Water dispenser spits, sputters or drips after a filter change (purging trapped air)

A new filter or freshly connected line is full of air. Until it is pushed out, water comes out in bursts, looks milky and the dispenser drips as the air expands. The fix is a proper flush in short on/off cycles to the volume the filter maker calls for, usually 1 to 4 gallons. Sputtering that never clears after a full flush points to a mis-seated filter, a restricted supply or a valve problem.

Samsung refrigerators: reading display codes, Cooling Off (demo) mode, and forced defrost (Fd) / test mode concepts

Samsung asks owners not to unplug or press buttons to make a code go away, because that erases what the technician needs; only a few power-related codes are cleared by a 60-second power cut. An OF OF or similar display is Cooling Off (demo) mode, not a fault. The test mode is entered by holding a model-specific pair of buttons until the display blanks, then pressing a button to step through modes, one of which is forced defrost (Fd).

LG appliances: Smart Diagnosis (audible and Wi-Fi), display/demo mode and test-mode concepts

LG's Smart Diagnosis sends the appliance's status to the ThinQ app over Wi-Fi or, on older models, as an audible tone the phone picks up near the appliance speaker; the app then shows the result. A fridge that looks normal but does not cool may simply be in display (demo) mode. LG also has service test modes that run fans, compressor and defrost on command; entry varies by model and should come from the service sheet.

Refrigerator preventive service: condenser coil cleaning, condenser fan and door gasket check

Whirlpool says routine condenser cleaning is often not needed in a normal home but recommends inspecting and cleaning every few months where there is dust, grease or pets; older GE manuals say at least yearly. Many current GE models have a sealed 'NeverClean' condenser that needs no cleaning, and some Whirlpool models can only be cleaned by a technician. Know which design you have before you pull the fridge out. Finish with a gasket and door-seal check.
