  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.

  An odor in your Bosch Water Heater's water may be due to an unusual reaction between the local water and the heater’s anode rod. Inspect the anode rod, as failure to do so may result in damage to the tank and leaks.

  Brown water from your Bosch Water Heater could indicate a “spent” anode rod and possible deterioration of the tank body. Inspect the tank for leaks and check the anode rod.

  If your Bosch Water Heater is leaking, start by checking the water fittings and the T & P fitting on top of the tank. Then, remove the front cover and inspect the heating element gasket. If the tank itself is leaking and the unit is still under warranty, contact Bosch Water Heating to file a warranty claim. Also, inspect the anode rod.
