First is to try the reset
Unplug for no less than 5 mins
If this does not resolve the issue, please refer to the Tech sheet HERE, especially page 9 to start, then follow steps outlined
This is rather Technical, however, it is the Checklist for the given error/s and much more
I do not suggest these remedies are something you will be able to check yourself... it may require a decent Tech to run the list...
Please understand that not all things can be resolved at home without some closer inspection and intervention. This is the case here, and my best advice is to seek local hands-on inspection and service, it is for a good reason, so please do not shoot the messenger, it is to save you time and money.
Please get back to me if you have any other questions or concerns and I will try help you more.
If you feel that I have helped to answer your questions please remember to rate my performance positively before you leave so that we can close the file as it is the only acknowledgement we receive for our time and experience.
