1. Water Pressure: The unit requires a minimum inlet pressure (often 0.1 - 0.5 bar) to trigger the microswitch. Low pressure results in a weak flame and lukewarm water.
2. Limescale Accumulation: In "Hot" mode, the heat exchanger operates at peak temperature. This accelerates limescale buildup in hard water areas. Scale acts as an insulator, preventing heat transfer to the water, leading to the overheating sensor tripping the unit off.
3. Gas Pressure: If the LPG or Natural Gas pressure is low, the unit cannot reach maximum BTU output, capping the "Hot" water temperature.

: On many Bosch ovens, a thermometer symbol illuminates while heating and turns off once the target temperature is reached. Error Codes 12V or 18V brushed motor drill/driver Since "EN153"

Buying Tip

• Cause: The plug is too cold (or the engine is rich).
• Solution: The EN153 Hot is the fix. The longer tip burns off carbon deposits.

1. No hot water: Check the power supply, heating element, and thermostat to ensure that they are functioning correctly.
2. Leaks: Check the system for leaks, ensuring that all connections are secure and that the system is properly sealed.
3. Noise: Check the system for noise, ensuring that the heating element is not causing excessive noise.
4. Corrosion: Check the system for corrosion, ensuring that the anode is not corroded or damaged.
