Whirlpool f09 e01 and sud error.

[Biglurr54]

I have a Whirlpool WFW95HEDW0 clothes washer.  It keeps throwing sud errors and f09 e01 errors.  I have run a bunch of rinse drain cycles cleaned the dispenser.  Changed the laundry to new laundry multiple runs with no soap and still get the error.  

 

I replaced the CCU, pressure switch, pressure tube, and air trap. 

 

I pulled the pump out cleaned it and inspected the impeller.  It omhed out to 16.2.  

 

I pulled the drain hoses and cleaned and inspected them. 

 

I still am getting the error.  

 

I have too much money into the repairs now but still can't wash my clothes and I don't know what else to try!  

 

Please help!

I believe that’s a long drain error. 
 

Is the pump moving water out at steady rate. Observe it draining. 
 

There’s also a service pointer that could pertain to this issue. It advises the following...
 

Always check the usual causes as outlined in the tech sheet when the washer exhibits the behaviors listed above. If those checks are OK, then inspect the Air Trap Assembly. The Air Trap Assembly attaches to the rear of the Alpha Washer tub. Remove the Air Trap from the Air Trap Hose and inspect the inside of the hose for blockages or obstructions caused by flashing. Inspect by using a flashlight to shine through the hose If a blockage exists, replace the Air Trap Assembly W10626116.
