You may think that converting a domestic washer to a coin-operated appliance would be a great way to make extra money. However, there are many difficulties in doing this and you may want to reconsider your choice. Economically, you may find that when adding the cost of a conversion kit as well as the supplies needed, it would actually be cheaper to purchase a used commercial machine. Converting a washer to coin operation can be done, but the conversion comes with many difficulties the owner must confront.
Disconnect the machine from any electricity. Unplugging the machine or shutting off the power to that area of the house will protect you from serious injury or even death.
Remove your washer's access panel and find the machine's timer. If you're unsure how to open the access panel, refer to your machine's owner's manual.
Rewire the machine to use the timer that came with the conversion kit after finding your machine's timer. Because there are different brands and types of converters available, there are different ways to do this. Check with the instruction manual that comes with your conversion kit to accomplish this task.
Cover all exposed electrical wiring with electrical tape to insure safety and a secure connection. Electrical tape is pressure sensitive and will provide insulation for your connection.
Replace the access panel on your machine. After plugging your machine back in, perform a test run to insure proper installation as well as to give you a general idea of what your customers should expect.
