Problem with Rheem 40 GAL ELEC TALL Water Heater 6YR SC 82VH402
Got 5 minutes of hot water then cold. replaced both elements and thermos. still 5 minutes of hot water. power bill increased nearly 400% in 30 days. HELP!!! please.
When the top of the tank is hot the upper thermostat removes power from the upper heating element and transfers the power to the lower thermostat and heating element. If the lower thermostat is defective, then the lower portion of the tank will not be heated and the supply will be greatly reduced. You replaced both elements however check that the lower element is coming on after ther upper one cuts out and is acutally working.
Check for power at the upper thermostat terminals where the power is sent to the lower thermostat and heating element. If there is no power then the upper thermostat should be replaced. If there is power then check for power at the lower heating element. If there is no power at the lower heating element then replace the lower thermostat.
If there is power to the lower heating element then it should be getting hot. If it is not, maybe defective. Another possibility is a broken dip tube. Check for a broken dip tube and replace if necessary.
If the dip tube is broken, the incoming cold liquid can mix with the out going hot liquid and cause it to seem as though you are running out.
