Low Medium High

Code Meaning Severity Common Symptom

AE Leak Detected High A puddle or wet area on the floor at the front or sides of the dishwasher base, appearing during or after a wash cycle. View BE Excessive suds detected Low Thick white foam fills the bottom of the tub and may be visible through the door window — a clear sign that non-dishwasher soap or too much detergent was introduced into the wash cycle. View CE Motor Current Error High The dishwasher abruptly stops mid-cycle with no warning sound — the inverter controller cuts motor power instantly when overcurrent is detected. View E1 Base Flood Sensor High Water seeping from beneath the kick plate onto the kitchen floor, or discoloration and warping of hardwood or vinyl flooring in front of the unit. View FE Fill Error / Overflow High The water level inside the tub is unusually high — you may see water near the door gasket or even seeping out when the door is opened. View HE Heater Error Medium Without adequate heat, dishwasher detergent does not activate fully, leaving a greasy or powdery film on dishes and glassware. View IE Water Inlet Error Medium The tub remains empty or barely fills during the fill phase of the wash cycle before the error trips. View LE Motor Locked Error High The machine goes silent during the wash phase — no spray arm sound, no water circulation — before displaying the LE code. View NE Vario spray arm motor fault Medium Because the Vario motor is stuck in one position, water is directed only to one zone — dishes in the zone not receiving water will remain unwashed or poorly rinsed regardless of cycle selection. View OE Drain Error Medium Water remains pooled at the bottom of the dishwasher tub after the cycle ends or is interrupted. View PF Power failure during cycle Low A power interruption mid-cycle leaves the dishwasher silent and dark; when power is restored the unit powers back on but does not resume the cycle automatically. View TE Thermistor Error Medium The dishwasher may run the heater continuously or not at all because the control board cannot get a reliable temperature reading from the faulty thermistor. View
