** one day a "Blocked arm" message is comming up **

Is there a specific error code displayed?

Some GE dishwasher models monitor rotation of the spray arm during wash by use of a 'reed' switch on the side of the tub that detects a magnet in the tip of the spray arm passing close by it while rotating. If that arm was not turning (like could be due to insufficient water in the machine, a problem with the wash pump or wash system or physical obstruction of the arm itself) or there was a problem with the motoring system, a blocked wash arm error code might be displayed.

I have also been told that a problem with the door latch switch can also sometimes result in a blocked was arm code displaying. I have no personal experience with that cause though but wouldn't hurt to be tested during service.

You can find owner's manual resources in the 'Home Service' section of my web site linked below. It won't likely help with service problems though.
