Why does the green light stay on when my window vac is turned off


It never did this before. I would assume that light indicates the battery is fully charged.

It keeps dying even after being charged.


You need a new battery. I could describe how to rebuild the old one if you are so inclined to do that type of thing. It would save you some money over buying a new one. It looks like it is a specialized piece of cleaning equipment and buying a replacement battery would be fairly expensive.

Where's the serial number on the karcher WV window vacuum


Hi. I've just bought the karcher window vac wv50 & am having the same problem finding the serial No. I presume you want to register your product for the guarantee to be valid. I went online Karcher.co.uk & registered mine. You will note that when doing so it does not ask for a serial number but a model No. This is found on the side of box you got the item in (mine is just above the barcode) & it reads something like; 1.633-113.0. Hope you still have the box!

Can't switch Karcher window vac off


I had the same problem and I let the battery run down to stop it cycling on and off. My husband investigated it and found that there is a fault with the on board battery charge sensing circuit. (when the charge is about 10 to 15 % remaining the onboard ic controller cycles the unit on and off, irrespective of the switch. He checked it by cutting wires to the switch and it still cycled off and on so the switch was not faulty.
He put it all back together and said to charge it before it gets too low. If it cycles on and off it probably needs a re charge at that point.
Unfortunately there is no battery level indicator on the tool and nothing to suggest in the manual of what may happen when battery is flattening.
I am taking this up with Karcher as I only used it three times so far and it it was not a cheap gadget. Hope this helps

Cordless vac won't hold a charge


Like all batteries after a while they go bad/will not hold a charge. especially the kind that is always plugged in/always charging, like electric shavers, cordless vac and so on.
get a new battery

thanks for rating
