Ariston and Termex water heaters have established themselves well in the market. If everything is more or less clear with equipment with a mechanical type of control, then with devices that have a touch differential of control and programming systems, everything is not clear. Errors in the display indicate a malfunction. The main causes of malfunctions are inattention, improper operation and lack of timely maintenance. Some of the problems can be fixed by yourself.
Touch water heater.
Attention! One and the same error of the Termex and Ariston sensor differential of a water heater can have different meanings and methods of elimination.
Water heater errors
The error information below will be given separately for Ariston water heaters, separately for Termex devices.
Errors of the differential touch of the water heater Ariston and their causes:
- E1 is a system error. The control board is malfunctioning. Power surge, condensation has formed on the control board.
- E2 - “dry” inclusion. Turn on the device without water in the tank.
- E3 - short circuit or depressurization of the temperature sensor.
- E4 - the water temperature rose above 90 ° C. The thermostat does not work.
- E10 - malfunction of the temperature sensor.
- E11 - excess temperature (more than 105˚С). Faulty temperature sensors, overheating of the heating element.
- E12 - water temperature is higher by 12 ° C. Faulty temperature sensors, a large amount of precipitation and scale on the heating elements.
- E13 - the difference in readings between the sensors by more than 50 ° C. Sensor differential error, temperature sensor malfunction, dirt in the boiler.
- E14 - slow heating of water. Low voltage, a lot of scale and precipitation in the device.
- E15 - lack of water in the tank. Safety valve tripped.
There are models in which there is no display with letters. Then the causes of malfunctions and remedies must be sought in the operating instructions for this particular model.

Remember! Due to the fact that electronic control units are being upgraded all the time, manufacturers in the operating instructions for different water heaters may not indicate all errors.
Termex water heater errors:
- e1 - there is no water in the boiler;
- e2 - thermostat malfunction;
- e3 - the temperature rose above 85 ° C, the thermal switch tripped;
- Vakum, Over-heat, Demo is lit on the display, the protection has been activated when turned on without water.
In devices of certain series, errors e1, e2, e3 are accompanied by a sound signal and automatic shutdown.

Correction of common mistakes of water heaters
Elimination of common errors of Ariston water heaters:
- E1 - to fix a system error, it is necessary to reboot the control system, turn off the device for 5 - 10 minutes. If the error appears again, inspect and dry the board.
- E2 - before switching on, it is necessary to draw water until a steady stream appears in the tap.
- E3 - diagnose the cause of the malfunction, check the wiring. Replace temperature sensor.
- E4 - in case of malfunction, replace the thermostat.
- E10 - check the integrity of the wiring, the weakness of the contacts. Verify that the temperature sensor is working. Repair the malfunction.
- E11 - replace the temperature sensor. In case of overheating of the heating element, clean the heating element from scale.The storage water heater must be regularly emptied of precipitation. Replace the heater.
- E12 - check the serviceability of sensors, heating elements, drain precipitation, clean it or replace the heating elements.
- E13 - rebooting the control system, diagnostics of temperature sensors and control system boards. Replace if necessary.
- E14 - check the voltage in the network. Get the heater, clean from scale and deposits, drain sediments. Check for serviceability. Perform a replacement.
- E15 - check the presence of water in the water supply, the condition of the safety valve. In the event of a malfunction, replace the part.
Management board
Remember! Independent repair of equipment under warranty entails a complete rejection of the warranty by the manufacturer.
Correction of errors in Termex water heaters:
- e1 - disconnect the device from the network, draw water, turn it on again;
- e2 - replace the thermostat;
- e3 - it is necessary to turn on the thermal switch by pressing a button inside the sensor housing.
There are models with a resettable thermal fuse. After cooling the water in the boiler, he himself will return to working mode. To speed up the process of self-healing, it is necessary to completely change the entire volume of water in the device.
Vakum is lit on the display, Over-heat, Demo is not a breakdown:
- unplug the appliance;
- draw water into the boiler;
- turn on the device;
- on the differential touch, press "^" up and without releasing, press "v" down.
Touch control, no need to push much. If after several attempts nothing happened, look carefully, the inscription “Timer” should be lit. It is necessary to disable the inscription by pressing "<" to the left, then repeat the previous manipulations.
There are other common errors of the Ariston and Termex water heater:
- The touchpad starts flashing and shows strange characters and numbers. Most likely there is no grounding in the boiler. It is necessary to properly ground the device. Reload the boiler.
- Often a protective grounding device is triggered. The reason is a fault in the wiring, an electrical breakdown on the case, a heating element is faulty, a short circuit.
- When connected to the network, the display does not light. Thermal overheat protection tripped. Start the safety thermostat manually or replace in case of malfunction.
Safety thermostat
Caution! Attempts by persons not having the necessary qualifications to eliminate malfunctions associated with electrical wiring and electricity can cause harm to life and health.
- The display of a model that has an antibacterial function should blink when this mode is turned on. If the display does not blink, then the bactericidal element is out of order, it is necessary to contact the service center for a replacement.
- Frequent operation of the thermostat. The temperature is set close to maximum. Reduce the set temperature.
- The time for heating the water has increased. Check the correct temperature settings, the presence of scale and dirt in the water heater. Perform device maintenance.
- The capacity of the water heater has decreased. Inlet valve clogged. Clean the valve, it is recommended to install a filter from mechanical impurities.
Dirt and scale in the water heater
A touch differential is a device that responds to changes in sensor capacitance. Therefore, it is not recommended to press the control buttons with wet hands. Before using the boiler, carefully read the operating instructions for the specific model. If any of the errors reappears, contact the service center.
