Disco 2 Nanocomm does not bleed after 0.5L or more of brake fluid was lost in braking system

Hi! I need a urgent help for brake bleeding. My front left brake hose banjos bolt was snapped when undoing the day before. I got a new one today. Unfortunately I could have lost some brake fluid although I kept hose banjos end high enough afterwards. It takes about 0.5L to refill the reservoir to max. When I was bleeding with nanocomm, I was not seeing fluid out of caliper. The caliper has been empty, ABS module could have lost some fluid. I tried power bleeding and front left test. Both works but no flowing fluid, what should I do in this case? manual bleeding or tried ABS module bleeding?

Hi. You have to pedal bleed it well first as the master cylinder to pump fluid through the modulator, that's compulsory, just after that start to power bleed,... and in the correct order as in the book not randomly

Thanks! sierrafery. I wonder if air was also trapped in ABS module circuit B for empty reservior. Hope to flush it with new fluid after pedal bleeding.
