my FISHER-PAYKEL REFRIGERATOR Model #RX256DT7X1-22600-A water filter leaks at the joint between the filter holding base and the filter. Best I can guess is that the o-rings have collapsed (but they look and feel fine) or since it is a different substitute (a Maytag UKF8001) a supposed equal exchange instead of the Fisher-Paykel no. 13040210 (not locally available and 3 times the money). I tried plumbers grease on the o-rings and tried new o -rings... still leaks. Anybody have any experience with this refrigerator being "brand loyal?" I am actually considering removing this filter altogether and putting on an outboard filter. Any suggestions?
I should add that the refrigerator did not have a filter when we got it and does not have the bypass cap on the filter unit. Otherwise, it runs and looks new. Thanks.
