h20x5 steam cleaner keeps tripping main fuse box?

I had the same problem. The cause was the connecting power wires to the heating element getting damp / wet from a leaking tank. Open it up and check the tank for any leaks, also make sure to clean and dry the heating element incasement and cable connections. I used a small wire brush and a hairdryer and my x5 was back in working order.
