My KSTAD50B dehumidifer does the same. It will run for about 90 minutes and then decide that the basement is too cold and then throw the EC error. Yes, I can unplug it, plug it back in, and hit the power switch to turn it on again, but I purchased this dehumidifier to run in my basement without so much manual intervention. I have taken it out of Continuous mode, and I'll see how it performs now. I'm not hopeful.
