Pump display shows E06 and motor does not start, sometimes after a power surge or lightning storm

Safety first: Isolate the pump at the main breaker. Do not attempt to run the pump repeatedly with this error.

• Visual inspection: Remove the control cover and inspect the PCB for burnt components, cracked casings, or strong burnt smell.
• Check for external shorts: Disconnect the motor leads from the PCB and any external control wiring. Try powering the controller alone (if allowed by the manual). If E06 remains, the fault is internal.
• Surge protection: Before replacing parts, consider installing a surge protector on the pump circuit to prevent future damage.

Internal drive faults generally require replacement of the entire control PCB or motor‑drive assembly. This is a level‑5 repair and should be performed by a qualified technician or the unit should be replaced.
