Check the circuit breaker or fuse for the electric water heater. If the gasket sticks,remove the new gasket from the replacement element and re-use the old gasket. Heat the element with a propane torch and see if that loosens it. Lime life elements are ultra low watt density and have a high quality nickel and stainless steel surface that discourages the build-up of lime scale. Provided you have the same wattage and voltage, you can use a low watt density element to replace a high watt density element. Next, check the reset button on the temperature cutoff it's usually a red button that's located above the thermostat inside the upper access panel.
For example, you may choose to increase or decrease the unit's holding capacity to accommodate a changing family.

Below we show how to find the thermostat control and reset switch for an electric water heater. If the reset button pops out again, check the elements. Even though these are a lower watt density, there isn't a loss in efficiency. Stop the water from the main water stop cock, open a hot tap, and leave it open to drain any water left on the pipework and in the expansion vessel. Low-watt density heating element is what you should look for, as it provides an even distribution of heat, which makes it last longer.
We'll drain the tank later. Either way, the minerals could cause the elements to burn out. Wiring details provided with these water heater controls are at At links below we continue with more diagnostic testing and repair procedures for electric water heaters, looking at the high limit cutoff switch, the high temperature reset switch, and testing and replacing bad electric water heater electrodes. To find the reset button on a water heater element if there is one you'd need to - turn off electrical power to the heater - remove external insulation - open the one or both access covers that are illustrated in our photographs above. Threaded base made of nickel plated steel. Scale coating a water heater element can also reduce the quantity of hot water or cause heating element failure - a topic we review in more detail at at. If that doesn't work, shut off the water and replace the fittings.

Gas water heaters heat the water in an entirely different way. Open the drain valve counterclockwise and let the water drain from the tank to just below the level of the heater element. First, check the circuit breaker. High voltage If more than the design voltage is supplied to the heating element, the element will burn out.
Loosen the element a few turns and you should be able to see if the gasket is stuck to the tank, just use a small flat bladed screwdriver to pry loose. If hot water is running for a short time before it gets cold, the problem is with the bottom heating element. Each panel houses 1 water heater element. You can understand why these simple diagnostic observations usually work on residential electric water heaters by looking at Carson Dunlop Associates' sketch at left. Dryfiring can be recognized as the element shaft is annealed so soft that you can bend it with your fingers and the plastic element is melted. If you need to replace the heating element in your electric water heater, you may be thinking that you need to first drain the tank.
This series of articles describes how to inspect, operate, diagnose, and repair electric hot water heaters. If it isn't, you can find this information on the water heater's nameplate or thru a simple online search with the heater's manufacturer and model number which is listed on the name plate. Fold the insulation outward and away from the heater element. Install the new element, refill the water heater and plug it back in or switch on the appropriate breaker. Check the water heater thermostat condition and its internal thermostat control reset switch. If you're replacing a water heater, you can replace it with the same type of unit.
