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.

SOURCE: I have a rheem 81VP2S Electric water heater it

Hi , when a breaker trips immediately, that can indicate a problem in the circuit. But the circuit stays on for a bit , then trips, so there is a problem with the heater. Could be that a thermoastat or heating element is shorted out. You can replace these items yourself, I would check the heat element first. Or there may be some corosion residue around the heater terminals.

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

Boiler is not turning on


Check the breaker box for a tripped breaker, it should be a dual breaker and if only one side trips, it will not heat. If breaker vibrates, chatters or smokes, it must be replaced.

Electric shower just installed cuts out at fusebox after being on for about a minute

Circuit breaker is tripping on electric shower?

This could be absolute danger until more information is known.

1) Breakers trip because they sense heat, because the wire size is too small, or breaker size is mismatched with wire. Or breaker is loose on busbar.
Copy following links to determine correct wiring and breaker:
http://waterheatertimer.org/Color-codewire.html
http://waterheatertimer.org/How-to-wire-Tankless-electric-water-heater.html

GFCI circuit breaker will trip because of same heat condition described above, and also trip if ground fault is detected.
Water leaking into element will trip GFCI.
Absolutely you need to get this problem fixed before shower is put back into service.
Call electrician, or the installer, or the manufacturer, or all.

I have a Rheem Marathon 105 gal. electric hot water heater. No hot water ....


Check 240 circuit breaker.
Open top cover on water heater and push in ECO red reset button.
If reset button will not reset, then replace thermostat.
If reset is not tripped out, then either upper thermostat is bad, upper element is bad, or water heater might be getting 120V instead of 240V.
If you have some hot water, then best suspect is lower element.
