Hi,
We just came home from vacation to a cold hot tub. It is showing three small dots in the display. If I remember correctly, that means something about flow. The heater icon is on, but no amp draw on power wires. All pumps work, circu. pump is on. I removed all filters, reset hot tub, but three dots remain and heater is not on. I havn't open cabinet yet, it's to cold, it can wait for this weekend (80 degrees, maybe). Does anyone know where I can get a service manual (not owner manual) and/or a wiring diagram? The warrany on the heater runs out the beginning of May!
Thanks
John
