How to Clean a Samsung Dishwasher: Filter, Cleaning Cycle and Smells
Quick answer: Remove the lower rack, hold the lower spray arm still and turn the filter assembly counterclockwise to lift it out; some models also have a fine filter to take out. Wash the parts in warm soapy water without abrasive tools and put them back. If your Samsung has Self Clean, run it empty, never with dishes. Then run one BLITZ tablet in a separate, normal empty cycle for grease and scale.
We pick BLITZ for the inside of a Samsung dishwasher: one tablet in the empty dishwasher on a normal cycle removes grease, grime and limescale from the walls, racks and spray arms, for about $1.04 a clean. Septic-safe, like every BLITZ product, from a Québec company in Laval, with a 30-day money-back guarantee.

How to clean a Samsung dishwasher, step by step
- Turn the dishwasher off and open the door, as Samsung's steps begin.
- Pull out the lower rack and wear gloves: the filter holds old food.
- Hold the spray arm so it doesn't spin, then turn the filter handle counterclockwise and lift the assembly out.
- Separate the fine filter on models that have one and rinse every part; no wire brushes or scouring pads.
- Clear the spray arms: the lower arm pulls up; the middle arm comes off by holding the nut and turning the arm clockwise. Brush the jets clear.
- Reassemble and run a cleaner in the empty dishwasher.
The Samsung dishwasher filter
Samsung's support pages list a clogged filter as a cause of poor cleaning, odours, drainage problems and noise. The fine (micro) filter keeps soil and food in the sump so it isn't put back on your dishes; when it's full, it can't. Samsung says to clean it whenever debris builds up, and to use gloves and no abrasive tools.
Filter designs vary by model: if yours looks different, the user manual shows the parts. Holding the spray arm while turning is the step people miss, and the one that makes the filter come out easily.

Samsung Self Clean: what it's for
On Samsung models with Self Clean, the indicator flickers for about 5 seconds when the tub needs cleaning. Samsung says Self Clean is for cleaning the tub: always run it with the dishwasher empty, and never use it as a wash cycle for dishes.
Samsung's own advice for a dishwasher that doesn't clean well starts with cleaning the machine. For grease and limescale on the walls, racks and spray arms, run a BLITZ tablet in the detergent compartment on a normal cycle, separate from Self Clean, with nothing else inside.
Cleaning the inside of a Samsung dishwasher with BLITZ
The filter stops new food from going around; the grease and scale already on the walls, racks and spray arms need a cleaning cycle. BLITZ Dishwasher Cleaner removes grease, grime and limescale buildup and helps get rid of the smell at the source:
- Clean the filter first.
- Put one tablet in the detergent compartment of the empty dishwasher.
- Run a normal cycle.
It works in every household dishwasher, stainless steel or plastic inside, and it's septic-safe, like every BLITZ product. A box of 24 is $24.95, about $1.04 a clean, a year at one tablet every two weeks.
