The Cloudy Glass Problem Usually Comes Down to This Filter

Cloudy glasses can come from two very different causes: removable film or permanent etching. Before changing detergent, rinse aid and water-softener settings all at once, start with the dishwasher’s filter and a simple glass test.

Remove and clean the user-accessible filter according to the manual. A loaded filter reduces water circulation and can let fine debris redeposit on glassware. Check that the spray arms can turn freely and that visible spray openings are not blocked by food particles.

Next, look at detergent amount and local water hardness. Too little detergent in hard water can leave mineral film, while too much detergent in softer water can contribute to poor rinsing. Rinse aid can improve water sheeting and drying, but it should be adjusted deliberately rather than maxed out by default.

To distinguish film from etching, try cleaning one cloudy glass by hand using a method appropriate for the glass. If the cloudiness disappears, the dishwasher process or water chemistry is the likely cause. If it remains and the glass surface feels permanently dull, etching may already have occurred and cannot be “washed off” by a repair.

If the dishwasher also leaves food behind, drains poorly or stops mid-cycle, the problem is broader than glass appearance. Read Standing Water in the Dishwasher Tub? Start With the Filter and Dishwasher Panel Gone Silent? Work Through This Before Booking Service.

### Maintenance order
Filter first, loading second, detergent and rinse-aid settings third, water hardness fourth. That sequence avoids changing so many variables that you no longer know which one improved the result.
