Only the water level sensor will have this effect on disabling the system. Unplug the water level sensor and let me know if the system reboots.

Under normal sloshingm the water level sensor will not interrupt the system from injecting. If condition persists for a timed period or the level probe is parled on the empty position for more than 20~ seconds, the system will turn off.

If unplugging the level sensor does not cure the problem. Check if the wiring "yellow/black" is shorted to the chassis.
