Hello all and regards to Samurai,
Whirlpool Duet Washer WFW8300SW00, new 6/06. Unit was just ruuning fine the other day. I went to use it this morning and its dead. Will not come on with the on/off switch. No lights, nothing. Tested the outlet - is good. Tryed unplugging for 30 sec - no go. I have the L-78 repair manual for this unit. Where do I start?

Thanks
Paul

Hello all and regards to Samurai,
A quick follow up.

I tried to follow the Troubleshooting Guide on page 6-11 of the L-78 manual. I unplugged the unit and removed the top cover. I disconnected the line cord from the power/line filter and checked the cord for continuity. Checks OK. I removed the line/power filter and checked its contacts for continuity. Checks OK. The Troubleshooting Guide says to listen for a click from the CCU when plugged it. I hear NO click. Can I assume its the CCU? I there any other diagnostic tests I should do?

Thanks,
Paul

Hello all and regards to Samurai,
Another quick follow up.

I removed the CCU and opened it up. Right away I could see that one of the large electrolytic capacitors (C21) was bulged and leaking into the plastic housing. Also a small axial inductor (L1) had split open. Im sure they are both NG.

"Roger your plan to go EVA and replace...". Oops, wrong movie.

I can buy the CCA for about $140 locally (can get in 1 day) or online for about $110 shipped. I can try replacing C21 and L1 as the parts will only cost about $2 but I need to order them online and wait for them to come (2-5 days)as there are no electronics components places around (RS is useless). I do need my washer so Im trying to decide.

BTW does Whirlpool publish the schematic to that CCA anywher?

Thanks everyone
Paul

Buy the CCU here; if it doesn't fix it, you can return it for a refund. :thumbsup:

Just a quick follow up. I did try to repair the CCA by replacing the blown capacitors and inductor (parts cost all of $3 including shipping from Digikey) but they just blew again the second I plugged the machine in. Obviously a hard fault on the board's 24V power supply. Im not a EE so the board level troubleshooting ends there. I did buy a new CCA online for about $100 shipped (even got it overnight for standard shipping) and the machine came right on. Ran a few loads today - no problems.

Thanks for the help! Great forum.
Paul
