Okay the kitchen faucet doesn't allow warm water to follow through. The cold water comes but when I turn the knob to warm nothing comes out. What's wrong? When I used the dishes water the warm comes and it works perfectly, its just the kitchen sink that where the warm water isn't coming out. Is there a major problem? Do I have to get the entire sink replaced? Is there any way I can solve the problem on my own?

Need more info. Make and model of faucet.

Single lever? Spray hose?

Any plumbing work done recently?

Try to answer Chucks questions but this is not going to be a big problem. Sounds like the hot water inlet on your mixing valve is clogged. A picture, brand/model would help us tell you how to clear it. It is likely a cartridge problem
