Here are some of the most common water heater problems and possible fixes.
No Hot Water
Possible Causes:
- Tripped circuit breaker
- Faulty thermostat
- Malfunctioning heating element
Solutions:
- Reset the circuit breaker – if the circuit keeps tripping have a certified electrician inspect the system
- Check and replace the thermostat if necessary
- Inspect the heating element. If it is damaged or excessively worn, it should be replaced replacing
Running Out of Hot Water
Possible Causes:
- Undersized water heater for your home’s needs
- Sediment build-up at the bottom
- Malfunctioning dip tube
Solutions:
- Consider upgrading to a larger capacity heater or switching to a tankless water heater
- Draining and flushing the water heater tank will allow the burning to heat more efficiently
- Check and replace the dip tube if damaged – when the tube is malfunctioning cold water will enter at the top of the tank and proper temperature will not be maintained.
Water Discoloration When Running Hot Water
If the water is discolored when running both hot and cold water, there may be an issue with water quality from the well or water utility. Have your home’s water tested to determine the cause.

Solutions:
- Replace the anode rod
- Drain and flush the tank to remove sediment
