Leak sensor not detecting leaks

I’ve deleted and re-added it several times but it ignores the water it’s sitting in. When I re-add it to the system, it detects a test leak, but then won’t clear the allert. What the heck? These used to be reliable.

Is this a new or an existing leak detector? Have you changed the battery?

you can try if a magnet close to probe connector on sensor body will trigger. it looks like probe magnet trigger the event
