Electrolux Cooktop Error Code E40
Communication failure between main touch control and filter board.
Communication failure between main touch control and filter board.
First step from the service manual
1
Verify AC input at the 2 zones induction housing (X50/X52). Verify Lin Bus harness cable from X68/X67 on right side filter board to X20 on the left side filter board. Verify the lin communication wire at the timer input at X4/X5 pin 2.
The complete diagnostic procedure includes additional test steps, resistance specifications, wiring diagram references, and component test points.

Communication failure between main touch
From Service Manual 518311, p.43:
1.Verify AC input at the 2 zones induction housing (X50/X52). Verify Lin Bus harness cable from X68/X67 on right side filter board to X20 on the left side filter board. Verify the lin communication wire at the timer input at X4/X5 pin 2.
2.Inspect the communication harness between the main control and the UI board for bent pins or unseated connectors at each end.
3.Measure supply voltage to the UI board. Expected: 5 VDC at the interface connector; a low or missing rail points back to the main control supply.
