A white, cloudy film on dishes after a wash is one of the most common dishwasher complaints, and the good news is it's almost always a settings-or-water issue you can fix yourself, not a broken machine. The one thing to rule out is permanent glass etching. Here's how a tech sorts it out, cheapest first.
Hard water leaves behind calcium and magnesium as a chalky white film on glasses and the tub, especially without enough rinse aid.
Check it: Run an empty hot cycle with a cup of white vinegar in a bowl on the top rack (or a dishwasher cleaner). For ongoing hard water, use a rinse aid and consider a dishwasher water-softening additive. This clears most white film.
Rinse aid helps water sheet off dishes so minerals don't dry on as spots and film. An empty dispenser is a top cause of cloudy glasses.
Check it: Fill the rinse-aid dispenser and set it to a higher level. On many machines this fixes filming and spotting immediately.
Excess detergent (or a powder that doesn't dissolve in hard/cold water) leaves a residue film. Old or clumped detergent is worse.
Check it: Use the recommended amount of a fresh detergent (pods meter it for you). Make sure your hot water reaches the dishwasher — run the kitchen tap hot before starting.
A dirty filter or blocked spray-arm holes means dishes aren't rinsed well, so residue and film are left behind.
Check it: Clean the bottom filter in hot soapy water and clear the spray-arm holes with a toothpick. Do the filter monthly.
If the film won't come off even with vinegar, the glass may be permanently etched — micro-pitting from soft water plus too much detergent over time. This is damage, not residue.
Check it: Test one cloudy glass with a vinegar soak: if it clears, it was mineral film (fixable with the steps above); if it stays cloudy, it's etched and permanent. Going forward, cut detergent and use rinse aid to prevent more.
Almost always a free fix — rinse aid, the right detergent amount, a vinegar cycle, and a clean filter solve the vast majority of white film. There's rarely a part to replace. Only permanent etching can't be reversed, and that's a habit change, not a repair.

Almost always hard-water minerals, an empty rinse-aid dispenser, or too much detergent. Fill the rinse aid, use the right amount of fresh detergent, and run an empty hot cycle with a cup of white vinegar to strip existing buildup. Clean the filter too. That clears nearly all white film.
Run an empty cycle with a cup of white vinegar in a bowl on the top rack (or a dishwasher cleaner) to dissolve mineral buildup, and start using rinse aid. For the dishes, a vinegar soak clears mineral film — if it doesn't, the glass is etched (permanent).
Usually no — mineral film and detergent residue wipe or vinegar off. But if a cloudy glass stays cloudy after a vinegar soak, it's etched, which is permanent micro-damage from soft water plus too much detergent. Cutting detergent and using rinse aid prevents more.
