Did anyone manage to figure this out, I am now having the same problem Balboa VSC500z control board, it has been working as expected up until recently, now the recirculating pump stays on permanently. In Prime mode the pump stays off, indicating the relay is fine. The heater seems to be working fine, it heats to the correct temperature, then the heater shuts off (led light on topside goes off, and temp remain stables). It makes no difference which filter program is set (F2 - F8). Pressing the Jets button only cycles through, low speed on the pump(recirculating) and high speed(massage), previously the pump would also switch off. I checked the wiring on the motor, if I reverse the the pump speed is reversed also (no surprise).
