Low Medium High
Code Meaning Severity Common Symptom
F1-E1 Control Board Error High Pressing start has no effect — the dishwasher does not fill, wash, or drain. View F1-E2 Motor Board Error High The dishwasher fills with water but the spray arms do not spin because the motor is not powered. View F2-E1 User Interface Stuck Low The dishwasher begins a cycle without anyone pressing the start button. View F2-E2 UI Communication Fail Medium The control panel display shows no information or only some indicators are lit. View F3-E1 Water Temp Sensor Fail Medium Water is not being heated to the proper temperature for effective cleaning. View F3-E2 Wash Pump Fault High The dishwasher fills with water but the spray arms do not rotate and no water is sprayed. View F4-E3 Water Fill Timeout Medium The cycle begins but halts before any spray arm activity — dishes remain dry. View F5-E1 Door Switch Failure Low The door is firmly shut but the dishwasher acts as if it is open and refuses to start. View F5-E2 Door Not Closing Medium The door does not stay shut and springs back open after attempting to close. View F6-E1 Water Inlet Valve Fault Medium The cycle begins and the motor eventually runs, but with little or no water in the tub. View F6-E3 Fill Valve Circuit Fault High Water keeps entering the tub beyond the normal fill level — you may hear it overflowing into the base pan. View F6-E4 Flow Meter Error Medium The water level in the tub is either too high or too low because the meter is misreading flow. View F7-E1 Heating Element Fail Medium The drying phase does not generate heat, leaving all dishes wet at the end of the cycle. View F8-E1 Slow Drain Detected Medium After a cycle completes, a pool of water remains in the bottom of the dishwasher tub.

View F9-E1 Drain Pump Issue Medium After a cycle ends, several inches of dirty water remain at the bottom of the dishwasher.
