Since purchasing this unit in August of 2012 we have experienced significant accumulations of lint at the exterior vent cover which does open and close freely and in the walls of the dryer unit beyond the lint trap which is cleaned after every load. We are cleaning the exterior vent cap at least three times yearly.
Close examination of the area where the dryer lint trap is installed reveals that there is a large gap on each side of the fitting in to which the lint trap screen is inserted which allows vented air to bypass the lint trap mechanism. Lint then enters the vetting system, builds up in the immediate dryer wall area and accumulates on the exterior vent cap. We have never experienced this issue with any previous dryer. It appears to be a design flaw and I am wondering what we can do to eliminate this lint bypass issue. I have attached a link to a picture of the area I believe is the problem.
The area allowing lint bypass of the screen system is the dark triangular area in the upper left corner of the side perforated panel. It would appear that air is to pass through the peforations and lint is not but this open triangular area allows lint to bypass the collector.
