Greetings ergoflo13. The PE error is related to the electronic pressure switch or water level sensor. Causes that originate it: 1.-That it is damaged. Possible solution: replace it with a new one unless you change both ceramic capacitors inside and try. 2.-That the terminals are sulfated (dirty). It involves cleaning all terminals involved with that sensor. 3.-Some cable of the three broken. It involves reviewing and correcting the fault. With the help of a tester corroborate that there is continuity in each of the three cables involved. 4.-That from the power card there is no voltage signal between a range of about 2.4 vdc to 5 vdc. The same voltage must reach each ceramic capacitor. That is, between the Violet and White cables as well as between the Orange and White cables the voltage must be the same. If the fault comes from the card either because one of its two resistors is damaged, it will be necessary to contact an electronic technician to replace the damaged resistor. Hopefully, with this and what you have contributed, you will be able to understand and succeed in solving the problem. Thanks and regards.
