For the last 30h the screen on the Sakura - Tissue-Tek TEC 5 has been showing:
"Power outage Press Exit to verify system status" and keeps flashes to a blank screen after about 4-5 seconds.
When pressing Exit before the screen turns blank, it says "warming up Please wait", but also that screen soon switches to a blank screen and then displays the previous power outage message again.
Over the last day, the initially solidified Paraffin has indeed melted, but there has been no change in the display.
When entering the service mode by pressing the Exit key, the screen stops turning blank every few seconds. Running a test on the cooling unit works fine (though the unit cools down very slowly over 15 mins). During that time the screen does not flash and continuously displays temperature readings for all sensors.
However when testing heating, or heating+cooling, the screen goes blank within few seconds and goes right back to the power failure message. In the brief second that the temps are visible, all are about 60C except for line 1 which is only at 45C.
Is it possible that the heating element for L1 is broken and short circuits every time it's turned on, leading to the system to restart every few seconds?
Any advice?
