IE error code. Changed inlet valve already and that didn't resolve problem. It continuously fills until the 8 minute alarm. Should I change the pressure sensor? Thank you for your feedback.

In my case, the machine would continue to fill until the internal timer would error out at exactly 8 minutes. After changing the inlet valve and pressure sensor, I have determined that the problem must be with the main board itself. A $200 item. Because the machine is 10 years old, I have decided to move onto a new machine.
