Ice maker is making one block of ice in cube storage tray instead of cubes. Their is no water getting to cube making tray so no cubes are being made. I think the water might be filling the storage tray directly. Could this be a defrost problem?

sounds like the Fill Tube in back of the IceMaker, isn't in the correct position

The fill tube was in the correct position, but the tube had a build of ice around the tube causing the water to flow into storage tray. I had the boss defrost the freezer by shutting it down for a few hours with the doors open. This seemed to fix the problem and the ice maker is working fine. Here is my theory.

The cause of the built up I believe was high water pressure causing the valve to dribble.

The cause of high water pressure was from the expansion of the water in the hot water tank as it heated back to temp.(the hot water tank relief valve also dribbled occasionally)

This was in turn caused by the recent installation of a new water meter on my supply line with back flow valve giving the expanding water no place to go.

My fix also included a temporary relief valve to limit pressure to max 90 psi.

then you'd need an Expansion Tank on the Water Heater (usually) cold inlet line

Shouldn't install a Back-flow Valve without one.
