    solid red light on pump 2 dos when first plug in

    Hi please help i don't understand when i first plug in the power cord only into the DOS the led on pump 1 flashes between red and sometimes green while pump 2 flashes red only then plug in apex and pump 1 light goes solid orange and primes with blue led. Pump 2 goes solid red and primes fine but no blue led and after calibration which both are good 40ml led stays the same solid red on pump 2 and pump 1 goes back to solid red as well. If i hit prime on pump 1 Blue led but not on pump 2 it just dims the red on led. Funny thing is i think everything is working but i don't want to leave it just in case.. Neptune support says it might be the PCB or motor but didn't specify.
    thanks in advance... any help would be appreciated.

    So i pulled it apart and cleaned board with isopropyl and discovered tubing that sends led signal wasn't right. tried to fix as good as i could and now pump 2 is changing to blue well purple when i hit the button and pump 1 is flickering through colors at random but mostly orange green... but is still red on start up on pump 2.. its the pcb which is the board but I'm thinking its just the leds.
