Complete selector valve: 1½" or 2"

That's the most common issue with this filter. When the valve acts up—water leaks into the drain during filtration, the lever doesn't lock into position, or there's a leak around the shaft—it's often more cost-effective to replace it entirely rather than going through it piece by piece.

How to Find Out Which One Is Yours: measures the pipe diameter that connects to the valve — 50 mm corresponds to 1½” and 63 mm to 2”. Both are side mounting (on the side of the filter, not on top of it). If your valve is mounted on top of the filter, that's an installation top and does not fall within this range.

Manifold arms: The size should match that of your filter

The collector arms are the slotted “fingers” at the bottom that allow water to pass through and they trap the sand. If sand appears in the pool, this is where the leak is—and the solution depends on the diameter of your FKP:

The number is in the filter label It is determined by measuring the widest part of the garment. And here’s a tip to save you some trouble: at €8.90–18.90 per item, when you open the filter Check all the arms and replace the entire set if it's old—the undamaged pieces are the same age as the broken one.

Cover, gasket, flange, and pressure gauge

Quick Diagnosis: From Symptom to Part

Wash based on load size, not on schedule

Record the pressure on the pressure gauge with the freshly washed filter: That's your reference. When it goes up 0.3–0.5 bar on it, tap wash + rinse.

If, after washing, the pressure does not return to the reference, the bed is saturated: it's time to replace the media (every 4–6 seasons (with the water properly balanced). And if the needle doesn't move or doesn't return to zero, the problem is with the pressure gauge—€31.90 to restore the filter control panel.
