Indicator light sequence not found in FAQ

After charging and turning the unit on, lights start coming up like normal but when getting the flashing lights to ready to put in the pool, the center light turn off but still have yellow flashing light then they turn flashing blue. Put the unit in the pool and it works for a few minutes, then get a red light and it stops altogether.
I took if out, put it back on the charger overnight and tried again with the same results.
Is there a complete guide to all of the indicator light possibilities available?
