I think anything Maytag made with the word Neptune on it is pretty much a problem machine. See if you can clear out the error code. If not, I think it means your main control board has malfunctioned and will need to be replaced, but with unless you can put it in diagnostic mode you will have to replace it on speculation.

Here is a Service Manual

and here is a correction on the service manual, which may be applicable, check your serial number

and here is tech bulletin on a change in the control board which may or may not be applicable in your situation.

Thanks for the post. It does sound like a hairline crack in the connections on the board, almost impossible to find.

Maytag has punted on a lot of problems with various machines.

Thanks again for your post, it is very helpful.

I know this thread is old, but it seems to be helping people still! I see that 20 people have viewed the photo, so there are many of us trying to figure this out. I just finished replacing the drum bearing on the washing machine a month ago and now the hair dryer trick isn't working as well as it used to. (This has been going on for about a year, but only when it's somewhat cold. These units have been a pain, but they're too expensive to give up on!

Tracbulit, can you share with us where you bought that capacitor? I would love to give that a try before replacing the whole control board (which is the only other solution I've seen besides yours. )

Thanks you!!

Had same issues with the 8.8 code - took the control board out and indeed the C15 capacitor had a slight "bump" on it - the previous comment pointing to this as a root cause made troubleshooting a lot easier :)

Replacing the cap fixed the problem.

The C15 cap is a 3300uF (microFarads) and is rated at 16V - the package is 12.5mm (i think). The cap is either an input or an output capacitor for the DC-DC regulator.
Since so many people are having this issue my guess is that the engineers did not choose proper voltage rating or ripple current rating; if doing the repair I would suggest going with a 25 or 35V part of same capacitance in industrial temperature rating of 105 or 125C.
Some parts that will work:
EEU-FC1E392L ; UPW1E392MHD.

Note the direction of the white line on old and new replacement part - they must face same direction while installed on the board.

The whole repair can be done with a cheap soldering iron, flux, and some solder wick for cleaning out mounting holes.

It is worth to note that the 8.8 error is not actually a code - that's why no one knows about it. 8.8 on the display is simply all LED lights being on at once due to low DC voltage going to the main controller on the circuit board - caused in this case by the C15 going bad.

Hope it helps!

Neptune show 8.8 error dryer will not start. Some how I figured out if I press Time Dry button then panel show 40 min then press + button to change time to 41 min then press Start like magic it starts!! then reset panel to sensor setting and reset temperature setting, and Very Dry setting it works have been doing this for about a year now.
