The water in the water heater is slightly warm, or even cold. If the water heater does not heat the water, while a light is on on it, you should worry about its early restoration.
If the listed elements do not work correctly (or if they fail), electric water heaters will not perform their main functions:
Heating element - often fails due to prolonged use.
Anode is a non-corrosive steel rod with a magnesium surface coating. It attracts all the salts in the water. With active use of the water heater, it is recommended to replace the anode at least once a year.
Thermostat is an internal element that controls water heating. In automatic mode, the element compares the current temperature with the user-set one and turns on / off the heating relay.
Insulating gaskets - gaskets between the connecting elements of pipes and a water heater.
Typical causes of malfunction of instantaneous water heaters and boilers include:
poor quality water
error during installation of the device
damage to the electrical wiring
Replacement of heating elements
Replacement of heating elements for water heaters Ariston, Electrolux, Termeks and others is similar, despite the design differences and the different appearance of the devices. The sequence of actions is as follows:
Close the water in the riser, drain the inside of the boiler
Disconnect the power supply to the electrical appliance from the mains
Remove the decorative cover that gives access to the electronic components and check the absence of voltage with an indicator screwdriver.
Remove the terminals and disconnect the wires (in this case, be sure to remember the diagram of their connection). It will not be superfluous to take a picture of the connection diagram.
Do not allow moisture to get on the terminals, contacts and the electronic board of the device in order to avoid a short circuit and its failure.
Having removed the cover and disconnected the wires, take out the heating element.
Check its condition, clean the anode from deposits. The installation of a new element is carried out in the reverse order, while remembering the rules of your own safety in order to avoid electric shock.
Cleaning the heating element
Removing the heating element is carried out in the same way as in the previous paragraph. To clean the surface, use water with a citric acid solution. Please note that there must be enough water so that the element can be completely immersed in it for several days. After that, the remaining limescale can be easily removed with a brush.
Replacing the thermostat
To replace the thermostat, proceed as follows:
Remove the retaining ring (clamping) near the heating element.
Remove the control unit by the sensor and the thermostat itself.
Install a new element. Secure it with the clamping ring.
Check the condition (position) of the safety valve.
The plug heats up when the water heater is running.
Heats up the plug (slight) - allowed during operation. But if it gets too hot, you need to:
Visually check the condition of the tees and extension cords to which the device is connected. Try to choose an extension cord with a large cross-section of wire for fire safety purposes.
Check the condition of the outlet so that the plug of the water heater is firmly seated in the sockets. In some cases, when the plug or socket is loose, the adjacent part of the wire may heat up.
Flow-type water heater does not heat the water.
By the number of instantaneous water heaters, suppliers sell an order of magnitude less than storage electric ones. This is due to increased energy consumption. If you need help with high end water heater repair, call us right now!
