Code Meaning Severity Common Symptom

999 Leak detected in base pan High The base pan beneath the tub has collected water from an internal leak. Water may seep out from under the kickplate onto the kitchen floor, or be visible when you pull the dishwasher forward. View C1 Drain cycle exceeded 2 min Medium After the cycle ends or pauses, standing water is visible at the bottom of the dishwasher tub, indicating drainage did not complete. View C2 Total drain time over 7 min Medium The machine halts during a wash or rinse phase and will not continue. Standing water is visible at the bottom of the tub when you open the door. View C3 Dishwasher will not drain High Opening the door reveals a tub filled to or near the door seal level. Water may spill onto the floor. The dishwasher has not removed any wash water. View C4 Dishwasher overfilled High The tub has filled beyond the normal wash level, causing water to push past the door gasket and appear on the kitchen floor in front of or beneath the dishwasher. View C6 Water temperature too low Medium Cold water cannot dissolve grease or activate dishwasher detergent enzymes effectively, leaving a cloudy or greasy film on dishes even after a full wash cycle. View C7 Temp sensor circuit fault High The machine halts during the wash or heat phase and displays C7. It cannot safely control the heating element without a working temperature sensor, so it locks out the cycle entirely. View C8 Detergent dispenser blocked Low Opening the dishwasher after a completed or halted cycle reveals that the detergent cup is still closed or partially open, with the detergent tablet or powder undissolved inside. View H2O Insufficient water supply Medium The dishwasher completed a cycle without enough water to wash effectively. Dishes remain dirty, detergent is found dried and undissolved in the dispenser, and the tub is dry when the cycle ends. View PF Power failure detected Low After a power outage or circuit interruption, the dishwasher restores power and shows "PF" on the display. The cycle it was running has been cancelled — dishes inside are partially washed. View
