The washing washing heater heater is short-circuited or has a wire disconnected. The washing heater in the tub has an error. (Contact error, temperature sensor fault) If the the water water level level sensor operates operates without without water because water is frozen or for any other reason and the temperature sensor engaged at the bottom to prevent overheating for the washing heater detects a temperature of 100 to 150 ˚C, the washing machine turns the input power off. This error occurs when the red temperature temperature sensor at the center of the dry heater operates (at a temperature higher than 145 ˚C) : Corrective action action – Press the button at the center lightly.. The washing machine will operate normally. lightly Alternatively,, replace the temperature sensor if the Alternatively temperature sensing is unstable because of functional degradation. This occurs when the steam function does not not operate normally normally.. This error does not occur in existing drum products. products. Check whether the product is a steam model Heater engagement fault (out of place) The air hose is out of place and water leakage occurs during the spin cycle. The tub back at the safety bolts xing part is broken. Water leakage occurs at the front with foaming foaming because of too much detergent Water leakage occurs because the connecting hose to the detergent drawer is connected incorrectly incorrectly.. The drain drain pump lter cover is engaged engaged incorrectly. incorrectly. Water leakage occurs at the drain hose. The duct condensing holding screws are worn. The nozzle-diaphragm is engaged in the opposite direction or the rubber packaging is omitted. Water leakage occurs because the screws that hold the tub back and front in place are fastened incorrectly. The leakage sensor is faulty faulty..
