My kitchen faucet jumps, sputters and stops and squeals when water temperature reaches straight hot
Sounds like the anti-scald feature is working as designed. i.e. it's not SUPPOSED to let you burn yourself with excessively hot water, and the operation is as designed.

Dishwashers are not intended to operate with hands in them, so they normally have no anti-scald feature, and indeed may have a supplementary heater to raise the temperature even more for sanitizing.

Perhaps your hot water temperature has changed slightly, if this "just started happening" after 17 months.
