Water is leaking from the clear pump lid area when the pump is running.

Safety first: Turn off power before removing the pump lid.

• Inspect lid and O-ring: Remove the lid and examine the O-ring for cuts, flattening, or chemical damage. Replace if necessary.
• Clean sealing surfaces: Wipe the lid groove and pump housing lip to remove sand or debris that can prevent sealing.
• Lubricate O-ring: Apply a thin coat of pool-safe silicone lubricant to help the O-ring seat properly.
• Reinstall lid: Hand-tighten the lid evenly. Do not use tools that could crack the lid.
