LCD button sticks sometimes....very annoying.

Defective controll board and need to be replaced

Check to see that the menu button has not been permanently depressed, perhaps by the plastic button having been pressed down a little too hard and breaking off internally, jamming the microswitch behind it that it operates. I have encountered this situation many times in other monitors. Worth checking :o) Can sometimes also be cause by foreign materials jamming the button in it's cutout. The microswitch may also have failed. Alternatively, you have a fauly control microprocessor and will need board level service to the monitor

Well, it certainly is related. This is OSD (On Screen Display) for adjustment, activated by those pushbuttons.
Did you try to completely unplug the power cable from the monitor for a minute and then reattaching it?
One of those pushbuttons may have got stuck in a depressed position, check if all of them click properly when pressed; sweet drinks spilled and dried off can make a button stick, and sometimes the plastic itself may develop enough friction for a button to stay in a depressed position.

If all the buttons work freely, the monitor may need professional servicing.

Take a tooth-pick. Jam it between the OK button and the next button. so that the OK button stays permanently depressed. This makes the message go away. After a long time (in my case 30 hours) you will suddenly see the that the controls are unlocked. Magic.

turn the igniton switch to ON, and depress the gas pedal 3 times. watch the light it should go out. sometimes you have to do it, more than once.

unplug everything. press power button continously for one minute.
helps sometimes. sometimes repeating multiple times helps. sometimes repairs the issue for a few months and then finally breaks for good.

It may be the graphics you have loaded on. Are they your own creation? I suggest syncing it with a pre-made template from URC. If not it can be that the sceen has been slightly impacted.

After pressing different buttons and waiting 10 to 15 seconds after turning the power off, I have finally found the solution.
When you have pressed the "Start/Cancel" button to start your wash programme the LCD shows "test".
You must then press the "Start/Cancel" button which will give you the normal temperature and washing time and then importantly you must depress both the "Start/Cancel" button with the "On/Off" button which will give you a different LCD message and then it will automatically resets itself.

ALL THE BEST!

Did you have any lights at all on the panel? I just took off the User Interface as going through the troubleshooting guide I found underneath the control panel led me to that solution.
