Display shows 33E; water dispenser or ice maker may not work properly, and you may hear clicking near the water line.

Safety first: Unplug the refrigerator before accessing the rear or hinge area.

Step 1 – Check for frozen water line:

• Try dispensing water; if no water comes out but you hear the valve click, the line may be frozen.
• Open the refrigerator door and feel along the door water line area for cold spots.

Step 2 – Thaw the water line (if frozen):

• Turn off and unplug the refrigerator.
• Leave doors open and allow the line to thaw naturally, or use a hair dryer on low around the dispenser area, keeping it moving and away from plastic parts.

Step 3 – Inspect the water valve heater (if equipped):

• Remove the rear lower access panel.
• Locate the Water Inlet Valve and any attached heater or heater wiring.
• Check for damaged or disconnected wires.

Step 4 – Replace faulty components:

• If the heater is open or damaged, replace the Water Line Heater or the Water Inlet Valve Assembly as designed for your model.

Note: If 33E persists after thawing and component replacement, the Main PCB may not be powering the heater correctly and should be checked by a technician.
