refrigerator no water ice only

cant find the problem, indoor water maker started acting up, water dispenser started taking longer to dispense. it was taking up to several minutes then stopped working. changed the filter, checked water flow line from house, both solenoids function, disconnected water line at bottom of door activate dispenser had water flow. if i unscrew water filter housing and dump it and replace dispenser works till you stop it, wait 10 seconds and it wont work till you repeat the filter removal. ice maker has always worked. what else can i check???
