Thanks both. Ok, though I’m puzzled as to why it appears to work fine for 2 minutes before stopping. This would seem to indicate that it’s not completely broken. Any thoughts as to why it would decide to cut out in such a reproducible manner?

my Hotspring Hottub has developed a fault. When I power it on it goes through its boot up cycle and after 10 seconds the ozone bubbles start and are very vigorous. They continue like this for 2 minutes and then suddenly stop . Everything else appears fine. If I power cycle exactly the same thing happens very repeatedly on timings. All the jets work fine but the temperature slowly drops over time once the bubbles stop. I’m wondering if the heating element is on a thermal cut out? Nothing trips out. any advice would be much appreciated.
