LG says slow dispensing usually comes from low household pressure or restricted flow. A loaded filter can cause the restriction, but the exact cartridge must match the full refrigerator model.
Start diagnosisClumped ice in an LG GML844 bin can stop the auger and dispenser even when the ice maker is producing normally.
Start diagnosisLG codes E FF and E rF identify freezer or refrigerator fan trouble, often after frost prevents a fan from turning.
Start diagnosisWater around the LG GML844 ice maker can come from a partly open ice-room door, melting ice or an active fill leak.
Start diagnosisLG refrigerators: Overfilled bins, a dirty or displaced gasket and an unlevel cabinet can leave the door sensor unsatisfied even when the door looks closed. Reorganise door bins, clean and reseat the gasket by hand and check level; if the alarm persists with a true seal, request LG service.
Start diagnosisCO indicates lost communication between the main control and display, not a cooling-setting error. Photograph the code, unplug once for five minutes and reconnect; if CO returns, request LG service without opening a panel.
Start diagnosisCF identifies the condenser or mechanical-room fan path rather than the freezer fan or a dirty water filter. Keep the rear clearance open, note any abnormal heat or noise and use the one five-minute reset; recurring CF needs LG service.
Start diagnosisIF points to the ice-maker fan path and must not be merged with the IS sensor or It motor codes. Record IF, protect food if cooling weakens and try one five-minute power reset; if it returns, contact LG rather than forcing the fan.
Start diagnosisFS is the freezer temperature-sensor path, distinct from the refrigerator sensor rS and defrost sensor dS. Note FS, minimise door openings and perform one five-minute reset; if it remains, protect frozen food and arrange LG service.
Start diagnosisrS identifies the fresh-food temperature sensor, not the freezer sensor FS or a door-alarm condition. Record rS, keep the door closed and reset power once for five minutes; recurring rS requires LG service, not a thermostat guess.
Start diagnosisdS identifies the defrost sensor circuit and is separate from dH, where the defrost cycle failed to complete. Photograph dS and use one five-minute reset; if the code returns, arrange LG service without removing freezer panels.
Start diagnosisThese displays share LG's defrost-failure path: frost or a heater, fuse or sensor fault prevented the cycle from finishing. After securing food, put towels down and unplug with doors open for at least 12 hours; never add heat, and use LG service if the code returns.
Start diagnosisIS identifies the ice-maker temperature sensor and is not the IF fan or It motor diagnostic. Copy IS, switch the ice maker off if available and perform one five-minute reset; a returning code needs LG service.
Start diagnosisIt points to the ice-maker motor path, which is separate from a frozen ice bin or low household water pressure. Record It, stop repeated dispense attempts and reset once for five minutes; if it returns, contact LG without forcing the mechanism.
Start diagnosisFU means the freezer cycle is not reaching its expected cooling result, rather than a door alarm alone. Confirm both doors seal and vents are clear, then use one five-minute reset; protect food and request LG service if FU returns.
Start diagnosisrT is the ambient-temperature sensor diagnostic, not the refrigerator-compartment rS sensor. Note room conditions and the exact rT display, then reset once for five minutes; a persistent code requires LG service.
Start diagnosisLG uses HI above 50°C and Lo below −10°C for the ambient reading; neither is the food-compartment temperature. Remove heat sources or restore a normal operating room, then check again; if HI or Lo remains in temperate conditions, contact LG.
Start diagnosisAn illuminated Control Lock deliberately disables the GML844PZKV dispenser and does not prove a valve or pump failure. Hold the Lock control for three seconds until its indicator clears, close the door fully and test one glass of water.
Start diagnosisA hum means the dispenser is calling for water; LG's next checks are the household valve and a visibly kinked supply line. Open the supply valve fully and straighten only accessible tubing without crushing it; stop and close the valve if a connection leaks.
Start diagnosisIf there is no hum, LG first checks whether the door sensor recognises closure; the interior lights should switch off. Remove anything blocking the door, close it and observe the lights without bypassing the sensor; if they stay on or dispensing remains silent, contact LG.
