My karcher hds 745 has started blowing fuses. it switches on the power light comes on and it makes a buzzing noise for about five seconds and then blows the mains 13amp fuse. i have replaced it twice but the same happens every time. the power lead is fine

Question edited for clarity. 'Karcher not 'Kracher', add (what it is).
Question moved from Washing Machines category.

It sounds like the contactor has failed internally. This often happens that the internal contacts arc and burn away. The click is the electromagnet still working. Take it off and test it, or leave it on and test the output for continuity once energized.

It is not a known issue.

Not sure what the 'o.eltro' means? There is help in the link and the service manual for a different series of HDS washers. You could also contact Karcher direct.

My Loewe Aconda 81 HDR TV will not turn on. When I press the power button the green light comes on but the red light stays on with it and after a few seconds the green light goes out and the red light stays on. Any help please.

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.

Fulltech.

G-day Mate.

Did you check if the igniters? they may be cloged up with ****. Unscrew the Sight glass on top of the boiler and run the machine (in cold or hot mode, doesn't matter, as the igniters are running all the time) and see if there are working, you should take them out anyway and give them a wipe with a rag as general maintenance item, and when you put them back in there should be about 5mm gap between them.


Less common reasons for the boiler to not work
- Faulty fuel solenoid valve, (You should hear a click sound about 5 - 10 seconds after you pull the trigger)
- Dirty fuel filter,


Take a look at those simple things and let me know if its any of these.

I have a Karcher HDS 750 1989 Year model

This machine just keeps going, it's had a fairly tough life but it has stood up to it all,

i hadent spent anything on it until about 6 months ago when i purchased a new fuel pump for it as the old was wasn't pushing 170PSI to the Disiel injector it had slowly droped 70psi, and it doesn't create a hotter burn in the boiler, but still very good for a 19yr old pump,

other than that thats all it's needed, it's still going strong to date
Very robust machine.

Cheers Matt.

When there's a loud buzz like that, it does not heat, and does not blow the fuse, it is usually a defective magnetron. Did it sound something like someone making a "gurgling" sound into a coffee cup? I think this has a a one-year warranty, with n five-year warranty covering the magnetron.
