My 87 year old mom just bought a house and plumbing all seams fine except water never really gets ot in the kitchen sink. The dishwasher (new per seller of house) doesn't go through the cycle correctly and just keeps washing. Mom can't fford a plumber so you are it.

From your post I will assume other faucets do get hot so the problem is just at the kitchen sink, right? Most likely a clogged hot inlet on the kitchen faucet. Shut off both supplies to the faucet and remove the cartridge or stem. Clear debris, hold a towel tightly over the hole and turn the supply on and then off to flush the lines. Let me know if you have any trouble with my directions

I will try this tonight when i go over to my moms house. Thanks for the advice. I will let you know what happens. Take care and god bless.
