apostolakisl Posted February 17, 2019 Share Posted February 17, 2019 Just before we were about to have 25 people for a dinner party, the house announces "water trouble, master bedroom" and shuts off the house water. So I had to go check. . . which included needing to pull off a panel to get under the tub, just what I wanted to do as getting things ready for the party. I checked all 4 water sensors in the master bedroom including one behind the washer/dryer in the master closet. All was dry. Voltage was reading 3.8v. Not a full short that you expect with actually wet sensor. So I bypassed the zone and left it to today. Today I looked again and could find nothing wet. There was a lot of lint behind the dryer that had gotten under the sensor. I cleaned the lint away and now all is fine. So, in summary, it seems that excessive lint can make a water sensor partially short. I'm using the GRI normally open water sensor. Anyway, you might consider doing some routine checking on water sensors behind a dryer for lint to avoid false alarms. Link to comment Share on other sites More sharing options...
kclenden Posted February 17, 2019 Share Posted February 17, 2019 I guess if a water sensor is going to trip, I'd rather find lint than water. ? Link to comment Share on other sites More sharing options...
