Mp40 qd red light flashing only when in battery backup mode

Edit: controller is flashing red/green/white

i just replaced the battery in my battery backup. Tested at 13.2 v, plugged everytbing in and went to test it by unplugging the mp40 power supply. To my dismay the pump stopped and the controller now flashes red.

I've found some links on this but they're dead.

What's the fix?

i just had my power supply die on a very old mp40. and when it did, i got a flashing red light. Maybe whatever you did cooked the power supply? Or just coincidence.... I wouldnt really know, not too savvy in that area. but.... i got a hold of ecotech support and they were responsive and they sent me a new power supply without me even asking.

Pump works fine in non battery backup mode.
