Hi! My name is ***** ***** I can assist you with this. I may need some additional information from you first in order to give a complete answer.

This can be caused from several things and dirty tank sensors are one of the leading causes. I would get some Happy Camper Extreme Cleaner and put in there and see if that corrects this. If not, it may be a bad connection or bad control in the toilet. I am attaching a link to that site in case your local dealer doesn't stock it. Amazon has it as well. Great products and the most economical to use. Hope this proves helpful here. Please get back to me if you need more later as all follow ups are included in our fee.
