When you make the decision to go off grid, you make a conscious decision to reduce your carbon footprint in as many ways as possible. That being said, being off grid doesn’t mean that you have to live a life akin to an 18th Century pioneer.
Dishwashers are a convenience most people enjoy, getting the dishes clean without extreme effort but they are energy and water sucking units in many cases. When you are off grid, conserving these resources is essential for many different reasons.
Fortunately, there are some great portable dishwashing units that use little water and electricity that do a fantastic job in cleaning dishes.

Hand Washing Versus Dishwasher Use
A long-standing debate exists with dishwashers in general. Do they use more water than washing dishes by hand? On average, a built-in dishwasher uses 6 gallons of water per wash cycle. Energy efficient models drop this use to 4 gallons per cycle. Keep in mind there is still the energy to heat the water and run the dishwasher.
Hand washing is really determined by how efficient you use water in the process. An average sink holds anywhere from one to 1.8 gallons of water. This is obviously a rough estimate as some larger farm sinks might hold more volume.
That being said, for the off grid efficient lifestyle, we’ll assume that a small-to-average sized sink is in use. So right off the bat, by filling the sink to soak and scrub dishes, you are using anywhere from one-quarter to fifty percent of the water use in a built-in dishwasher.
Considering the average faucet flows at approximately two gallons per minute, you have less than two minutes to rinse all dishes before exceeding the water use of the dishwasher.
This makes a great conservation case for dishwashers in general since most people spend more time doing the dishes. In fact, some estimates suggest people use up to 27 gallons of water when hand-washing dishes.
A portable dishwasher can further reduce water usage, dropping the water consumption down to 3 gallons of water or less depending on the capacity. So if water accessibility is an issue in your off grid layout, a dishwasher will help you budget and maintain a water load you can afford to use.
Ease of Use With Portable Dishwashers
Portable dishwashers are designed to move as needed. They range in weight depending on the construction and capacity but expect one to weight anywhere from 40 to 60 pounds. These are designed to sit on countertops like a portable microwave or toaster oven. As such, it isn’t going to be moved from the counter to storage like a blender.
Most will connect to the kitchen faucet for easy installation and use. This means while the dishwasher is in use, the faucet will be inaccessible. While this might seem like an inconvenience, it does eliminate the need for confusing and complicated installations.
There are adapters you can buy to that essentially allow you to split the faucet use and maintain a more permanent installation.
The most efficient portable dishwashers are designed to hold six place settings. This helps keep the model energy efficient and works well with off grid daily needs.

- Can a portable dishwasher be connected permanently under the kitchen sink?
Yes. It is possible to modify the connectors and establish a permanent inlet and waste hose. Unless you are accustomed to plumbing details, it might be wise to get a professional plumber to install this. The benefit is you no longer need to utilize the faucet while running the dishwasher, keeping it available for other use.
- What are the disadvantages of a portable dishwasher in off grid environments?
Depending on the location, you may be limited in water availability. This means running the unit may become problematic if you don’t have available water.
Even though the units are smaller and use less water than most traditional size counterparts, they hold less and require more frequent cycle usage. This means that a larger unit designed for efficiency and using only four gallons per cycle is cleaning a lot more dishes per gallon of water use.
Smaller units also don’t hold larger items, which means you will still need to do a fair amount of cleaning by hand, consuming running water as you wash and rinse cooking items.
- Can I mount this somewhere other than my countertop?
If you are dealing with a small kitchen that has limited counter space to begin with, taking up nearly four square feet in the counter top footprint is a lot. You may be able to prevent losing the space by mounting it under a drawer in a cabinet next to the sink.
This would require cutting holes through the back or side of the cabinet to access the sink plumbing and connecting under the sink with more permanent mounts.
Keep in mind that these units are durable but a leak can go unnoticed in a cabinet for longer timeframes thus causing more damage. Explore all options and get a professional plumber to seal all connections if looking to install the unit anywhere other than the countertop.
