Karcher K2.26... | Answered 3 days ago | 674 views

Had the same problem and it turned out to be an obstruction in the nozzle and I mean a small obstruction, it looked like an ant leg. I pushed a 1mm drill bit through and now it works fine.

Maybe press regulator was reset before the unloaded was installed and needs to be set at lowest and then increased as needed.

Karcher WV50... | Answered on Feb 27, 2019 | 257 views

This happened to my FC5 too. I found that the detergent outlet within the suction head was clogged up. This is the receptacle for the brass nozzle you can see when detaching the suction head (by pressing the grey button and gently pulling on the yellow "cover" at the top of the cleaning head - Figures 16.1 and 16.2 in the manual). To check it is indeed clogged, put a few drops of water in it - they won't drain out. To purge it I used the jet from a handheld steam cleaner, and I also used the steam jet to clean the suction slots. Be very careful not to scald yourself, wear gloves, and when cleaning just pulse the jet so as not to risk damaging the plastic parts.

The WV does not have a serial number - Please input "000000" Into the "Serial Number" box. Please note - the registration is not validation of your warranty. Your proof of purchase (receipt) will need to be provided, should you have and problems with your machine.

We hope this helps, If we can be of any further help, please do not hesitate to contact us.

Possibly. The amount of "badge engineering" going on, its possible they are the same machine with a different name sticker. You would need to have both to confirm.

Probably water ingress in the motor or wiring.

The trigger valve either needs new o rings or possibly just to be snugged up a bit.
