Answer to: frigidaire works ok, bout only fills with cold waterJust fixed a similar stacking washer with the same problem. Set your wash temperature to hot and start a fill. If very little water coming in try this... Turns out there is a filter screen inside the hose connections on the washer. The hot was plugged up due to some previous water line flushing. A good scrub with a Q-tip and hot water was flowing happily again.
