WDT970SAHZ0 Whirlpool Dishwasher not drying

The spray bar function stopped working on my dishwasher. I took the unit out, put it on it's side and removed the pump. I disassembled the pump cleaned it, reassembled it put power to it on the bench and it worked. I reinstalled it back in the washer and, reinstalled the machine and the spray bar is working now. But now, the heated wash and heated dry is not working. Can you please help me understand what may have gone wrong?
Run the SERVICE DIAGNOSTICS CYCLE, and let it run all the way through to reset it back to default.

Entry sequence: Press any 3 keys in the sequence 1-2-3, 1-2-3, 1-2-3 with no more than 1 second between key presses. NOTE: Some models have replaced the “Clean” LED with “Completed.”
The Service Diagnostics Cycle will start when the door is closed.

--->Invoking Service Diagnostics clears all status and last run information from memory and restores defaults. It also forces the next cycle to be a sensor calibration cycle.

LET IT RUN ALL THE WAY THROUGH: Service diagnostic cycle will take about 23 minutes.

Do that and see if that resolves the not heating problem.
Hi Jake. I followed the instructions to clear the code yesterday. After that I ran a was cycle and the heat worked. I then went and ran another wash cycle and the heat did not work. I ran the diagnoses function again and I have error codes of F2, F5 and F7.

Yesterday I only had F7 error code before clearing the codes.
