Hello, Jeffers! Your safety is our number one concern! And for your dryer, the built-in Flow Sense warning in your LG dryer is made to help avoid poor performance caused by restrictions in the dryer vent exhaust system, thereby alerting you to any issue with your dryer vent so you can get it fixed. To clear the flow sense error, you would need to either have dryer vent cleaning done, reroute the dryer vent, change the hose behind the dryer, or shorten the length of the dryer vent. Your concern with the LG top-load washer not draining could be a couple of things, such as the coin trap or pump filter being dirty. To check and clean the coin trap: Unplug your washer and remove the drain hose from the back of the machine. Locate the coin trap on the front of the washer and remove it. Clean out any debris that may be blocking water drainage. Should you need further assistance, please contact our LG Social Support team through Facebook or Twitter using the hashtag @LGUSSupport, including the dishwasher's model and serial numbers. We will be delighted to help you! ~Rita
