Flashing red lock light on toilet

[Sharron]

Cutwater 30 CB 2015

Lock indicator flashes red when toilet is flushed. Toilet tank level indicator is green. Tank was emptied 4 days ago. Two people also using marina facilities. What can cause this? Is it battery related?

Just took the bed apart.
Tank level is below the yellow sensor.

Thanks

Here’s a link to the installation and operation manual. Your answer is in there somewhere. Good luck with this sh**y situation.

With my 1 year-old Tecma toilet, the Red Lockout light remains on if lockout was disabled, even if the holding tank is emptied. To turn it off and return to Enabled Lockout mode I would need to press both buttons twice.

Good luck!

On inspection the holding tank was only ½ full. The red lock light flashed because the battery was down to 9 on the charge instead of the usually 13+. Inverter battery switch had been changed when we had a one night dock at the hall-out yard to accommodate lower amps on the pedestal. We were not aware that it had been changed. Thankful for the solar power that kept things going. In tracing the problem, we now know why the refrigerator wasn't cooling like expected and why the sound went out on the salon television even though we had a good picture. Once the house batteries were back to full, everything was running normally again.
