[Solved] KARCHER K7 Premium Full Control Plus: Gun blocked, faulty pressure

Hello,
I have a problem with the gun on my KARCHER K7 premium full control plus washer.
The gun paired correctly and for the first day everything worked properly,
Now (after a few days) the gun has "locked" in one mode, when changing the wash mode on the lance - there is no change on the display.
I can change the water pressure but it works "in reverse" i.e., when pressing the "-" the pressure increases, reaching a maximum when the minimum value is on the display.
Re-pressurising the gun doesn't help - I have no way of changing the mode.
Anyone have any ideas on how to fix this? I would appreciate any tips
.

Hello

Unfortunately I have the same problem as you with the Gun (locked as if in the position "Mix and despite the rotation of the lance does not respond to other programs, it is only possible to adjust the pressure in three steps only for the Mix program). My Question if you were able to solve the problem and how, if possible please reply.

I have sent the equipment back to the service centre, I am waiting for their reaction

If you know anything please let me know and thank you in advance. Best regards

Hello,
unfortunately the same problem has occurred in my K7 today.

Hello
With me so far the problem has died . I switched it off from the power supply and the next day tried again and it worked. I paired it again by holding the lance next to the karcher to keep the distance between them as short as possible after bluetooth communication and it worked. But I am still waiting to hear back from the gentleman who sent the equipment to the service. I wonder what they told him. Greetings

I have the same problem with my lance today , that is it works in reverse plus is minus and minus is plus and it works in one mode . And it happened from the moment my child turned off the water in my tap and I pressed the gun . The device started slinging intermittently and the gun was just left in this "MIX" mode . I have already experienced this after buying the device, it was working fine and then suddenly it went into "MIX" mode, I took the device to a service centre and they replaced it with a new gun. But as I wrote at the beginning with the new gun I have the same problem . But now that I see that this blockage was caused by turning the tap on and off again , it seems to me that maybe some impurities flew into the gun and it got a bit stuck . I also don't know I would like to know what the problem is . In any case, if they are replacing the spray gun with a new one, it means that they don't know what the problem is.

Hello
Propo of the mix programme lock on the lance - one thing is for sure that it triggers when there is no water ( at my place the water hose broke down for a while) . However, I am still waiting for a reply from the gentleman who sent the equipment for service. I am curious to know what the service found. In my case, the problem disappeared the next day when I steamed the lances with the washer from scratch.

The equipment has returned from service. According to the service report, the pressure switch has definitely been replaced - No. 6630-839.3
There is also the following information:
Unable to pair the appliance with the gun - the aforementioned component has been replaced with a new one.
However, I do not know which component this is about - the gun and lance do not appear to have been replaced - they have scuffs from use.
In any case, the defect has been rectified and the unit is working properly. I suspect that it is the above-mentioned pressure switch.

Hello
You have already received the equipment from the repair service and of course what was their diagnosis. Greetings
