I have a fairly new front loader washing machine. I have noticed the past month or so when I start laundry the laundry room and adjoining rooms get a strong odor similar to rotten eggs. The next load of wash I do, will have no problem. It ony does this on the first load of wash after not using the washer for a couple of days. I don't know if I should call a plumber or a washing machine repairman. Any suggestions on what could be wrong?
