6.80 pressure washer the fuse blows on the machine


This sounds like the bypass (unloader) valve is sticking and the internal switch it activates is being held in a half open position. This will blow a fuse. It could also be loose wiring inside. If you ran it with an extension cord you may have weakened the fuse. Sorry, I cannot find a schematic anywhere. I think it is European, correct?

Dear dumbelldaveb,
Having a 13A fuse I am concluding that the machine is single phase. Most probably you have a faulty capacitor. Check the capacitor and if you find it expanded and leaking...then you must change it with a new one. If you see the capacitor is normal just the same it could be shorted. So change the capacitor with a new one and try to start the machine WITHOUT LOAD. Which means no water inlet and no gun attached. Doing this you can also remove temporarly the micro switches. If the motor still hums, then most probably there is a fault in the electric motor.
Now if you find out that the fault is the capacitor (which in my opinion it is the case)...you must see why the capacitor broke. If when using the machine and the gun is closed, the machine starts on and off on its own,...this will damage the capacitor. This on and off fault could come from a leaking gun. Or a leak from the seals. Whatever....the machine must not be left going ON and Off when the gun is closed. This ON and OFF could be due to faulty micro switches and control valves.
I am very sorry to mention a lot of things, but I hope as in many cases,..the changing of the capacitor will solve the problem. I wish to add that the electrical lead wire must be checked. On many occasions I found that the electrical lead wire from the plug to the machine was damaged and shorted, ..due to pulling, wear and tear.
Regards,
Fulltech.

you have an electrical short in the motor windings. you'll have to either replace the motor or buy another washer. also check to see if the motor isn't locked up with a piece of trash. to do that you'll have to dissassemble housing until you get to the motor. it should turn easily by hand. if so you have a short.

Contact Brother

To the left on the above site is a software download page.

If you need further help.. email brother...they will tell you how to fix this. Takes them a day or so to answer.

Sounds like the technician may have put in a wrong fuse himself. Hoping it was a Brother authorized dealer.
