Company Policy; Human Factors; Procedure
Did preflight inspection of cockpit. Pushed back and started # 1. After start got ECAM (Electronic Centralized Aircraft Monitor) with horn about hydraulic and flight controls. Hydraulics were in the normal range but were not feeding the systems. Started getting fumes in the cockpit so shut down engine. Called Maintenance and returned to gate. Maintenance comes on and finds 2 guarded switches on maintenance panel in off position.Maintenance not returning aircraft to airworthiness condition after tests. They were extremely hard to spot from our vantage point.Return switches to normal after system checks. This is setting us up for failure.
After pushback; and after number 1 engine start; we received a hydraulic system warning message. We shut down number one engine and the warning went away; and we returned to the gate. It was discovered that one of the guarded maintenance panel switches was in the not normal configuration.Maintenance performed the checks and did not return the aircraft system to normal configuration. The guarded button was not discovered in preflight as being on.Would change maintenance checklist to read; maintenance panel: keep guard switch cover in 'open' position to highlight button is in the 'not' normal configuration. With the switch cover closed; it is difficult to ascertain button position in all ambient conditions.
A321 flight crew reported receiving an hydraulic anomaly ECAM during taxi out which resulted in a return to the gate.
