He does this himself (he's a strong guy) so you're not paying extra for helper. He is busy so you may have to wait a few weeks. Hint: he leaves the thermostat at factory setting which is low for our dish washer - ask him to set it a bit higher to at least 140 degrees.

To clarify, most dishwashers have their own heating element and they are designed to operate using 120 degree water. The dishwasher heats up the water to between 140 and 155 during operation. A water heater setting of 140 degrees is way too high for most people. While a setting of 120 degrees may be a little low, a more appropriate setting may be 125 to 130. The last time I checked, the builder sets the water heater to 125 for new houses. To set the water temperature on a dual element electric water heater, remove the two metal cover plates on the water heater, and use a regular screw driver to adjust the temperature on each of the two elements. Both elements should be set at the same temperature. Be careful removing the plates because they have sharp edges.
