Problems with my Karcher k2. It just stopped dead. On removing all the casing i was able to move the fan at the rear of the motor and it started up, but on stopping i had to move the fan manually for it to start again . are there brushes on the motor that are worn, if so where can i download detailed drawings. Regards john.

You tube, karcher k2 900 take apart, This is the easiest way to do it,

have you removed all stickers?

Check to be sure that the GFI on the plug is not tripped. If that is ok, try turning the motor a little - use a screwdriver, stick it through the fan housing and move the fan 90 degrees. Then try turning it on. If it starts, the problem is with the motor starting to go bad.

If you have a Karcher then you should always post your machines barcode.

Because you have the low pressure and pulse this will be the valve block. Your machine has 3 piston and each has 2 valves (inlet and outlet). Because you dont have the barcode, i cant be sure if you will buy a valve kit of 6 valves or a pre-assembled manifold block.

it could be this machine and spares :

The karcher barcode is on a silver sticker and is usually 15 digits long. Example 156987400000123 is actually model 1.569-874.0 and serial number 00123....

Check the fuse on the unit. Since this is a electrical unit, it may have also tripped your main breaker on your power source. If using an extension cord, try to use a larger one (size of wire) and shortest as possible. For more info go to www.karcher/co.uk/images/manuals/outdoor/k2 (Troubleshooting problems) .... Good luck.

s this sound like a noisey fan . if older model i would replace the fan motor . / other problem could be the fan blade has moved on the motor shaft . so just replace the fan balde .. mm

the motor has sized up on you free it off if you can giveing it a splosh of wd40 in the bearings may help

wot like a buzzing noise if so try and turn the fan at the rear of the motor if you can do this it is more than likley the capacitor

Good day,
Assuming the lights are working, and you hear it running,
Check the most common problems first.
1. Open the freezer door and see if you hear the fan motor running. If not remove the rear panel in the freezer panel and inspect motor.

2. Most common, another fan motor motor in the bottom rear behind the rear cover was jammed while moving. Remove rear cover, inspect, and repair.

3. Check for wire damage elsewhere in the bottom area where that motor is located.

4. Make sure controls are on and set to normal.

if you contact Karcher they will tell you where your nearest supplier is located. try this link.
