The answer to 'garbage disposal no hot water' is that the issue is likely caused by a problem with the hot water supply, not the garbage disposal itself. This could be due to a malfunctioning water heater, a blockage in the hot water line, or a problem with the plumbing fixtures.
Some common symptoms include only cold water coming out of the faucet when the garbage disposal is turned on, or the disposal running slowly and not draining properly. To troubleshoot, check the water heater temperature and settings, inspect the hot water line for any blockages or leaks, and ensure the faucet and disposal connections are secure.
