Thanks for that Gadge,
I had a look at the video on Caswells site, the 5 step process is quite involved, requiring tank heater, filter pump and a kit of chemicals and more...

Where my cleaner is at: new board and repair parts for the damaged board are on their way.
Why it blew the fuse could have been my fault, I had the tank half full of water, around 4lts plus the basket. The fuse blew when I removed the basket.
I have learned that with out a load in the tank the output current increases making the heat sink hotter.
Should have had the tank full of water.
Does this ring true for anyone?


Happy is he who penetrates the mystery of things.
