Chosen Solution
2021 Whirlpool dishwasher - 15 months old - just past warranty :( parts look just the same as shown here…power surged and then the e2 f2 code started flashing I checked connecting wire continuity - OK replaced user interface (with buttons) board - same F2 E2 error replaced main control - same F2 E2 error repairman proposed same solution… time for new dishwasher!
@indycarl this is tough since we do not know what your repair person checked etc. Usually all you have to do is to: Removed the front panel.Checked 4 pin connector on the P1C connector on both the UI board (thin PCB that interfaces with the buttons) and the main control board (larger control board where all the colored wires interface)On the same connector measure the voltage between pin 2 and 4. It should show ~5V..If there is no voltage replace the main moduleIf there is 5V replace the console. Your DW should be using the W10610059 tech sheet. Just in case you do not have it, get it here W10610059 Tech Sheet W10610059 Rev B
