My Whirlpool Calypso model GVW9959KQ has failed (on and off) to have power for the last week. I checked the outlet and power source, which are fine. I unplugged the machine for 5 minutes and it then started, but this pattern continued for the week. NOW, it doesn't start at all. What is the problem?

We just experienced the same problem with the buttons! I just kept pushing all the buttons until it switched over-delicate cycle was actually the one that got it going-what a piece of work this machine is!

This is a control fault. the control sector must be replaced asap.

There's a couple of reasons for the F-01, most common is a bad relay on the main control board. (CCU)
This washer will also flash that code if:
1: Either the back or front access panels are removed while operating, there are ground safety switches that are held closed by the panels.
2: If the power supply outlet is supplying much less than 120V (usually would need to be 112V or less to cause it)
3: If the polarity is incorrect (hot and neutral reversed) at the outlet
4: If there is an open ground at the outlet.
The easiest way to check 3&4 is with a simple plug in outlet tester. I have seen all of these problems throw an F-01, but I would still say 9 out of 10 times you have no option but replacing the CCU. Make sure to double check your manual about the warranty info, as some electronic controls are often covered beyond the 1yr standard warranty. If you're going to replace it yourself, it is accessed by removing the top panel, and is located towards the front, right side of the cabinet, and has a zillion wire harnesses plugged into it. When replacing the board, note that there may be some harness connections available on the board that are not used, mark them as such. Hope this helps.

communication error. changing the MCU. sometimes a bad pump could be the problem

Fl means flood
you either have a bad flood switch or something is in the pump.
the pump is located under the washer
if you where to tip back and remove the 3 5/16 inch screws and look to the very right you will see the pump.
it could be these 2 things and or it could be something in your sump balls. which you would need special tools to gain access to.
let me know if this helps
