After a power outage the tank is not heating up. The fuse is ok
We have situations like that where even with an electrical meter it may appear that both sides of the panel have voltage when actually one of the main breakers or fuse has blown. If that is the case power flows through some 220 volt devices to feed the second side of the panel but no 220 volt appliances work. If that is the case then the voltage will not be 120 volts on the second side but some lighting has a brown out or too low of a voltage. If none of this is happening then you have blown your element. To prove that... verify with a multimeter that you have 220 volts on the element.
SOURCE: Water heater with electonic igniter will not work in power outage
What type of heater is this? I need to know the model name and make and then we can go threw the process of how to do it. Most gas heaters do not have power to them and I only know of a few tankless heaters that do.
SOURCE: ON-DEMAND WATER HEATER NOT WORKING
I am assuming that this is an electric unit? The heating elements could be bad. I would contact the manufacturer for a service manual for your unit. There you will find instructions on how you might be able to reset the unit if possible. One thing you can try is to shut all power down to the unit and then restart. Also check for any "reset" switches on it as well.
SOURCE: Power outage caused c8 / 76 error - No Hot Water
How old is your unit...if less than 5 years old tell Polam/Rheem customer support you are recieving a code 76 error - this is a loss of communication between the remote and the burner control assembly. Part will be covered under MF defect warranty. However, the part is covered....the labor to install is not.
If you are slightly technical you can install the part yourself...customer support will walk you through the process and they give you a step-by-step procedure to follow.
SOURCE: Too much water draining from Vulcan Electric H/W relief valve.
Dear Julie. Do you have an expansion tank installed? If so it is probably waterlogged. If you come home shower etc. use lots hot water then go to bed or leave the cold water in your tank heats and expands as it heats. In the old days a toilet ballcock valve would relieve this pressure but modern toilets with diaphragm valves wont so the pt valve relieves pressure. Installing an expansion tank on the cold water line near the heater will absorb the extra water & stop the pt valve from activating.
SOURCE: i switched off the power to my electric rheem 142
Turn power off to water heater at breaker panel, remove cover where electrical cord is, and check behind it for thermostat, with red button in center, push it in to reset. It may have tripped for some reason when power turned back on to it. Do you have a multimeter, to test for power at heating element?
