Hi, Have an old Sumatran that has been working for years….it is an European 220V version. Lately it started to shut the heater from time to time, by unplugging and plugging again, it came back to work. Finally decided to change the circulation pump together with new filter, to try to fix as I read it could be the pump. Mistakenly after connecting it all, plugged it on without water and started making a noise…. Unplugged as fast as I could (20m away). The spa is no longer working, display doesn’t come on despite of having 220V in the spa input. please advise what to check and look. thanks a lot in advance
