ajfs67 Posted December 31, 2020 Report Share Posted December 31, 2020 Hi I have a sundance maxxus 880 and pump 1 stays on, it ended up heating the spa to 108° until i noticed and turned off the breaker. On the display it says the pump is off but It still stays on. I have not done anything new to the spa lately and its been running fine the past few months. Thanks for your help.

CanadianSpaTech Posted December 31, 2020 Report Share Posted December 31, 2020 Check your filter cycle duration setting. If it has a circulation pump for heating and filtering then you might have a stuck or burnt out relay on the circuit board Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted December 31, 2020 Report Share Posted December 31, 2020 It's a stuck relay. An electronics repair guy can replace that. 1 Quote Link to comment Share on other sites More sharing options...
