Pump display shows E08 and speed cannot be adjusted; unit may run at a fixed low speed.

Safety first: Disconnect power before accessing the motor terminal box or control compartment.

• Inspect wiring harness: Locate the AquaJet motor feedback connector between the motor and control board. Ensure it is fully seated and free of corrosion or moisture.
• Check for damage: Look for pinched, cut, or chewed wires along the harness route. Repair or replace damaged sections.
• Reset controller: Restore power and perform a factory reset of the AquaJet controller if the manual provides this option. Reprogram desired speeds.
• Replace sensor or motor: If E08 persists, the internal speed sensor in the motor may have failed. On many AquaJet models this sensor is integrated into the motor assembly and requires motor replacement.
