I get these faults because the door doesn’t open at the landing. It was recommended to replace the door operator board. I replaced it and that helped for about a week. Now the problem has returned. Any help would be appreciated.

You may be hooking the interlock. If it is always at the same floor, check the hoistway door lock for a little come and go while locked.
