More
than likely, the thermostat is set too high. Optimal temperature
is 130 degrees. This temperature works well, both for inhibiting
bacterial growth and in reducing scalding injuries, especially to
small children.
Dishwashers
do like a higher temperature; 140 degree+, but they usually preheat
the water to desired temperature, anyway. If your dishwasher doesn't
preheat, then you'll have to go to at least a 140 degrees on your
heater.
Electric
water heaters usually have either two panels screwed to the top
and bottom of the tank or one panel along the side of the tank.
The thermostat is located under these panels. TURN OFF THE POWER.,
remove the plate, using a screwdriver, adjust accordingly.
For
an accurate
hot water temperature reading, first run the water for a few minutes,
then use a thermometer to check the temperature. If it's not 130
degrees, adjust accordingly, wait 24 hours for heater to adjust,
then recheck temperature.
If
the temperature of the water refuses to budge:i.e. adjusting thermostat
has no effect on water temperature, then there is a problem with
the thermostat . Make sure the thermostat is butted right up against
the tank.
Remember
to turn off your water heater when going on vacation to save energy.
