I am trying to install a new water inlet valve (part number 2188746) but I cannot get the old water lines off of the old valve, any tricks?
They’re probably attached with quick-connect fittings: Push in on the ring next to the body of the valve, while pulling the water line away from it. There may be some pressure built up, so you’ll likely see some water come out as you disconnect. Make sure the source water is off before you do this.
