vortec pump error flashing red light

[larryfl1]

i have experienced a new issue not sure why...

i have the pump1 go into nutrient transport mode 8-9am
pump 2 is slave/opposite

then at 9am forward i go to normal ecosmart mode not nutrient mode..

the main pump changes fine...

but the slave goes into red blinking error mode...

this has happened 2 days in a row...

any ideas?
