Avalon Self Cleaning Water Cooler

I have had this water cooler for well over 2 years now, no parts have failed. The Unit works as expected. Here is the problem though. Even though this water cooler has the ability to clean itself using ozone, the user is still required to manually clean the internal reservoir every 3 months to get rid of mold that can start growing. That is fine, I don't mind cleaning it but the design of this unit is not engineered in a way so that lay people can easily clean the inside reservoir. It is a a hassle to take it apart and reassemble. There are very thin electrical wires hanging in the way, the tubes a hard to pull off and reconnect, the manual does a poor job of stating where all these parts belong, it is very easy to lose parts if you drop them in the inside. The unit uses non-captive screws that can easily be lost. If this unit was made to be used and cleaned/maintained by lay people, it should have been designed to be easy to dissassemble, taken out and thrown in the dishwasher, and easy to re-assemble. I gave this product a 3 of 5 because it does actually work as advertised, I have owned this for over 2 years and it still heats/cools water without a problem. I would have given it a full 5 starts if I could clean this thing easily. I have also looked into getting this professionally cleaned, Avalon does not have a contract with anyone to clean these units. Also water delivery companies generally only service water coolers bought directly from them, so that does not help.
