This is something that has had me stumped ever since I’ve owned my 1963 RCA Whirlpool Imperial Mark XII washer, it always filled perfectly fine on hot and medium/warm water temperatures but is slower than molasses to fill on the cold temperature despite me having good water pressure. Water trickles into the tub on cold but if I put it on warm and turn the hot water off at the faucet on the wall, the incoming cold water flows like it’s supposed to but when on cold it just trickles into the tub. Anyone else have a Whirlpool washer with the Three Solenoid Non Thermostatic that does this or not?
