I started this post. Back then, I ended up buying Sharp (ES-FE710BZ-W) Front Loader washing machine. It's working perfect so far.
It had only one year warranty. I had to claim warranty once for a small problem. But their customer service is pathetic. Their guy charged 500 Rs per visit for his bike's fuel. That shows their mentality very well. Luckily, my machine had a small problem and no parts were needed replacement. I'm afraid they'd charge for that as well. I don't know what kind of warranty is this where you have to pay.
Other than the customer service, the product itself isn't that bad. It has been working quite well for more than one and half a years now.
