The water pump on the 38 FL is behind the rear panel in the basement storage compartment where the access door is for the water filter.
Our pump will not run unless it is turned on, but it does have two switches, one on the panel in the pantry and one in the docking area where the water hose connects.
If either pump switch is turned on the water pump will run, maybe the outside pump switch is turned on?
