The upper rack was removed for cleaning and I can’t get it back in properly. Please note this rack does NOT have rollers, but is simply a slide mechanism. When I get the rack in place, it only slides out about 1/3 of the way.
Couldn’t find your exact model number, but maybe this video will help. Could it be in backwards?
