Epicattleya Pixie Charm - no bloom!

[laxfan25]

I bought an Epic. Pixie Charm several years ago from Green Acres Orchids in Lansing, MI (we miss you Cindy and Walt!). It had a lovely fragrance, but I have not been able to get it to rebloom. I've had at least six new pseudobulbs since - but not one flower.
During the indoor months it is in a south window with a sheer drape to cut the direct sun. (I believe that the sun in Michigan winters doesn't really qualify as direct sun! ) Summertime it goes outdoors in dappled sun. It seems healthy enough, I feed it regularly and even tried Bloom Booster to try to motivate it.
I'm 10 years into my orchid addiction and I'm wondering if it's time to start weeding out the non-performers and give them to a better home. Thanks for any advice!
