Why does my Pinnacle Products International Heater shut off after igniting and show error code E1?
- MMichael MedinaAug 9, 2025
If your Pinnacle Products International Heater ignites but the main PCB shuts off shortly after, and the lamp flickers displaying an “E1” error, several factors could be responsible. It might be due to incorrect pump pressure, which requires adjustment. Alternatively, a dirty input, output, or lint filter could be the problem, necessitating cleaning or replacement. Other potential causes include a dirty fuel filter (clean or replace), a dirty nozzle (clean or replace), a dirty photocell lens (clean or replace), an improperly installed photocell (adjust position), a defective photocell (replace), or an improper electrical connection between the main PCB and photocell (check wiring connections).
