LG Dishwasher bE Error Code
Button or touch panel stuck
What this error means
bE is a Button Error—the control thinks a key is continuously pressed. Cycles won't start or may flash bE until the panel state clears.
How BE is detected
BE on LG dishwasher units indicates the drive system did not meet expected performance. Direct-drive washers monitor rotor position with a hall sensor; dryers and dishwashers track motor current draw. When the drum or spray arm fails to turn, the inverter or motor relay shuts down to prevent burned windings. LG LDP7808BD, LG LDP6797ST, and similar variants may show this fault after an overloaded tub or a foreign object jam.
Moisture on touch panel after steam from opening mid-cycle is a leading trigger. Start with dry the control panel with a soft cloth and leave the door open 10 minutes. Rotate the drum or spray arm by hand when powered off—it should move without grinding. Grinding confirms mechanical obstruction; free rotation with repeated BE on light loads suggests hall sensor, motor, or inverter board failure requiring professional diagnosis.
Common causes
- Moisture on touch panel after steam from opening mid-cycle
- Physical debris under a membrane button
- Child pressing buttons during dry cycle
- Failed touch panel flex circuit
Step-by-step fixes
- 1Dry the control panel with a soft cloth and leave the door open 10 minutes
- 2Press each button once to release a possible stuck contact
- 3Turn off breaker power for two minutes
- 4Avoid using cleaners that leave film on touch surfaces
When to call a technician
bE at idle with a dry panel indicates UI board replacement.
Affected models
- LG LDP7808BD
- LG LDP6797ST
- LG LDTS5552S
Prevention & maintenance
- Avoid washing single heavy rugs or shoes that bind the drum; distribute weight evenly to reduce motor strain that precedes BE.
- Record when BE appears in the cycle and whether it clears after a 60-second power reset on your LG dishwasher—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for BE; LG uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting BE; reversed plugs on pumps and valves cause immediate repeat faults.
