I’ve been using my washer and dryer for months now but since the last week-ish both my dryer and washer will either not give any warm water from the washer or give any “hot air”/dry the clothes in the dryer. The dryer could be running and spin for hours but clothes would remain cold and damp even when on the highest temperature setting. The washer also won’t use warm water in the cycle, when put on warm or hot temperature the clothes will still be cold. This seemingly came out of no where as I have not tweaked with the washer and dryer at all. Is it wear and tear? An internal issue? Piping? I don’t know much about washer/dryer machines so any feedback would be greatly appreciated.
