You have marathon water heater?
Thermostat is probably bad. Has gone out of calibration.
Replace both upper and lower thermostats for $25 from local hardware store, takes about 20 minutes, turn off power, take photo of wires before starting. These thermostats can be adjusted all the way down to 90 degrees, and then dial up a bit to reach 110.
Copy following link for instructions how to replace thermostat yourself.

If problem continues, then replace both elements.
Elements are special order made specifically for marathon.
Requires 1-7/8" socket to remove elements.
Upper 3800 watt, order part SP610130
Lower 3800 watt, order part SP210197

Unless you are getting more than 150 PSI, you should just replace the valve. It has dirt in it.

Turn power off. Open covers and inspect for burned parts.

Test elements. Marathon takes specific element, and does not use generic element from hardware store.

The Rheem MR50245 is an electric water heater if has no pilot flame.

Turn off the electricity.
Turn off the water valve going into tank.
Open a bathtub spout to let hot water pressure off the tank.
Check top of tank for any leaks.
Open the top access panel and see if element is leaking.
Open bottom access panel and see if lower element is leaking.
The reduced pressure on the tank will slow the leak.

If element is the problem, you can squeak by for a while by turning on the hot water heater only when you need hot water.

These elements may be available locally, but they are not the same as 'ordinary' tank-type electric heater elements that you buy at the hardware store.
Buy more than 1 element because the Marathon elements have problems.
One of the reported problems with marathon elements is the high price of stainless steel replacement elements.
Drain tank.
Replace element.

It could be that the reset button is faulty and will not reset. they are not very robust and can fail when operated repeatedly. The thermostat could also be open circuit especially if the original element had failed. Try replacing both reset and thermostat controls.
