The most common problems with electric boilers include:
- Water does not heat up: This usually happens due to a burnt resistor or a faulty thermostat. The resistance, which is responsible for heating the water, may be damaged by wear or sediment accumulation, preventing proper functioning. The thermostat, on the other hand, may fail to measure the temperature correctly, so that heating does not occur.
- Water leak: It may be caused by a damaged pressure relief valve, which controls the excess pressure inside the boiler. In addition, it may be the result of wear and tear on the tank due to corrosion or cracks on the internal surface, compromising the integrity of the device.
- Turns off by itself or doesn't turn on: When the boiler doesn't turn on or off on its own, the problem usually lies with the electrical connection. There may be blown fuses, circuit breakers fired, or a thermostat that is not working properly, interrupting the flow of energy and turning off the appliance.
- Corrosion or rust: Over time, the boler tank may wear out due to corrosion. Corrosion occurs when the sacrificial anode, a part that protects the interior of the tank, is not replaced regularly, allowing the tank to begin to rust, which can result in leaks and lower heating efficiency.
-Water heats up little: Another reason may be the insufficient capacity of the boiler to meet the demand for hot water, or even a thermostat that is not measuring the temperature correctly.
