What to do when the electric water heater does not work?

Breakdowns are a nuisance and if they prevent you from showering with hot water, certainly much more. And it is not always when the electric boiler does not work that you have to call a technician. There are many things that you can fix yourself.

Calling a technician is, as a general rule, the best thing to do in the event of any breakdown but, depending on your skill and knowledge, it is something that you can save in some cases. We detail the most common ones.

How to detect a fault in the thermos?

The function of the electric water heater is to heat the water so that will be the first clue to know if the water heater is broken: there is no hot water. However, there can be several reasons why the electric water heater does not work.

Check first if you have several electrical appliances on, it may be that you are using more power than you have contracted and that is why the differential jumps. It may also be triggered by external factors. First of all, it will be to verify it.

If the differential drops when you raise it, it may be that a wire has a short circuit. Remove the lid of the thermos, after checking that the power is off, and check the cables.

Then check the thermostat and resistance to see if they are working properly. If the electrical system is okay, check for any water leaks. Here it is also important that the current is switched off.

If you find a leak, the first thing you have to do is empty the thermos before you start to repair anything. If you don't find any of these problems and the electric water heater still doesn't work, call a technician.

What to do if the differential jumps?

As we have seen, the factors that influence the differential jumping can be many, from a short circuit in the house line until more power is being consumed than contracted.

But it may also be that the sheath protecting the resistance has been perforated and it has come into contact with the water causing a short. This problem can also happen to the thermostat.

In both cases, the solution is to replace the thermostat in one case and the entire thermostat in another, with a new one. If this is the problem, it is best to call a technician again.

Is the water not hot from my thermos?

In this case, the most common is that it is a resistance problem, if the installation is well done. If we have checked the wiring and it is fine but the resistance continues to fail, we will have to replace it with a new one.

It may also be that the water does not heat due to a failure in the thermostat, the thermal safety relay or the thermal probe. Fixing this is not in our power, what it is to do proper maintenance and periodic reviews.

Thermostat light won't come on?

Many times the electric water heater does not work because the thermostat has been turned off. One of the causes may be that it has overheated and the internal thermostat they carry has turned off.

To solve it, you have to find a small slot in the thermostat and insert a thin object until you hear a click. In this way the internal part is reset and, when we return the current to the thermos, it should work again.

If we do this and the light still does not work, the problem is probably more complex and we cannot fix it ourselves.

Is there a water leak?

At this point it must be remembered that the installation of these appliances is not complex but you have to be very meticulous with it, because otherwise these leaks may occur.

This problem can be very simple or very complex, depending on where the leak is. If the leak is produced by the flange, this part will have to be replaced with the resistance and the anode.

If the loss is due to the safety valve, it will be necessary to check the pressure in the water heater because it is surely a problem of excess pressure in the household water. The solution is to install a pressure regulator at home.

If the loss of water occurs in any other area of the water heater, the problem is serious. It is probably caused by corrosion, because the thermos has not been properly maintained. The solution, in this case, is to replace the thermos with a new one.

Is little water coming out of my thermos?

We may tend to think that the electric boiler does not work for this reason, but it is not. Here the important thing is to know how our appliance works and what type it is.

If the problem is not one of temperature but of water flow, the water heater works perfectly and it is most likely that we have a problem with the pressure of the pipes in our home.

Here we will have no choice but to contact a plumber to solve the problem.

Most breakdowns can be prevented by knowing the operation of the appliance and carrying out small periodic checks.

Taking care of our appliances is the best way for them to respond just how we need them and when we need them. A good guide to make our life more comfortable.

The story of the prefabricated diamond begins in the mid-20th century, but in jewelry use, it is only now beginning to raise its profile. Prefabricated or synthetic diamonds have many nicknames, the most common of which are Lab Grown Diamond and Man Made Diamond. At Argyle pink diamonds , we call the synthetic diamonds in our own collection Argyle pink diamonds Man Made diamonds.Pictured is Argyle pink diamonds Man Made pink diamond. It has a carat weight of 0.343 ct and a price of 392 euros. A similar natural diamond would cost about 24,000 euros. What are Argyle  pink diamonds  Man Made diamonds? They are diamonds. They are diamonds in the same way that Koh-i-Noor, who rests in the crown of the Queen of Britain, is a diamond. Does anything distinguish synthetic diamonds from those found in nature? Yes to distinguish, a very strong distinguisher is the origin of the diamond. Argyle pink diamonds Man Made diamonds have not been dug from the ground, but have been made in the factory. Wh


The most common way to process a wooden floor before applying a varnish is to sand it.  It is needed mainly when we want to give it a new image or completely renew it.  Before we start work, however, make sure that the floor is completely hardened and bonded with glue, and then prepare the appropriate tools that will bring the desired effect. What do we polish? Modern belt sanders are used for sanding wooden floor sanding .   Such machines have an endless sanding belt system that rotates on the sanding and guide shaft.  This solution has many advantages, including extended life of the belt, which does not heat up at high temperatures and is equipped with a self-cleaning system during grinding.  Modern belt grinders have built-in suction systems, we call it dust-free grinding technology, they also give great opportunities to adjust the sanding belt and roller pressure.  In turn, angle grinders are used to smooth edges, corners and hard-to-reach surfaces.

How expensive home automation systems differ from cheap ones

The market for home automation systems is strange for a person who does not “cook” in it all the time. Seemingly similar solutions may differ in price by a factor of 10 or more. I'd like to understand where the deception is. Cheap systems do not work, or do they want three prices for expensive ones?The funny thing is that there is no cheating, there is a difference in functions. More precisely, in the details. The market for cheap systems is mainly targeted at the DIY (do it yourself) segment. In these systems, after passing a simple independent training, the future owner of the automated system configures it himself. And he does it most often. Within the limits that the system allows. A person gets the result, he can use the configured  home automation  system (turn on / off the light, control the shut-off valves on the water supply, listen to music and watch movies). Profit!And then the details begin. In order to turn on the light or (oh, miracle!) Change the backlight color, yo
