Agree on the Tecmas. Never had a moment's trouble with them in 5 seasons

I have initmate knowledge of more than one of jfm's toilets after one of the aforementioned teenaged log-blocker incidents...

Back to the original question, the only thing i can think of is that the thin-filmy switch panel is somehow corroding/shorting? There is no sensor afaik to trigger a "before' flush? I'd blame my SSB if it was in the same country...
