Removed and reinstalled aft left emergency exit hatch per AMM (Aircraft Maintenance Manual). No fault of being open on ground on ECAM (Electronic Centralized Aircraft Monitor). While climbing at 9;000 feet amber fault notification appeared on ECAM. Flight crew had a precautionary landing and it was troubleshot by day shift and released for service. Flown to ZZZ with no faults. The fault came back a second time and final repair appears to have been the inner seal of exit hatch. Lack of attention to detail of inner seal. Printed AMM did not have the photo figures to go with it. Inspected inner seal from interior with inspection mirror and noted ECAM had no amber faults. In my eyes and coworker being my monitor and challenge; this hatch was fully secure.More attention to minor details and printing photo figures with each and every aircraft manual. Learn from this experience moving forward and make sure something like this doesn't happen again in the future.
Technician reported an ECAM warning for a emergency exit door warning that repeated on a subsequent flight; resulting in a precautionary landing and additional repairs to the door seal to correct the malfunction.
