Hi Paul. If your clean light blinks 4 times then pauses and blinks 4 more times you have a wash motor error code. The tech sheet explains this error codes as –
4-4 error.
Loose connection in Wash Motor
Circuit and/or open wash motor. 1. Unplug dishwasher or disconnect power.
2. Check all connections in Wash Motor Circuit with meter. Fix/
replace open connection/part.
Motor fuse on control open. Refer to Fuse Service and Diagnostic Checks on Page 1 (next
to Meter Check Diagram). Faulty wash motor drive circuit on
the control.
Faulty wash motor.

I would make sure all your connections are good. Something may have came disconnected at the motor when you were working on the drain pump. The fuse could be bad as well. Your tech sheet should be located on the back side of the toe panel at the bottom of the dishwasher. I hope this was helpful!
