Tunze ato 5017

[reefermadness31]

I'm having some problems with my ato. It was working fine until about a week ago. Now after the initial 20 seconds or so of it running on startup it will fill for about 5 seconds. Turn off with the green light flashing too high for a bit then keep repeating this process until the float trips. Any help on what is going on?
