Karcher wv2 window vac won't charge. It is plugged in correctly& connected to mains.

Do u need charge battery may be a fuse in plug or change power supply

Check the hoses for clogs due carpet fibers.

Karcher wv2 won't charge.

Could be a defective switch, or it is locked because a threshold is reached, like reservoir is full.

But check while it is charging, because the manual says:

If you contact one of the Karcher Centers ( details are on Karcher.co.uk website) they may be able to help.

Have you tried to take it all apart just a small bit of rubbish will stop it from working.

Take it apart and see what is stopping it (the motor) from turning .

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

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.
