How to understand that the time has come for cleaning?

Installing a hot water boiler is half the battle. It is important to ensure regular care. Tap water, abundant in calcium, magnesium, and other inclusions, is hard. The salts contained in the tap water settle on the boiler parts and interfere with its normal functioning.

Important! If you neglect the cleaning, then the water heater will sooner or later fail. You will have to buy a new boiler, and this purchase is far from cheap.

To understand that it’s time to clean the water heater, pay attention to the following points:

• Water began to heat more slowly than before.
• The device switches off spontaneously, and then turns on again. This is a very formidable sign, a signal for immediate cleaning of the device from the resulting scale.
• The device emits abnormal sounds during operation. This is evidence that some of its parts are not working properly.
• Water acquired an odor and an uncharacteristic dark shade.
• If you have been using the boiler for more than 1-1.5 years, you need to clean it, even if the water heater is fully operational.

Important! Before cleaning the Ariston boiler, be sure to study its device and circuit, since the device will have to be disassembled.

How to prepare for work?

1. To begin, disconnect the device from the power supply. In no case should you work with a water heater connected to the network, as this can cause a short circuit. Therefore, do not forget to turn off the boiler and disconnect the wires that lead to the thermostat.
2. The next stage of preparation is a complete drain of water. Without this, cleaning will not succeed. Attach a hose or suitable diameter pipe to the water discharge pipe. Now open the hot water tap by lowering the hose into the bathtub or toilet bowl first.
3. If the device does not have a safety valve, be sure to turn off the cold water supply. In the future, the safety valve will need to be installed. Blow into the tube to check if water is completely discharged from the tank. If gurgling is heard, then there is still water.
4. Remove the device from the wall by unscrewing the fixing bolts. In order not to stain or damage the flooring, lay old unnecessary rags under the water heater.

How to disassemble a boiler?

To clean the Ariston water heater from scale at home, it must be removed and disassembled. Here's how to do it:

1. Unscrew the fasteners and remove the front panel. It is easiest to clean it from contamination (it is enough to wipe the dust).
2. Directly under the panel is the thermostat. Pull its handle towards you - it detaches easily.
3. Remove the protective cover by unscrewing the fixing bolts.
4. Disconnect the ground wires, then disconnect the thermostat plate.
5. Remove the heating flange.
6. Remove the rubber gasket.

In fact, the disassembly process can be considered completely completed.

How to descale Ariston water heater: detailed instructions

First of all, the tank is to be cleaned of scale, because it always contains tap water with salts dissolved in it, so the appearance of scale is inevitable. Next, clean the heating element.

Important! The magnesium anode should not be cleaned.

For work you will need:

• Soft textile.
• descaling agent.
• Hose.
• Abrasive coated sponge.
• Water.

Descaling the tank is easy:

1. Remove significant impurities manually.
2. Use a hose to flush the tank. The water pressure is medium.
3. Then moisten a soft rag in a solution of descaler and wipe the tank from the inside.

After the tank cleaning is completed, proceed to work with the heating element:

• To clean the heater, you need to use a sponge with an abrasive.
• Some people advise using a knife, but this is not advisable. Of course, you will clear the scale, but the risk of damage to the part is quite large.

If the heater is not only contaminated, but also damaged, its cleaning loses all meaning. You need to buy a new heating element and install it on the tank.

Important! When purchasing a new heater, make sure that the characteristics of the part match the old one.

As already mentioned, you do not need to clean the magnesium anode - the working life is 1 year, so it just needs to be replaced. The price of this item is low, so this procedure can not be called expensive.

Cleaning is complete. It remains only to reassemble the boiler and connect it to the electricity and water networks.

Boiler assembly

The boiler must be assembled in the reverse order of disassembly. After the boiler is assembled, do not forget to check the water heater for leaks. Fill the tank with water and soak for 24 hours. If it does not leak, it means - you did everything right.

The efficiency of its work depends on how responsibly you approach cleaning the boiler. If you are not sure of your own knowledge and skills, it is better to contact the master.

Important! When disassembling a boiler, be sure to photograph the process or shoot on video. In this case, the assembly will be much less time-consuming.

Alternative without disassembly

You can use folk remedies for cleaning the device. Some of them (for example, table vinegar or citric acid) work no worse than professional remedies. In this case, the solution is simply poured into the container, located there from 2 to 12 hours, and then washed. But care must be taken, since too concentrated a solution can corrode the walls of the boiler.

Important! Focus on the proportion of 5 g of citric acid powder per 1 liter of water being poured.

Special scale solvents

In this case, you also do not have to disassemble anything, which is very important if the equipment is still under warranty. You can apply such professional tools:

• AlphaPhos;
• Thermagent Active;
• Cillit ZN / I;
• Cillit FFW / TW;
• Aipacon.

Stock footage

The frequency of cleaning the Ariston boiler is 50 liters - once a year and a half. Do not forget to pay attention to preventive measures. Install a water filter; do not use the device at full power. Heating water to a temperature of 60 to 75 degrees is enough. If you follow all these recommendations, then you will not have problems with water-heating equipment.
