Why is my Bosch Water Heater water not hot?
- DDalton HallJul 25, 2025
If your Bosch Water Heater isn't heating water, first ensure the power supply is on and working. If the indicator light doesn't illuminate, check that the high limit reset button is pushed in. If the light works but the water isn't hot, test for a plumbing crossover by shutting off the cold supply and opening the hot water tap; any continuous flow indicates a crossover that needs correction. As a final step, have a qualified technician test the heating element's resistance (it should be 8-10 ohms); replacement is needed if the readings fall outside this range.
