Electrolux Epic 6500 SR Hose with Electrical Feed?

This is regarding the Electrolux Epic 6500SR with a power nozzle. Is anyone else having this problem? Have you discovered a fix? My hose has power for the power head integrated into the hose. The power is fed to the power head through a series of pins and connectors embedded in the hose and extension wands. The handle on my hose is overheating. I have disassembled the handle and noticed that one of the junctions is not forming a tight circuit, resulting in a broken circuit and overheating. I am hesitant to order a replacement part...this appears to be a design problem. Ideas???
