Slow water dispensing

It takes 30+ seconds to get 8 oz of water. I change the filter every 6 months. The icemaker seems to be fine. We always have a full bin of ice. We are on city water and do not use a softener or osmosis system. Any suggestions?

It sounds like there is some blockage between the water inlet valve and the dispenser. I would first check to see if the water flow coming out of the water inlet valve is good.
