GE Dishwasher CFE Error Code: Communication Fault Fix

Quick Answer

The GE dishwasher CFE error means the main control board and the UI board have lost communication. This can result from a loose ribbon cable or connector between the two boards, a failed UI board, or a failed main control board. Start by checking the ribbon cable connection at both ends before replacing any boards.

The GE dishwasher CFE error means the main control board and the UI board have lost communication. This can result from a loose ribbon cable or connector between the two boards, a failed UI board, or a failed main control board. Start by checking the ribbon cable connection at both ends before replacing any boards. CFE is distinct from 888 in that 888 is a main board internal fault, while CFE specifically requires two-board communication to fail.

What Does the CFE Code Mean?

CFE is a two-board communication error unique to GE's control architecture. The ribbon cable or wire harness between the main board and UI board is the first physical check before any board replacement.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Ribbon cable or wire harness between boards loose or damaged40%
UI board failed after power surge or age24%
Connector corrosion at either board end22%
Main control board failed and cannot initiate communication14%

Symptoms You May Notice

  • CFE displayed on control panel
  • Control buttons respond but cycle will not start
  • Display works but machine takes no action
  • Buttons intermittently unresponsive

Can you reset a Ge dishwasher to clear the CFE code?

Turn the circuit breaker off for 30 seconds. A communication fault caused by a power glitch may clear with a reset. If CFE returns, a physical connection or board issue is confirmed.

Frequently Asked Questions

Is CFE the same as 888 on a GE dishwasher?
No. 888 is an internal self-diagnostic fault on the main control board. CFE specifically means the main board and the UI board are not communicating with each other. CFE can occur even when the main board is functional if the UI board or the cable between them has failed.
Which board do I replace first for a CFE code?
Replace the UI board (WR55X24055, $80-150) first because it is the lower-cost part and is the more common failure point in communication faults. If CFE persists after the UI board swap, then replace the main control board.
