Samsung's troubleshooting table for the DW80B7070 names the causes of film and cloudiness precisely. Soft water and too much detergent leave glasses with a light film: underload the dishwasher and use rinse aid. Aluminum dishes leave marks that need a low-sensitivity cleaner. Coffee and tea leave a yellow or brown film inside the dishwasher, which a spot cleaner or a higher-temperature cycle removes. The Delicate cycle warning matters too: do not use it for ordinary glassware because clouding or etching may occur. Drying spots come from too little rinse aid, so raise the F level from the default F4.
Differential
Likely causes of “Samsung dishwasher leaves spots, film or cloudy glassware”, and how to tell them apart
- 1
Soft water with too much detergent
What separates it There is a light film on glasses after washing because of soft water with too much detergent
How to confirm Use less detergent, underload the dishwasher and use rinse aid
- 2
Aluminum dishes in the load
What separates it There are gray or black marks on other dishes because aluminum dishes are in the load
How to confirm Remove the marks with a low sensitivity cleaner and keep aluminum separate
- 3
Coffee and tea soils
What separates it A yellow or brown film on the tub interior
How to confirm Use a spot cleaner, or a cycle with a higher temperature
- 4
The rinse aid level is too low or the wrong cycle was used
What separates it The glasses are spotty and cloudy after the Delicate cycle because the rinse aid level is too low or the wrong cycle was used
How to confirm Raise the F level and avoid Delicate for ordinary glass
Before you touch a setting
Record this first — changing settings destroys the evidence
- The cycle used and the rinse aid level shown in the settings menu
- Whether the film wipes off or the glass feels rough
- Whether aluminum items, coffee or tea soils were in the load
Try in this order
0 of 5 completedReduce detergent for soft water
ReversibleThe manual says soft water with too much detergent leaves a light film: underload the dishwasher and use a rinse aid to minimize it.
Set the rinse aid level
ReversibleEnter the settings menu by pressing Sanitize and Delay Start together for 3 seconds, press Sanitize until F1 to F6 shows, and use a higher number for better drying or a lower one if dishes look discolored. The factory level is F4.
Handle aluminum and tea stains
ReversibleRemove marks from aluminum dishes with a low-sensitivity cleaner, and remove coffee and tea film with a spot cleaner or a higher-temperature cycle.
Use the right cycle for glassware
ReversibleUse Delicate only for fine glassware and crystal; for other glassware, use Normal. Delicate clouding or etching may occur otherwise.
Clean the tub
ReversibleUse a damp cloth to remove lime scale or grease deposits, or apply some detergent and run an empty cycle using the highest rinse temperature, or use a commercial dishwasher cleaner.
Model-specific
What is true of this model and not of its siblings
- Tools and supplies
- A flashlight, towels, a sponge and warm water, a soft brush for the nozzles, white vinegar for odors and a small level. Samsung tells owners to clean the filter every month and says the dishwasher has electric parts inside, so do not spray water directly onto it; the tools are for the owner checks below.
- Rinse aid handling
- Only liquid rinse aid is allowed; powdered rinse aid clogs the compartment opening. Do not put any detergent in the rinse aid compartment and do not overfill it, because excessive rinse aid may overflow during a cycle. The Rinse Refill indicator lights when the dishwasher runs out.

Stop boundary
When this stops being a self-service repair
- !If glass is permanently cloudy, it is etching and cannot be reversed
- !If film returns with correct detergent and rinse aid in a hard-water home, use a commercial dishwasher cleaner and consider a softener
