This guide assumes that the electric water heater used to be put in properly and running as required ahead of the development of any problem.

Information provided by leading hot water plumbing company Inline Plumbing Many electric hot water tanks (including a Rheem Hot Water System installer) come with two thermostats; the primary one near the top of the tank, and the second one close to the bottom of the tank. Both thermostats are covered by detachable steel cover plates. Additionally, they are firmly pressed against the metal wall of the tank.

The first thermostat frequently has a high limit switch that trips as soon as the water is too hot. This shuts off the electricityl supply to the hot water system as well as the decrease heating parts. If you want to reset the prime restrict switch, simply press the crimson button.

With this heritage, underneath are a few issues you may also stumble upon and imaginable troubleshooting suggestions.

Drawback: The Water is Not Hot

Dispose of the duvet plate of the upper thermostat and check If the high restrict transfer has tripped. If the switch has tripped, reset it.
Subsequent take a look at If there’s power at the enter terminals of the higher thermostat (frequently marked L1 and L2). In case there’s no power, take a look at the wiring to the electrical water heater or your circuit breakers.

If the problem persists, and the best thermostat is applying energy to the upper heating component, take a look at the voltage at the higher heating component. In case power is present at heating element yet the component cannot get scorching, the heating component has a problem and should get replaced. However, If there is no power on the upper heating part, the higher thermostat should get replaced.

Drawback: Inadequate water or the water temperature too low

While the higher portion of the tank is scorching, the best thermostat gets rid of the energy from the best heating element and transfers the similar to the lower thermostat and the ground heating element. While the lower thermostat has a problem, the tank is never heated and water supply is greatly reduced.

First test the energy at the terminals of the higher thermostat where power is sent to the lower thermostat and the lower heating element. In case there is not any energy, replace the higher thermostat. On the other hand, if energy is present on the upper thermostat, then check If the energy reaches the decrease heating part. If energy is absent at the lower heating part substitute the lower thermostat. In case power reaches the lower heating element but it does No longer turn hot, change the lower heating part. A broken dip tube would possibly as smartly be the source of the problem. Take a look at If the dip tube is damaged and substitute it.

Downside: The water is Too Hot

Probably the most thermostats might be defective. First check the power provide on the higher heating component. If there is power at this element, the higher thermostat is indisputably defective. Subsequent test that there may be energy on the bottom heating component. If there may be energy, the thermostat has a problem.
You will have to additionally check If the thermostats are firmly driven towards the tank.

Downside: TPR Reduction Valve Leaking

The TPR valve operates If both the drive or the temperature will get too top. Where the inlet is instantly fed from the mains with no pressure relieve valves, then Whilst the water becomes sizzling, it expands and the water flows back towards the primary. In case of a blockage as a result of a faulty valve or bypass, the higher water extent doesn’t have anywhere to flow to and the power dramatically increases.

When you position a variety tank in line on the water inlet, it’ll provide a place for the larger extent thereby fighting the operation of the relaxation valve.
It’s also imaginable that the drive of town water has increased beyond the surroundings of the comfort valve.

Downside: Banging or Popping Noise

Accumulation of scale on the heating components can lead to more than a few noises during the heating process. If you here a banging or popping sound, do away with the heating elements and blank or substitute them.

Drawback: Odor

Some bacteria can react with the magnesium anode rod. This results in manufacturing of a gasoline that smells like rotten eggs. Clean the tank with chlorine bleach or amendment the anode rod to aluminium.
Downside: Leaking Tank
Change the tank.
