Looks like you're not the first person with this issue that's had the same problem, so I'd say the place to start would be with the other guys who went through it.

In some cases the pressure switch fixed the problem, but there were several other cures that were found by various methods.
Finally, there's a technician's manual on the device page that has troubleshooting steps you can try.
Give that a look and try some of the solutions then come on back and let us know what you found. We find that we can usually learn something from both successes and failures, so be sure to update your question with the results.
