Please help me solve this issue. I have 2x MP40Ws one is about 3-months old the other one which is the broken one is only about 2-months old. I had them in anti-sync mode ReefCrest 100%. The powerhead started flashing from yellow to red (when in red the motor would stop) and then back to yellow every couple seconds. I assumed that the powerhead must be overheating so I unplugged it for the rest of the night. The next morning I "Clear the driver memory" mode and when the powerhead started back up in green it lasted about 1-second and now only flashes red and it is not doing anything. Please Help!!!

Hold down mode (pump blinks white)
Hold down mode/set (pump blinks yellow/white)
Cycle power to the pump by unplugging and replugging it in.

Somehow you programmed the pump's calibration sequence for auto-disconnect while the pump was attached to the tank and this is the result. The pump must be run in your hand for the auto-disconnect calibration sequence or else this will happen every time. The process above will clear out the calibration.
