My sincerest apologies for the frustration and inconvenience this has caused. The next step would be to proceed with service.

Same issue, normal use and handle is practically falling off. There's no way to tighten it without dismantling the thing. Extended warranty doesn't cover it. An appliance that cost thousands of dollars shouldn't be falling apart in less than a year. Is the service call free?
