Water does not flow through the heater and boiler: what is the reason, how to fix it - Setafi

Now without it it is difficult to imagine a pleasant shower after a hard day's work, or comfortable washing dishes. It is indispensable where it is simply "impossible to live" without hot water. We are talking about a boiler, or a water heater - a device that is installed in areas without a centralized supply of hot water or where it is frequently turned off.

We will not resort to history and talk about the ancient Greeks, because we all gathered to solve a very important problem - why hot water does not flow well from the boiler. You should not panic right away, because sooner or later every electrical appliance needs maintenance and repair. We will talk about all the reasons for the failure of the water heater and their elimination in the framework of this article.

Water does not flow through the water heater or flows weakly - what are the reasons

If one of the component parts fails, this often leads not only to poor supply of hot liquid, but the flow of water may stop altogether. There are plenty of vulnerabilities, especially if the boiler has not been serviced for a long time. Here are the most popular moments:

Water "stuck" near the filters

Incoming filters are installed in each water heater in order to clean the water from debris and rust. The base is a stainless steel mesh. Over time, any filter that has collected a lot of garbage ceases to function. And if the water has a lot of metal in its composition, you will often have to clean the valves.

How to check the filter? On the side of the boiler there is a special nut that opens access to the grid.

A faulty pressure reducer also prevents fluid flow. Each valve has a moving part on the stem, which moves under the work of the coolant back and forth under the tension of the spring.

The weak spot is the stem entry hole. Salts accumulate on it, settling on the stem and blocking its full-fledged work. The result is that water does not enter the boiler at all.

Blockage inside the tank

Filters can let in small particles, due to which scale and lime deposits form inside the device. Budgetary electric boilers “suffer” with such a problem: all pipes are clogged with scale, and water stops flowing.

You know that the water is too hard - put the heater more expensive, because it is better than constantly changing cheap options.

Tubes clogged

The problem may not be in the boiler itself, but in the hoses that supply water. They have a small diameter and, accordingly, there is a greater possibility of debris entering even before the liquid enters the device. This is typical for the supply of hot water - layers of lime accumulate many times faster.

What to do

To increase the pressure of a hot liquid or adjust the water supply, follow a few tips:

1. Check the cleaning filter by unscrewing the side nut. Then remove the mesh and clean it with a brush.
2. The check valve must be removed and blown in the direction of fluid flow. If it doesn't blow, go to the store for a new one.
3. The pressure reducer also needs to be looked at: unscrew the adjusting screw and observe the changes in the outlet flow. Nothing has changed - remove the entire gearbox and clean it, or immediately buy a new one.
4. You can also check the mixers - it is always useful to clean the filter meshes.
5. The scale in the body is very easy to clean: unscrew the cover and the flange at the bottom of the water heater - access is open.

We hope that these tips will help you get your water heater working. If you have come across other causes and ways to fix the problem, share your knowledge in the comments.
