Comments about Whirlpool Whirlpool GC1000 Disposer, 1/3 HP Motor, Continuous Feed, Overload Protector:
Unit started making loud clanking sound. I removed the unit and flushed it clean with a hose, rotated the motor with an allen wrench to free it up, turned it on and it still made a loud clanking noise. No refuse was visible inside the unit. Must be an internal part that is broken. Unit cannot be opened to removed loose piece. Unit was just over 1 year old and out of warranty.
