Why is my Kelvinator Water System water not hot enough?
- SScott MillerSep 4, 2025
Several factors could be responsible for the water not being hot enough in your Kelvinator Water System. Check if the cold and hot water lines are cross-connected. If a tempering valve is installed, ensure it isn't set too low or malfunctioning. Also, make sure the gas supply valve is fully open, the gas line is properly sized, and the gas supply pressure is adequate. Verify that the set temperature isn't too low and that the combustible air inlet or exhaust outlet isn't blocked.
