Aside from your oven and refrigerator, your dishwasher has to be one of the most useful kitchen appliances. Although it is often overlooked and underappreciated, few appliances have saved people as much time as the humble dishwasher.

Sometimes, though, a dishwasher flips the script on us and becomes a source of frustration. It refuses to work, and instead of saying what it needs, it just flashes an incomprehensible, cryptic code indicating something is wrong. This form of communication, known as error codes, doesn’t always make sense unless you have a manual handy.

Thankfully, you don’t have to take classes to learn how to speak Dishwasher to figure out what’s gone wrong. All you have to do is keep reading to discover some of the most common Samsung dishwasher error codes and find out what they mean.

Samsung Dishwasher Issues

When it comes to dishwasher issues, some are more common than others. Here are some of the most common dishwasher problems and how you can fix them:

  • Clogged filter: Most dishwashers made before 2010 have self-cleaning filters, but more recent models tend to have a removable filter. Look in your manual for instructions on how to detach and clean the filter to fix this issue.
  • Water temperature issue: Dishwashers usually use water that is around 50 degrees Celsius. Ensure that your water heater is set to the proper temperature to solve this issue. If that doesn’t fix the problem immediately, running your kitchen sink on the maximum heat setting for 30 to 60 seconds may help.
  • Clogged spray arm: Dishwasher spray arms have small jets inside of them. These jets can get clogged with calcium deposits or other materials. Detach the spray arm according to your manual and brush the jets to remove any material. You may need to use a toothpick or small bristled stick to clear out any material inside the jet head.
