Hum Not Related to Door
Hi Frigilux,
I am pretty certain that the hum was not related to the door in any way. The hum was constant, even when the drum was not moving. Listening to the sound, it was easily identifed as a motor hum. Compared to a top loader, it was a really quite machine. Comparing it the new generation of front loaders, it was very loud.
I am just curious as I have never been able to confirm with any other Frigidaire front load owner whether their machine had this hum or not. If anyone out there own(ed) the smaller Frigidaire (or Kenmore branded), please let me know if it had a motor hum.
Regarding the boot on the Frigidaire, I agree that the design could have been better. The rubber itself is formed in such a way that it creates an inner ring that will trap, but not release water. If you want to see how the boot can be constructed to avoid this, just look at the Whirlpool, Kenmore or Kitchenaid front loaders. The rubber itself doesn't have any internal trap areas. There is a trap area where the boot unions with the rim of the door way, but a series of weep holes take care of that area.
