I also realise, procedures will be different between various types/makes of rebreathers
I can only speak for eCCRs but I've always thought that faults fall in three types:
1) Loop gas is wrong.
2) Don't know what the loop gas is.
3) Loop has gone away.
1) You have cell readings you trust but the injection system is dud. This is time for the manual modes you learn in CCR 101. I might just continue the dive unless I think it is the batteries.
2) The dead handsets problem or the cells are all reading differently. With a flush you may be able to decide which cell(s) to trust but otherwise you are into semi-closed or 'top-up' mode drills. This is the hardest one. If you're unsure goto (3). Definitely the end of the dive.
3) Flooded or CO2 break through. The easy decision. Bail out and get out. No-stop diving I'm onto the DIL and then the O2 once I reach 6m. Deco diving I carry my two 7s of bottom mix and 50%.
