Product review (3 stars): PureWash High Efficiency, Front Loader, Low Flow
After proper installation the unit did not work. No red light or Blue light as indicated. An Electrician determined a bad power cord. I called the company and they were very nice and listened to me. Instead of making me return the entire product for warranty, they simply sent me a new power cord.  Power cord made the unit work. Blue lights indicated everything working properly. But the instructions say that the unit will create bubbles when it is working properly. I did not have any bubbles. I figured out that my Low Flow unit could possibly require low water flow. I started restricting my faucet by about 50% and the unit started making bubbles.  My newer front loader has higher flow than the Low Flow will allow. I now have the unit working properly with low flow water filling my washer slower. I think the High Flow unit would fit my needs better. Bottom line is the company is very easy to work with and the unit is now working properly. If you have a problem, you can speak with a real person.
