Continental Girbau Inteli Washer Error Code 503: Lock Door 1 On
Code 503 (Lock door 1 on) is a door message. Press STOP on the keypad, open and close the door, and restart the program. If 503 keeps returning, a technician checks that the door hinge switch works.
Low: the sheet treats it as a door message that normally clears with an open and close.

What does Continental Girbau error code 503 mean?
The sheet lists 503 as Lock door 1 on, with the instruction to open and close the door. The control asks the lock to engage when a cycle starts and expects the door switches to confirm it. If the door state and the lock state do not agree at that moment, it stops and shows 503, and the sheet's remedy is to reset by pressing STOP on the keypad, open and close the door, and restart the program. If it repeats, the door hinge switch is verified. The table gives no cause list, so the checks do the narrowing. The rows for 503, 504 and 900 share the door-lock and locked-program lines in the printed table, and the text alignment is slightly ambiguous, so we keep to what the sheet clearly says about 503.
