Hey, so I don't really use forums like this very often, but I'm in need of some answers please. I moved into a newly built 2 story townhouse. In my kitchen (ground level) there is a large closet with a brand new washing machine and dryer and right next to that closet is another large closet which contains the hot water heater. Everything was brand new and freshly built when I moved in about 9 months ago. A couple months ago I started noticing a musty or mildew like smell coming from my washing machine, at least I thought that was the problem. I used the self clean mode with some bleach and started leaving the washing machine door open so it can vent and dry better between uses. It seemed to work and all was fine, until the next load of laundry I did. The smell was back, and then by the next day it was gone again so I didn't think much of it. Since then I have noticed that while doing laundry the smell gets really strong, but it isn't coming from the washing machine, instead it is coming from the closet containing the hot water heater. I've looked for moisture or a leak or something, but there is nothing. I let the room air out over night and it is gone, but like I said as soon as I wash another load of clothes it is back and strong and coming from the WH closet... any ideas or suggestions??? Please help. I googled and googled, but I haven't found anything with that specific problem. Thank you!
