1. Check date code to make sure pump is within
warranty period. Date code is the month and the
year.
(Example: 0318 is March of 2018. Date Code is
found on the top of the pump.)
2. Make certain that the power source matches
the pump requirements. This pump has a dual
voltage motor and can run on 115 V or 230 V.
This pump is pre-wired at the factory to run on
115 V.
3. If pump does not run, check the GFI or breaker
panel switch to make it is in full operation.
4. If the pump runs all the time, make sure the
pump has been primed correctly. If pump is not
holding the prime, inspect check valve, foot
valve, and piping, then re-prime.
5. If the pump runs but won’t shut off, check
pressure switch.
