Whirlpool WFW9400SW03 F73 Error

13 posts in this topic

I've recieved an F73 Error the moment I plut this washer in, no other funcion or controls will operate.

 

 

I read that F70-F73 are all the same Heartbear Error.

 

 

Any one experienced in this one?

No , but I would pop the hood and start looking for loose or partially connected plugs on the CCU, MCU, and UI boards...of which there are a crap ton load of.. that is if feel like it. If it is new...I would call for service or take it back as it should be in warranty.

Same MO as the infamous F11 error code. And same solution.

On this machine, a problem with the MCU will give a false user interface heartbeat error. Let's hear it for Whirlpools engineers......

 

or maybe this is another time to deal out a good kick in the 'nads

Try disconnecting the MCU-CCU harness from the MCU and see if the control panel lights up like it wants to run:

Samurai,

 

How are you making those close up photos? They are nice and clear, is this from your smart phone or a digital camera?

If I'm not mistaken, I read once that he does his videos and photos from an iPhone.  Not sure what vintage.

Yes indeed I do get the 3 beeps of death the moment i plug in.  Then F73 on screen,

 

 

i've opened the machine up and have ensured all connections on both control boards are connected. I did try removing the blue cable as well but same beeps and code. i'm going to move onto trying to remove the PCB's and verify ok connections on the boards.

found it, bad connecton not on the CCU or MCU but rather F73 is a bad connection on the front panel control board.

 

 i can see where a technician even tried to repair the connector and put this name on a label.

 

 

ill repair and test

I used to carry a separate camera with me on service calls to take photographs. This particular photo, in fact, was taken with such a separate camera.

Nowadays, however, the iPhone camera is such good quality that I use it for all photographs and videos.

Nice shootin'! Did you happen to get any photographs of the mangled connection?
