A clogged or damaged sump filter allows food particles to recirculate in the wash water, leaving debris and film on dishes after every cycle. Replacing the filter restores proper water filtration and cleaning performance.
A blocked sump screen restricts water flow to the drain pump, causing water to drain slowly or pool at the bottom of the tub after the cycle ends. A new filter clears the obstruction and restores normal drainage.
Food debris trapped in a clogged or cracked filter decomposes over time, producing musty or foul odors inside the dishwasher tub. Replacing the filter eliminates the odor source.
A severely restricted sump filter can trigger error codes related to water flow or drainage issues on the control panel. Replacing the filter often resolves these fault codes without further diagnosis.
When the filter mesh is torn or excessively clogged, fine particles pass through and cloud the wash water, leaving a hazy residue on glassware and dishes. A new screen filter restores clean, clear water circulation.
💡 Pro Tip: Is Your Sump Filter the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Dishes come out with food particles or a greasy film even after a full cycle
⚠️ Slow or incomplete draining — standing water visible in the tub after the cycle ends
⚠️ Persistent foul or musty odors coming from inside the dishwasher
⚠️ Error codes related to water flow or drainage appearing on the control panel
Veteran tip: Pull the lower rack, shine a flashlight at the sump screen — if you see visible debris buildup, cracks, or holes in the mesh, replacement is overdue. A clogged filter strains the circulation pump and accelerates wear on other components. Catching it early saves a much more expensive repair down the road.
