In the process of a failed attempt at fixing our dishwasher, I turned off the hot water valve beneath the sink. After turning it back on, the hot water side of the faucet no longer works!
Our faucet looks like this, with a single lever to switch between hot/cold. The faucet is attached to a long hose so it can be pulled out. The "cold side" works just fine, but turning the handle to the "hot side" results in the flow of water stopping.
Beneath the sink there are two twist valves- one for hot water and one for cold water. I am able to turn the cold valve on/off and it stops/resumes flowing water as expected, unfortunately this is not the case with the hot water valve. With the hot water valve open and the faucet turned on (on the hot-side) I can feel the hose that connects the valve to the faucet head warming up. This leads me to believe that perhaps the valve inside the faucet has failed?
Is there anything I can do to further troubleshoot the issue, or should I call a plumber?
