I cant get the water temp below 125 and I need to for our day care. I have the lower thermostat set to 110 and it still is 125 to 130 degrees. Is there something else I need to do. There is a upper...


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

Can I install 4500 wt elements in a marathon MR50238? The tank specs are the same as MR 50245.


1) Product warranty will be voided if you install 4500 watt elements in year-2008 model MR50238 3800 watt marathon tank.
Older 3800 watt element models have been discontinued.

2) Copy following links for Marathon resources:
http://waterheatertimer.org/Review-Rheem-Marathon-water-heater.html
http://waterheatertimer.org/How-to-replace-water-heater-element.html

3) Product warranty is voided if element wattage exceeds label on side of unit.

4) Marathon has a problem with elements burning out frequently.
To solve this problem, they suggest installing element with lower wattage, such as the 3800 watt.
Upper 3800 SP610130
Lower 3800 SP210197

Rheem marathon tripping breaker


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.

How do I wire around upper heating element until I can get an other one to replace it?


Question posted under marathon electric water heater.
Marathon is 240Volt dual element non-simultaneous water heater.
Non-simultaneous means that upper part of tank has to reach temperature before power is sent to lower thermostat and element. So if upper element is bad, then water heater has no hot water.
http://waterheatertimer.org/Replace-anode-rod.html#audibleBW

1) You need to by-pass upper element without by-passing upper thermostat.
2) You should never by-pass upper thermostat because it has ECO-reset protection.
http://waterheatertimer.org/How-water-heater-thermostats-work.html

3) Open following link for image of wiring:
http://waterheatertimer.org/images/Marathon-wiring-700.jpg
4) Take photo of your wiring in case color code is different on your specific model

5) Look at upper thermostat.
Remove yellow wire from terminal 2 on upper thermostat, and cap off temporarily.
Remove red wire from terminal 4 on upper thermostat, and move it to terminal 2 on upper thermostat.
6) For more effective operation, look at lower thermostat.
Remove black wire from lower thermostat terminal 1 and move wire to terminal 2 on lower thermostat.

I just installed a marathon 50 gallon 4500 watt, hot water heater. I do not have hot water. The wiring to the upper element and thermostat all test at 240 volts. The lower element and thermostat show no...


The top element should be heating if there is 240 volts across the element terminals. I take it that the top element is the booster element. The thermostat for the top element is normally a 2 pole thermostat which switches the neutral to the bottom thermostat once it reaches temperature. Once this occurs then the bottom element will start to heat. The top element will only come on when you use all the hot water. Is this supply on the off-peak rate? When testing always check the voltage across the element terminals.

It sounds like upper or lower thermostat.
Thermostats turn off one leg (or one wire) in the 240Volt circuit, so each elements will test for 120V even when thermostat is off.
When thermostat turns ON, it closes circuit by adding the second leg to 240V circuit, and element turns ON.

Take 30 minutes and troubleshoot before replacing parts:
