After I came back from my trip, I found the toilet has no any response, sensor LED no any color. I tried to solve the problem with the methods you told other people but failed.
Thank you for your question on the Delta Brevard Toilet with Flush IQ. I am sorry to hear that you have been experiencing issues with your toilet not flushing and I will be more than happy to assist you.
Please try the below reset procedure and feel free to give us a call to let us know how the unit responds:
1.Turn your water supply off.
2.Perform a Manual Flush.
3.Take out batteries.
4.Unplug the white overflow sensor wire running out of the back of the tank.
5.Place your hand below the battery pack, you should feel the water sensor which feels very similar to a screw, manually fill tank with bucket/pitcher to the tip of waterline sensor.
6.Plug the white overflow sensor wire back in.
7.Replace batteries with the two positive batteries facing up on the Left and the two negative batteries facing up on the Right.
8.Replace the lid and watch the sensor, it should display a Blue, Green then Red light sequence, then the sensor will appear blank.
9.Turn your water supply back on and wave your hand two inches away from the sensor.
10.The sensor light should appear solid Blue and flush normally.
Please feel free to reply to the email I have sent you or give me a call back at 855-345-1345 Opt 5 if the issues you have been experiencing persist even after resetting the unit to let me know how the unit responds and which lights in particular appear on the sensor.
Eagerly awaiting your response,
