Washer works fine except towards the end of the cycle it stays stuck in final rinse mode showing it has 1 minute left in the cycle and it takes about 20 minutes to finally time out. What could be wrong?
Answer Hello Wizzle,
This sounds like you need to run the diagnostic test. The tech sheet explains this as follows:
Starting the test mode
Close the door.
Press the Control On button.
Select the DRAIN/SPIN cycle.
Select NO SPIN by pressing the SPIN SELECT button, as needed.
Push Prewash Option button four (4) times within five (5) seconds. C:00 will show in the display.
NOTE: If Model does not have PREWASH Mode as an option, press RINSE/HOLD.
If the Starting procedure fails, push PAUSE/CANCEL button. Then repeat the starting sequence.
If fault codes are detected, they will be displayed. This gives you a starting point to troubleshoot from.
When I run the diagnostics, it will flash F then H then goes back to time 002. The CCU seems to be making a hissing noise. When I unplug the CCU it will quit. I do not hear any click like it says I am suppose to hear. I want to make sure it is the CCU before getting one they are costly.
Answer Daedge2, The "FH" error code indicates that the washer isn't filling with water properly or the water level switch is not "tripping" between empty and full. The lack of cold water could be the issue, and causes the diagnostics to stop at the 002 segment of the test mode as well as the hissing noise. When power to the CCU is first established, there may be a "faint" click noise from the board itself. it can be very faint and may not be heard. But the fact that the control can be programmed, tested and display works, tells you the line relay closes and the board operates. You would want to recheck all the diagnostic codes, check the fill valve and water supply to the washer, and the water level switch and air tube, before you replace any other parts.
