Fixing Whirlpool front loader washing machine. Error at start of 2nd rinse fill
Many whirlpool washers the lower front panel removes with three  1/4" hex head sheet metal screws.

Remove the panel.

Inside is a tech diagnostics document.

It will tell you to hit any 3 buttons 3 times in sequence -- ABCABCABC  All the lights will turn on.

Press button A

The wash light will blink the error code in 1/2 second pulses, a 2 second pause, a second set of half second pulses a longer pause and will repeat.

In my case the error code was 9 2.

Looking this up in the technical document said 'drain problems, suggested checking a wiring harness, and some connectors, also to check the drain filter.  

Since the multimeter was in the garage, and the filter in front of me, I removed the filter (This will discharge a quart of really gross water. Tilting the washing machine back and putting 2x4's under the legs will reduce this a bunch.  

Inside the debris trap I found a $5, a $10, and a $20 bill, in pieces, along with $13 in change.

Cleaned this out along with a small fur ball, and reassembled.  No problems since.

The problem went away and has come back several times. At this time I suspect that the soap detector is expecting a given reading on a given rinse.  Changing brands of soap, and measuring carefully helps.
