Why is my Ariston AURES TOP 4.5P not heating the water enough?
- RRobert HallAug 6, 2025
If your Ariston Water Heater isn't heating water adequately, try these steps: First, increase the temperature or power setting. Also, ensure the water flow rate isn't too high (over 6L/min) by adjusting the water supply valve. Check the power supply voltage without heating to ensure it's sufficient. Finally, measure the actual voltage while heating to ensure the voltage drop isn't excessive.
