Hi JG, welcome to the forum with your first post.
I wonder why people don't give the manual with their machine when they sell it, it would certainly help the purchaser.
I've looked up that code for you. There are a quite a few error codes, including yours, which give this same solution.
You can reset by turning the speed selector to Open Lid and then to Closed Lid. Unfortunately no-one seems to want us to know what the error actually is.
Happy cooking and not too many error codes I hope. Please do let us know how things are going, what you cook etc and perhaps hop over to the Introduce Yourself section on the home page and tell us a little bit about yourself.
