Worth repairing? On a dishwasher under 6 or 7 years old, yes. On an older one, compare with a new machine.
How to check the error log
On most GE dishwashers, hold Start for 5 seconds with the door open to enter the service menu; on models with a hidden display, press Select Cycle and Start together for 5 seconds. The last error shows on the display. Turn power off at the breaker for 60 seconds to reset the board.
Clear the log after a repair so you can tell whether the fault has really gone.
FAQ
What does 888 mean on the GE Appliances dishwasher?
Control board fault. The board failed its own check. A voltage spike (storm, generator) corrupts a memory register and the code keeps returning after resets because the damage is done. Occasionally it is a wet board from a leak.
Can I fix 888 myself?
DIY difficulty: moderate. Cut power at the breaker for 60 seconds and restart. If 888 or CFE returns, check the door panel and base for signs of water on the board.

888 during startup or during use?
GE Appliances dishwashers report 888 any. That timing is a useful clue when narrowing the cause.
Can I keep using the machine with 888 showing?
Treat it as a stop-using signal: 888 marks a fault that can damage the machine (or worse) if you keep running it. Do the safe first steps below, then stop.
Will 888 clear on its own?
Sometimes. Try the reset and cleaning steps first — they cost nothing and clear the milder cases. A code that returns within a day or two needs the parts fix.
How long does the repair take?
Thirty minutes to an hour if you are comfortable opening the case; budget an afternoon the first time.
