Troubleshooting
This list will suggest situations that might cause this symptom.
1. Pump "OFF" - switch Pump on and make sure it primes.
2. Pump too small or worn out - minimum 30 G.P.M. to cause Pressure Switch to close.
(Some 2-speeds will not produce 30 G.P.M., on low speed.)
3. Filter dirty - backwash or clean filter.
4. Incorrect wiring - check Schematic and wire connections.
5. Defective Pressure Switch or something blocking the flow to the switch - bypass Pressure Switch
and or check fitting opening for debris.

The wiring was crossed from
the Switch to the Board and
we used a Breaker (Reset)
that was external to the
Transformer.
