Hi Alan
Unfortunately, I think you problem is in your control board, I say unfortunately because it is an expensive part. Here is the replacement board.
Part number: AP4026827 
Also, if you have not had or you have not yourself replaced the wax motors in your machine you should (must!!) do so at the same time.
Here is the service manual on your machine (yes it says MAH 3000 but yours is an updated version of that machine.

You will have to decide if you want to try the fix or get a new machine (or even live with it the way it is,if you do replace the wax motors)
Good luck.
