I am beginning to think I might come out cheaper by hand washing (GROAN! LOL).
We have a new energy star dishwasher, but a normal cycle takes 2 hours to run. I do not use the heated dry option.
We have well water so no water bill to worry about (at our old house we had city water so we had a usage fee and then a sewer fee that was based on usage, so every drop of water you used really made a difference on running that bill up).
It seems all I would be running up bill wise by hand washing would be a bit of electric (to heat the water - electric water heater - and to run the well pump........... both of those things would come into play with the dishwasher as well, but it just really seems like I could hand wash cheaper).

Is it cheaper to wash dishes by hand?
Sometimes it is cheaper to wash dishes by hand, but often using a dishwasher can be more efficient. The answer depends mostly on your washing habits. Typically, 85-90% of dishwasher energy consumption comes from heating water. If you use less hot water by hand washing then you are saving energy by doing so. Dishwashers generally use about 10 gallons of hot water per wash on the regular setting. Keep in mind that when you wash dishes by hand you usually use a mix of hot and cold water so that 10 gallons in a dishwasher compares to about 15 gallons of total water hand washing. If you leave the water running while washing dishes then 15 gallons gets used pretty quickly, probably in about 5-7 minutes. However, by filling a double basin sink, using one for washing and one for rinsing, it is easy to use less than 15 gallons and conserve energy.
What is the booster heater switch/energy saver switch on my dishwasher?
Most dishwashers have a booster heater that heats water to the 140oF that is generally recommended for complete cleaning. If your water heater is already delivering water at this temperature then you can turn off the heater. It is more efficient to lower your water heater temperature, 120oF is usually adequate for all other purposes, and use the booster heater for the additional temperature required.
