This post covers how to fix the E02 F08 error, which is caused by the dispenser motor not working properly. If you have an E01 F09 error, read my post about that here. My experience is that the motor is usually fine, but the sensor that detects where the motor has moved the dispenser arm no longer detects the location properly. The fix is to replace the dispenser arm motor assembly, which is Whirlpool part number W10352973.
Here's an amazon link to the part you'll need:
To replace it:
1. Remove the bolts (1/4 inch bolts) on the back of the washer near the top that hold the top on, then slide the top back 1/2 inch or so and lift the front of the top up to remove the whole top.
2. Next look near the back of the dispenser. There are two holes through the metal bracket that let you remove the screws (T-15 Torx screws) holding the motor assembly in place.
3. After removing the screws, pull it off and detach the wires and arm linkage.
4. Reattach the wires and arm linkage to the new part. Then install the part onto the washer, but make sure you slide the tab into the groove on the bottom properly so it doesn't end up like this (oops!).
It was a bit hard to get the screws back into the holes under the metal bracket, but when I put the screws partly into the part and then slid it into the groove it was much easier.
5. Once it's in properly, install the screws, put the top back on, and start enjoying clean clothes once again!
