Just tried them both. Neither the rinse cycle nor selecting only hot or only cold change the noise. Good suggestions...hadn't thought of trying those!

I've been living with this problem for awhile now. When the washing machine fills with water, it produces a screeching sounds that is so irritating. I've checked the screens on both the intakes of the fill valves and on the hoses, all clear. I've turned down the flow of water while it's making the sound, no change. Switched from rubber to SS hoses, no difference. I'm assuming it's the fill valve itself. Could air be somehow trapped in it and if so, how do you bleed the system. Any thoughts on what could make this noise? Thanks.
