After replacing the pump motor and heater last year we have had problems with our great lakes sunlighter spa with em104 controller. It runs in filtering mode all the time (and heater works with thermostat) or it will be off and runs on high only when the heater turns on. So to enjoy the spa you have to have the heater running. And to keep the spa heated it has to run continously or turn to high every time the heater turn on. The obvious timers and contactors have been checked and cannot find the problem. Any possible solutions to get my tub running properly?

Problem solved. Motor wired improperly.
