emerald 699 classic

[thearm]

Good morning,
I am getting an E8 error code on my 2005 emerald 699 classic. Does anyone happen to know what that is calling out?
I have had the tub 14 years with little to no trouble and seemed to misplaced the manual with the codes in it.
Many thanks for any help.

Is it heating OK? Does it stay at the set temp?

Yes it is heating fine. Runs ok on low pump setting but when you turn on high it runs for about 7-8 mins and turns off showing E8 code.
