WI-FI MODULE ERROR
Cause
Wi-Fi module failure, Main (or Display) PCB failure, or connector loose, or wiring issue.
Solution
Check all connections at door hinge, Main or Display PCB and at the WI-FI Module.
Usually this requires a new WI-FI Module to repair.
Note: Check your individual models Circuit Diagram and location of PCB’s

Power from the Display PCB should be 5Vdc.
Also reading the Tx and Rx (communication Lines) on a good Wi-Fi Module you should see …
SB~GY/RD More than 0Vdc and Less than 5Vdc.
BK~GY/RD More than 0Vdc and Less than 5Vdc.
If you have NO 5Vdc replace the Display PCB.
If the Rx or Tx Lines show 5Vdc replace the Wi-Fi Module.
If the Rx or Tx Lines show 0Vdc and the Display HAS the 5Vdc on those lines you may have a connector or a wiring issue,
including a possible door problem.
Another Wi-Fi configuration you may encounter.
