Welcome! Your question will be answered in detail. UP to 48 hours step by step coaching on diagnosis & repairs $38 additional.
The float in the tray could be stuck, physically inspect that, it is more likely however the filter door was not re-installed correctly after you changed the filter.
You will notice the switch, when you have the door off... refit the door and let me know how all that goes.
This is trouble shooting step #1.. we keep going as needed until we get the problem solved.
