Water Heater Troubleshooting- Too Hot Water Heater Troubleshooting- Too Hot
On occasions you may notice that your hot water is extremely hot which can be dangerous so you may need to resort to water heater troubleshooting to identify why the water is too hot. If very hot water or steam is ejected from the faucet or you can hear boiling water sounds inside the heater, the heater may not be shutting down at its correct temperature setting. The relief valve is meant to release pressure build up at a set temperature or pressure limit. This valve may not be installed correctly or may be faulty. In either case this is dangerous.
Step 1 – Check the Thermostat
Make sure that the power to the heater has been switched off. Remove both lower and upper thermostat panels. Inside the panels is the temperature adjustment control which may be turned to the desired temperature. This should be around 120 degrees, the factory setting.
Step 2 – Let the Water Cool Down
If the temperature control is set at the correct temperature, turn it all the way down. Leave the heater for about 20 to 30 minutes to cool down.
Step 3 – Call a Professional
Because of the combination of electricity and high temperatures, it is advisable to have a qualified professional investigate problems involving water heaters especially pertaining to the pressure relief valve.
