Maybe I'm confused, but if they're willing to do an out-of-warranty repair/fix for a part they later changed due to to problems, I'd say that's GOOD service, not bad, and something I agree companies SHOULD do, but many do not. (Repair known faulty parts, even on out of warranty appliances.) Producing a receipt is a common warranty requirement. Often warranty does not transfer to secondary purchasers, so proving you're the original buyer is a standard, and I'd say, reasonable request. If, for whatever reason, you no longer have such proof of purchase it's possible you'll get them to waive the requirement by giving them more information or explaining the situation again to another rep, calmly and politely. And I know it doesn't help you now, but I've learned (the hard way) to make copies of my purchase receipts for major purchases and store them, along with the product's original instruction manual, in a specific locale for easy potential future access. By the way, we have an LG steam washer and dryer and, knock wood, have so far not needed service. We've been very happy with the quality.

sorry about the yelling..forgot to turn off the caps...LOL. a service person has determined it to be now repairable. The material that came off was not just flakes of enamel. It is a large chunk of blackened on the outside/blue enamel on the inside...leaving bare metal. the flaw is also on the back of the oven cavity...unless I was slinging sugar around by hand it isn't any food item. And causing the enamel to melt and run and form large chunks seems out of the realm of possibility. I looked up on a manufacturers website what could damage the enamel and hydroflouric acid was about it. It is made to be self-cleaning oven...high heat. The interior shouldn't melt with normal cooking of food. And I also know that I "spilled' nothing. If you look closely at the pictures I took, you can see that the damage extends under the edge of the convection fan in the back of the oven...I couldn't have spilled it there.

Sharing a personal experience with LG Customer service. We made the mistake of purchasing LG kitchen appliances 4 years ago. Since the purchase we have had problems with the dishwasher, range, and refrigerator. We were lucky the first two failed appliances failed within the warranty. When our refrigerator stopped working we followed our owners manual. Then called their customer service. Where the individual reading from the script asked the same questions we read on their website. He wanted to dump me quick. I inquired on the built in diagnostics in troubleshooting. His response was just a moment. I then was dealing with a new representative who then tried to sell me an extended warranty for the repair. You are given two options. One year $463 covers parts&labor. Option 2 6 months for $363. I told them I was looking forward to taking their survey. I never got the call back. The last LG appliance for me.

If you need warranty service, your primary contact is the place you bought it from, as they are the party that you have a contract with. A lot of manufacturers offer to step into this responsibility, as they frequently are in a better position to deal with warranty claims. But they can set the terms of this service when they do that. This becomes a problem when manufacturers have a restricted network of authorized dealers. And it's on you to confirm this information or revert back to contacting the dealer instead of the manufacturer. This is a pretty common concept in many jurisdictions around the world, and the US isn't as exception. Amazon throws an extra wrinkle into this whole thing. I believe they might actually be an authorized dealer for Miele. But that's only true if they act in their role as dealer. They also happen to operate a market place where they facilitate third parties selling to customers. In that case, you are most likely dealing with an unauthorized dealer who sources their appliances on the grey market. They might even be customer-returns, or refurbished units. Not surprisingly, Miele is less excited about providing warranty service for these. Can you confirm that you bought directly from Amazon, or was it a third party that happened to sell on Amazon? That's important you know. And yes, if in doubt, Amazon is the best point of contact for you.
