Electric water heater not working


My hot water doesnt stay hot for more than 4-5 mins at a time and it takes really long time to recover, what could be the problem. Take into consideration that this is a new unit. Thanks

There are usually two heating elements, top and bottom. One may not be working or is set for the wrong temp. They usually have a popout breaker in the thermostat, that may be tripped. CAUTION, 240VAC on those wires.

Another possibility, the dip tube that feeds cold water to the bottom of the tank may have broken. The dilutes the hot water at the top with cold, making it seem that the heaters are not working.

Assuming this is a standard household water heater supplied by a 240 volt circuit, step one is to verify that it is receiving 240 volts from the panel using a voltmeter.

Electric water heater not working


Sounds like a unit I had to troubleshoot recently. A young lady had her Dad install a new unit in her house. The new unit took a long time to heat the water and when she took a shower or washed dishes, the hot water ran out quickly. The unit was getting full 220V power, the dip tube was fine, all was well until I got to checking the thermostats. It took me a while to find this one. This unit allowed only one thermostat at a time to come on. The bottom unit had to have the temp satisfied before allowing the top thermostat to come on. Really weird to me. After questioning the lady, they bought the "one she could afford"--the cheapest one. I changed out the thermostats for "quick recovery" units and all was well. I would check to see if yours is a "quick recovery" type or one like this unit was. You may be able to exchange it under warranty. David

I purchased this unit at Sears, a kenmore 55 gallon water heater. I purchased this unit about a month ago with problems from the start.

The top element is supposed to come on (and in most cases the bottom element goes off) when cold water gets near the top of the tank. When the top of the tank is heated the power is switched back to the bottom element. The heater being referred to could have been incorrectly wired internally at the factory.

Water heaters that allow both elements to be on at the same time require a higher ampere branch circuit and some homes might not be able to handle them without an electrical service upgrade.

I believe you are correct Allan.

I was told by someone that maybe the person that installed it may have done a 'dry run" so the top element maybe shot. Its a 5500w element so its possible I have to purchase another one

Whoever installed it should be called back and given only the information that it heats real slow.
