| Code | Fault / Diagnostics | Appliances | Action |
|---|---|---|---|
| IF | Icemaker fan Failure / Icemaker fan disconnection, defective PCB, or blockage. Info: An icemaker fan disconnection, a defective Main PCB or an icemaker fan blockage. The appliance has encountered a problem with the fan for the icemaker. | Refrigerator | |
| IS | Icemaker sensor disconnection or short circuit; Icemaker can be blocked as cubes are no longer dispensed Info: Icemaker sensor disconnection or short circuit; Problem with the icemaker. | Refrigerator | |
| It | Icemaker unit Failure / Icemaker unit disconnection, motor/Hall IC damage, or defective PCB. Info: An icemaker unit disconnection, an icemaker unit motor or hall IC damage or a defective Main PCB. The appliance has encountered a problem with the icemaker unit motor. | Refrigerator | |
| LE | Motor overload / Locked Motor Error. Info: Hall sensor, Stator, Rotor magnet cracked or broken, Main PCB, Connector/Harness issues, Motor windings, connector, wiring. | Washing Machine | |
| Lo | Low room temperature (ambient temperature below -10 degrees Celsius). This is a notification to the customer. Info: The appliance has detected that the ambient temperature was below -10 degrees Celsius. | Refrigerator | |
| LED blinking 1 time repeatedly | Service guide LED blinking 1 time repeatedly. Info: PCB part defect (MICOM). 3 Elite Techs Verified | Refrigerator | |
| LED blinking 2 time repeatedly | Service guide LED blinking 2 time repeatedly. Info: PCB part defect (Piston over-operation). | Refrigerator | |
| LED blinking 3 time repeatedly | Service guide LED blinking 3 time repeatedly. Info: Power voltage defect. | Refrigerator | |
| LED blinking 4 time repeatedly | Service guide LED blinking 4 time repeatedly. Info: COMP cable contact error. | Refrigerator | |
| LED blinking 5 time repeatedly | Service guide LED blinking 5 time repeatedly. Info: Piston lock. | Refrigerator | |
| LED blinking 6 time repeatedly | Service guide LED blinking 6 time repeatedly. Info: Circuit over-current error. | Refrigerator | |
| LED blinking 7 time repeatedly | Service guide LED blinking 7 time repeatedly. Info: PCB part defect (IPM). | Refrigerator | |
| LED blinking 8 time repeatedly | Service guide LED blinking 8 time repeatedly. Info: Communication error. | Refrigerator | |
| nP | No heat detected. Check the breaker box, heating element, or thermal fuse. PRO TIP: 'Flow Sense' or restricted airflow errors mean you must clean the vent — this is the #1 fire hazard. | Dryer | |
| OE | Drain problem. Info: Drain hose twisted/frozen, drain pump impeller clogged, connector disconnected/disassembled, drain pump coil cut-off, MAIN PWB ASSEMBLY faulty, drain circuit, its pump, pressure chamber, and pressure switch, electronics. | Washing Machine | |
| PARAMETER ERROR | Voltage interruption during configuration. Info: Voltage interruption during configuration. | Coin/Fee Automat | |
| PE | Pressure sensor error / Water level control problem. Info: Defective pressure switch, or electronic board. | Washing Machine | |
| PF | Power failure / Problem related to the electrical power supply. Info: Problem related to the electrical power supply. | Washing Machine | |
| PS | Power supply issue. Check electric outlet or power cord connections. PRO TIP: 'Flow Sense' or restricted airflow errors mean you must clean the vent — this is the #1 fire hazard. | Dryer | |
| r2 | Refrigerator Sensor 2 problem (lower part) / Refrigerator side temperature detection problem Info: Refrigerator sensor disconnection or short circuit. | Refrigerator | |
| Refrigerator Defrost Heater Error | Refrigerator Defrost Heater Error is displayed. Info: Loose connection (CON4), relay operation issue, open or short of Fuse-M, defective heater, defective DEF-sensor, gasket not stuck or high temperature loads (hot foods) in product, defective main PCB. | Refrigerator | |
| Refrigerator Defrost Sensor Error | Refrigerator Defrost Sensor Error is displayed. Info: Loose connection (CON8), defective D-Sensor, defective main PCB. | Refrigerator | |
