How to fix Bosch Measuring Instruments when water does not get hot?

  If your Bosch Measuring Instruments water isn't getting hot, first ensure the power supply is on and working. If the indicator light doesn't illuminate, check the high limit reset button. If the light works but the water remains cold, test for a plumbing crossover by shutting off the cold water supply and opening the hot water tap; any continuous flow indicates a crossover. Allow approximately 20 minutes for the water to heat up after filling the appliance. If problems persist, have a qualified technician test the heating element's resistance (8-10 ohms); replace the element if readings are outside this range.

  If you notice brown or rusty water from your Bosch Measuring Instruments, it suggests a 'spent' anode rod and potential tank deterioration. Inspect the tank for any leaks and check the anode rod.

  Smelly water from your Bosch Measuring Instruments could result from a reaction between your local water supply and the heater's anode rod. Check the anode rod. Failure to do so may result in damage to the tank and leaks.

  If your Bosch Measuring Instruments is leaking, inspect the water fittings and the T & P fitting on top of the tank. Remove the front cover and check the heating element gasket. If the tank itself is leaking, contact Bosch Water Heating for a warranty claim if it's still within the warranty period. Also, check the anode rod.
