My dishwasher will just stop after 5 min and the display will say ER and all the red lights around the display will flash. I put some vinigar in it and that did not seem to help. Also the light will flash and say HI/Low temp. It also seems only to accept normal wash and no other cycles. This washer is just over one year old ( about 1 1/2) in use . It is the professional series. Thanks for any help.

Mine did the same thing but is a different model. Did you ever find out what caused yours
I honestly could not tell you for certain what the cause of this problem is, but from what I hear it’s usually the board itself that is failing on these Frigidaire models.
