remove the two covers one high and one low and set the temp higher. This time of year with colder water comming in the house the water heater has to work harder to raise the temp of the incomming water. In the summer the incommong water is much warmer. 40 gal is a small water heater and you will only get about 15 gal of hot water with the ice cold water entering the water heater as you use the hot water. You can get a bigger water heater. even better is to go tankless and a have never ending hot water and save money at the same time.

50 gal. Reliance electric hot water w/bottom element problems

Willard when you say it throws the reset button,do you mean the breaker on your fuse box of your home?
If you mean that then yes it could be a bad element.The bottom element takes all the abuse on a electric hot water heater. They can short out,and need to be replaced.

Water heater- not always hot

common problems i have seen are:

1) wife or kids hitting the OFF switch thinking its the light switch in the closet where my heater is located.

2) heating element has died. you should have 2 elements in this heater. when one dies, the heater cannot keep up with the demand of heating 50 gals of water.

if there is a warranty, then now is the time to exercise it.

if no warranty, then it is possible to troubleshoot each element to see which one is dead if you are handy with a voltmeter and electrical wires. if comfy, i can provide steps to narrow it down. list the kenmore model number if you reply.
