Hi. In parallel to my new LG Waveforce washer with one question, I also bought an LG DLGX5171 gas dryer. This thing works great, with one oddity. When first using the dryer after it's been sitting for a day or so (even empty), the first 30 secs or so there's a loud, rhythmic thumping that sounds like the rollers have flat-spotted. After running for a very short time (even before the heat starts) the rollers eventually smooth out, then it's quiet for the rest of the load, and even quiet if you run another load shortly thereafter. I've not experienced this so much with other dryers in the past, and wondered if it's just the nature of the beast, so to speak?
thanks - andy
