What Our Customers Say
"I am so happy with the services provided by TruePro Home Services! I have a very old oven that I truly believed would need to be replaced. But, Yury came on time, diagnosed the issues, and had the parts with him to do the repair the same day. My oven is now in perfect working order. Highly recommend!"

"Our LG Front Loading washer wasn't draining. I contacted Simon the next day. He had the part on his truck and came by within 30 minutes, and had it up and running super fast! Thank you Simon for your punctuality, honesty and great value. See you next time!"

"Wonderful and top notched care! They were able to meet my same day expectation to get a washer and dryer hooked up in a new house. He was attentive, thoughtful and explained it all as well. I would highly recommend their service!"

What Error Code EE Means
The EE error code means the EEPROM chip on the main control board cannot be read or written to. EEPROM stores your washer's operating parameters, cycle data, and calibration values. The washer cannot function without this data. This is a board-level failure, and the machine will not run any cycle until the board is repaired or replaced.
Common Causes
Corrupted EEPROM data
A power surge, brownout, or unstable voltage corrupts the data stored in the EEPROM chip. The washer cannot load its operating instructions.
Failed EEPROM chip
The physical chip on the control board has reached end of life or suffered electrical damage. It no longer retains data.
Main control board failure
The PCB traces or supporting components around the EEPROM chip have failed, preventing the processor from communicating with the memory.
Power surge damage
A lightning strike or utility power spike sent excess voltage through the board, frying the EEPROM and sometimes other components.
How to Fix It
- 1
Perform a hard reset
Unplug the washer from the wall outlet. Wait a full 5 minutes. This allows all capacitors on the control board to fully discharge. Plug the washer back in and attempt to start a cycle. If the EEPROM data was only temporarily corrupted, the board recovers during power-up.
Unplug the washer before handling any components on or near the control board.

Check for power supply issues
Plug the washer into a surge protector if it is plugged directly into the wall. Check your breaker panel for tripped breakers. Measure the outlet voltage with a multimeter β it should read between 110V and 125V AC. Unstable voltage corrupts EEPROM data.
- 3
Inspect the control board for visible damage
Unplug the washer. Remove the top panel and locate the main control board (usually housed in a plastic enclosure near the top-rear). Open the enclosure and inspect the board for burned components, blackened areas, swollen capacitors, or cracked solder joints. Visible damage confirms the board needs replacement.

Note your model number for parts ordering
The model number is on a sticker inside the door frame or on the back panel. You need this to order the exact replacement control board. LG control boards are model-specific.
When to Call a Professional
Call a technician for the EE error. Control board diagnosis and replacement involves handling sensitive electronics and matching firmware versions. TruePro technicians carry diagnostic tools to confirm the board failure before ordering parts. The $59 diagnostic fee is credited toward the repair, and all board replacements come with a 90-day warranty on parts and labor. CA License #51112.

Estimated Repair Cost
| Option | Estimated Cost |
|---|---|
| DIY (parts only) | $100 - $250 |
| Professional repair | $250 - $475 |
Main control boards for LG washers cost $100-$250 depending on the model. Professional installation adds $100-$200 for labor. TruePro credits the $59 diagnostic toward the total. Board-level repair (resoldering or chip replacement) is sometimes possible for less.
