Mad Mike

Hi guys, I was about to jump in for a bit if chill time. Display said gecko initialising then came up with above message. Water cold and nothing running. Tried power off for a few minutes but same. Pulled out all of the coloured plucks and reseated them. Same. 😡😡😡 Haven’t used it for a couple of weeks anyone got any ideas? installed December 2016 so not exactly old. Used about 20 times a year
