I bought a Fluval Vuetec E300w heater for my tank last Sunday. Set it to 23c and it warmed the water up nicely and kept it at the set temp with a green LED showing. This was fine until 2 days ago when the display showed a blue light and regisstered the temp at 22c. I initially left it as I thought the temp had dropped and it was in process of heating up (no indicator to show it is on = annoying). That was in the morning, when I returned home in the evening, still blue showing 22c!
Last night, turned it off, left it in tank for about 3 hours. Turned it on and raised the set temp up to 24c. When it was initially turned on, it did its diagnostics and then the blue light was flashing registering 20c. I left it, went to bed, this morning it was still blue and showing 22c!!
Is his thing busted? Insights very welcome before I pack it up to get an exchange ...
