Category: Pool Pump Error Codes

Variable speed pool pumps display error codes when something prevents normal operation. Each code points to a specific fault — not a general failure — and the diagnostic steps are different depending on which code is showing. Ignoring error codes and resetting the pump without addressing the underlying fault usually leads to the same code returning within hours or days.

Error codes vary by brand. Pentair IntelliFlo and IntelliFlo3 use specific numbered codes that indicate drive faults, over-temperature conditions, and communication errors. Hayward EcoStar and MaxFlo VS pumps have their own error display system. Jandy ePump codes tie into the iAqualink control system. This section organizes error codes by brand with the specific diagnosis and repair for each code — so you’re looking at the right information for the pump you actually have rather than generic troubleshooting that may not apply.
