I have an Aquatronic 2 ultra that up until a week ago was working fine, it now runs lukewarm at the previous setting used and has to be turned all the way round to the hottest setting to get any heat which reduces the flow rate to a trickle, what is the problem?

Mine is doing exactly the same. I think that it has moved to default setting on low power . If I can fix it is will let you know
