I ahve a Kopec 650 TI about 3 1/2 seasons old.  Won't turn on to start this season.  Green light is on, pump is working fine, good flow.  However the red light that indicates low flow does NOT come on when the pump is off.  In years past it always comes on when the pump is off.  Could it be a bad flow switch?? It is in "time clock" mode

Thank you for writing. That could just be a bad bulb. Not sure why the heater isn't coming on. I always like people to call Mr. Kopec and to have him involved. He designed the heater and he takes it personally if they don't work and will do anything he can to make it right. the factory number is: 866 917 8998.
