citylab Posted October 13, 2011 Report Share Posted October 13, 2011 Hi! Had this problem for a couple of days now and tried just about anything with the troubleshooting guide. I've tried switching out the heater but still get the same error message. If I just switch the cords with the NS heater I get: NS HEATER abnormal instead, so the problem is definitely not the heater itself. Also tried calibrating the temperatures for each tank, but after that I got E905: ABNORMAL TEMP. RESET DATA, which also doesn't help carrying out. Can anyone help me with this? Thanks:) Quote Link to comment Share on other sites More sharing options...
