Before You Start

Prepare a clean, well-ventilated workspace near the pump area. Relieve pressure and drain the filter according to the manufacturer’s guidance. Never power wash DE fingers while seated in the filter housing, as shards can cause injury or damage. Have replacement fingers on hand in case inspection reveals wear or tears. Allow the parts to dry completely before reassembly.

Step-By-Step: How To Clean DE Filter Fingers

Turn off the pool pump and switch off the power at the disconnect. Lock out and tag the circuit if needed.
Open the filter housing and carefully remove the DE filter fingers without tearing them. Place them on a clean surface.
Inspect each finger for cracks, tears, or deformities. Replace any damaged fingers with the replacement DE filter fingers kit for pool filter fingers.
Rinse the fingers under low-pressure water from a garden hose to remove loose debris. Avoid high pressure that could damage the fingers.
Soak the fingers in a mild cleaning solution aligned with the kit instructions (a gentle degreaser or non-abrasive soap). Let them soak for the recommended time.
Gently scrub each finger with the DE pool filter finger brush or the pool filter cleaning wand with bristles to remove stubborn buildup.
Rinse fingers thoroughly until all cleaning solution is removed and water runs clear. Shake off excess water and allow to air-dry if you have downtime before reassembly.
Inspect seals, gaskets, and the cage for wear. Clean any buildup from the filter housing interior as needed.
Reassemble the DE fingers in the correct order inside the filter housing. Ensure snug fit without forcing components.
Repressurize the system gradually, verify no leaks, and restart the pump. Check pressure gauge for normal operation.
Document the maintenance in your log and schedule the next DE finger cleaning interval based on usage and water clarity.

Keeping a routine that includes careful inspection and timely replacement prevents costly issues and keeps the pool sparkling.

Tips For Best Results

Clean fingers in a shaded area to prevent quick evaporation of cleaning solutions.
Label and organize replacement fingers to quickly identify correct sizes or models for your filter.
Use non-metallic brushes to avoid scratching the plastic surfaces of DE fingers.
Maintain a spare parts kit to minimize downtime during maintenance windows.
Record cleaning dates and gauge readings to optimize maintenance intervals.

Call A Professional

Consult a pool professional if you notice persistent leaks around the filter housing, repeated high pressure after cleaning, or if finger damage seems extensive beyond spot replacements. Stop work and seek assistance if any electrical components appear compromised or if you lack the proper safety equipment.
