If it trips the breaker you MUST have an Earth fault and or a short circuit to Neutral/Earth. You must get a Registered Electrician to look at it.

My Rinnai tankless water heater keeps tripping the breaker then when turned back on, it begins to beep and displays a code 12. What is causing this? It is new and this is the first time any code came.


Go to Rinnai and get a manual with the error codes... for example a shorted element will trip breaker... wiring problems can cause breaker to trip... anything that causes heat on wire to exceed amp rating of breaker will cause it to trip...

Eemax280t2t no hot water


see if the circuit breaker switch has tripped either partially or fully and reset it. Check for bad or loose wiring on the heater and breakers. The next thing is more likely the heating element is no good and needs repaired or the heater needs 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.

One of the breakers assigned to our Hot wtr htr has been tripping recently leading to loss of hot water. This has happened twice in the last month. After resetting the breaker things have worked fine,...


Breaker could be bad.
Let's do a quick check and save you money.
Open top cover on water heater and push in red reset button that might be tripped.
If reset is tripped, water heater should turn ON.
If reset will not reset, then replace upper thermostat:
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html
If reset is not tripped out, then it is OK, so test two top wires on upper thermostat.
Use cheap multimeter from home center, and set dial to 240-250-277 VAC.
Test across top two screws on upper thermostat to see if you have 240Volts.
To do full troubleshoot on ordinary tank electric water heater takes 30 minutes and multimeter
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

If water heater is not receiving 240V, then the breaker is suspect, or a wire between breaker and water heater is loose.
See basic water heater circuit
http://waterheatertimer.org/240-v-water-heater-circuit.html

Now let's look at circuit breaker:
Mark suspect 240V breaker.
Identify all your breakers, and also mark another 240 Volt breaker that is same amperage as water heater 240V breaker.
Turn off main breaker.
Take front panel off breaker box.
The wires and lugs on main breaker are HOT, so stay away from that area.
http://waterheatertimer.org/See-inside-main-breaker-box.html
Suspect breaker has 2 wires coming from breaker.
See if one or both wires are loose, and then tighten.

If wires are tight, then move these wires to the other 240V breaker that is rated for same amps as water heater.
Now turn on main breaker.
Put ear against water heater tank to hear bubbly fizzing sound.
This will identify if circuit breaker is bad, or if water heater needs a full troubleshoot.
It is not a good idea to run two 240V appliances on same 240V circuit breaker, so you may have to decide one or the other appliance until you can replace breaker.

I just replaced my old rusted out water heater with a new Reliance 606 and now I am having problems with the circuit breaker being tripped, usually during the night. It doesn't happen everyday but is...


I would check with your owners manual to see what they reccomend for minimum breaker size. I don't remember on this particular model but it may be a single element instead of dual element. The single element usually use more power than dual. I would also check thermostat settings if this is a dual element. They should never be set at same temperature. Also if it continues to trip breaker I would check all wiring,then replace breaker. Sometimes they do wear out and trip when they really shoul not. Hope this helps. Thanks

The therostat breaker keeps triping no mater what the therostat setting is. I have to reset the breaker each time i want hot water. Is this GE solution to save energy?


It sounds like the thremostat may be shorting out they are not to exspensive to replace.

It it constantly triping there is a wire touching somewhere.

Circuit breaker trips on electric hot water heater circuit


Check the voltage at the water heater. Sounds like the element is burnt out and is tripping the breaker.

If it is more then 5 years old I would check.install a new heating element.

I would say you have a bad element in the bottom.If the water is cold and heat until the top thermostat reach it tempture,then switch the bottom element and then the breaker trip.So replace the bottom element.
