Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Inspect accessible inlet hoses for kinks or crushing.
If the model uses removable inlet screens that the owner’s manual allows the user to inspect, check for obvious debris without dismantling the valve.
Confirm the household water valve is fully open.
Check that the ice bucket and user-removable parts are seated normally.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
