The icemaker will stop when the water level in the Reservoir falls below the lower
float level and is not refilled to the upper float level within 90 seconds due to either an
interruption in the water supply or low water pressure. When the water reaches the
upper float level, the icemaker will automatically resume the icemaking process.
