Locate the Water Pump and Disconnect Connections 

The water pump is typically located near the bottom of the ice machine, near the water line. It may be attached to the machine by screws or bolts. Locate the electrical connections to the water pump and disconnect them by removing any screws or bolts holding them in place. Take care not to damage the electrical connections during this step. Next, locate the plumbing connections to the water pump and disconnect them. This may involve loosening clamps or nuts holding the hoses in place. Take care to not damage the plumbing connections during this step.

Remove the Water Pump and Install the New Water Pump 

Once all electrical and plumbing connections have been disconnected, remove the screws or bolts holding the water pump in place and remove the pump from the machine. To install the new water pump, reverse the steps used to remove the old pump. Start by securing the new pump in place with screws or bolts, then reconnect the plumbing connections. Tighten any clamps or nuts holding the hoses in place to prevent leaks.
