My hot tub controller (Balboa VL-7000 Series according to the tub's instruction manual) has a two hour filter cycle every 12 hours. I recently cut the power to the tub to reset the time of the 12 hour cycle. It starts the cycle 6 minutes after power on.
Since then the high/low pump that is in the low flow mode for the filter cycle stays on in low flow mode all the time.
Normal operation has the low flow on if the tub is heating in Standard or Economy (heats only during the filter cycle) mode or during the two hour filter cycle in Sleep mode.
If turned on at other times it may run in low flow for a minute before shutting off.
I have cut the power for several hours hoping it would boot up and cure the problem, but no luck.
Any thoughts or suggestions?
