Hi will do (its not turning off) randomly checked yesterday and had 240v to terminals at all times - no heat increase at all, I'm in Australia so we are 240v. have only checked resistance in old unit (19 ohms) will check new unit asap , thanks for your help

Thanks RDspaguy I have 240 terminal to terminal and 240 to ground ....100% not heating... dodgy new unit?

Hi hoping someone can help, my 240v spa stopped heating recently and I checked the heater element (3kw Balboa) and found it was receiving 240v at the element terminals so I figured it was shot and swapped it out with a new one but unfortunately did not fixed and still have a no heating issue . I still have 240v at the terminals. Interestingly I just checked the old units resistance at about 19 ohms so it may have been ok also? .... If the new one measures 240v at the terminals shouldn't it heat?, it appears to have enough flow although I cant measure pressure I can feel decent flow entering the spa
