I am guessing this is an ele water heater and the temp setting are not the problem.
Problem: Not enough hot water or water temperature too low.
When the top of the tank is hot the upper thermostat removes power from the upper heating element and transfers the power to the lower thermostat and heating element. If the lower thermostat is defective, then the lower portion of the tank will not be heated and the supply will be greatly reduced.
Check for power at the upper thermostat terminals where the power is sent to the lower thermostat and heating element. If there is no power then the upper thermostat should be replaced. If there is power then check for power at the lower heating element. If there is no power at the lower heating element then replace the lower thermostat.
If there is power to the lower heating element then it should be getting hot. If it is not, replace it. Another possibility is a broken dip tube. Check for a broken dip tube and replace if necessary.
The dip tub is located under the fitting where the hot water comes out.

When using my oven to bake, usually at 350 degrees, it cycles off but doesn't cycle back on. The first few times i used the oven, I could hear it cycling on and off but now it does not cycle back on. The temperature display continues to show 350 degrees but the oven is not nearly as hot after initially reaching 350 degrees. I have waited at least 10 minutes to see if it was going to ever come back on and it does not. I have cancelled the baking cycle and then immediately restarted it and the preheating temperature has gone down to 165 degrees causing my baked goods to be gooey and raw. Was it designed to work this way or has my oven malfunctioned
