[Solved] Karcher WV2 window washer - engine not working and blinking diode.

Good morning,
I see on the forum that I'm not the only one who had a problem with the Karcher WV2 window washer, and I was like that. After washing the windows, the dried equipment went into the box. Approx. 2 months later when it was removed, it turned out that it does not work and the power LED flashes quickly. The equipment is under warranty, so I went to the service. The service technician used a screwdriver through the hole under the water tank to spin the impeller and everything started.

It turns out that too much rotor resistance puts the electronics into emergency mode. He also gave me advice that I would like to pass on. Don't just leave the washer to dry after cleaning the windows. Residual dirty water can collect at the bottom and mechanically block the impeller. The gentleman from the service ordered the body itself to be turned on for a few minutes, so that the "guts" would cool down, and then it was necessary to charge it. The battery emits heat during charging and it dries out even better from the inside. As a result, it will avoid such failures. I hope I helped a few people.

You saved me from being lynched by my wife. We didn't even know that this washer was disassembling and there was good access to the tank and the impeller Thanks!

Thanks to your hint it worked. It works . thanks a lot. Regards

Thank you. The method also works in the WV5 washer.

Thanks you are great ? I already wanted to start it, it was enough to tinker with the hole - my wife is happy ?
