The tap is turning but no water comes out', taps are 10 yrs old, all other taps work fine

If all your other hot water taps are working fine, check for a hot water shut off valve under the sink, and make sure its on.

First remove the aerator and tur the water on. Still no water?
Shut the water off under the cabinet ands open up the faucet. Remove the cartridge and check and clean the inlet ports. While the valve's open place a pan over it and turn the water on to flush out the supply. You should have a full sream when you do this. If not let me know. Good luck, Tom
