Are error codes flashing brighter on your Samsung dishwasher than your fairy lights did last Christmas?

Here’s how to reset your Samsung dishwasher:

  1. Switch the dishwasher off
  2. Unplug it
  3. Wait 5 minutes
  4. Plug the dishwasher back in

That being said, resetting might not always fix the issue. We’ve covered other fixes in detail below, but make sure you check your manual too.

Some Samsung dishwasher problems are easy to resolve. Today we’ll focus on the following issues:

  • A dishwasher that won’t start
  • A dishwasher that won’t turn on
  • A dishwasher that won’t drain

Coming up is a list of Samsung dishwasher problems and their fixes. They’ll help you get your dishwasher on the mend so that you can ditch those marigolds for good!

How to Fix a Samsung Dishwasher That Won’t Start

Is your Samsung dishwasher falling at the first hurdle? If it’s having problems starting up, there are a couple of things that could be wrong such as:

  • A damaged door latch. If the latch has suffered damage, the door will not be able to close properly and the dishwasher will not start.
  • Child lock settings are on. If the child lock settings are on, most Samsung dishwashers will show a padlock image on the front panel. With this setting on, you will not be able to start up the dishwasher. It is a safety feature to prevent children from playing with the dishwasher.

How to Fix a Samsung Dishwasher That Won’t Drain

Is your Samsung dishwasher having problems draining the water after a cycle? Then before you start manually draining it with a cup and a bucket, take a look below. Coming up, you’ll find reasons why the water in a dishwasher might stop draining. And most importantly, you’ll find instructions to fix the problem.

  • Blocked drains. If you have blocked drains, it will take the water in the dishwasher a long time to drain. Or it may not drain at all.
  • The drain hose is pinched shut. If the weight of the dishwasher is resting on the drain hose it will not allow water to pass through it.
  • The drain hose is not connected to an air gap. If the drain hose is not connected properly dirty water may drain back into the dishwasher.
  • A bent drain hose. Is your drain hose bent or damaged? Then it will be difficult for the water to drain.
  • The control panel is displaying error codes or flashing lights. Some codes and lights highlight problems with the installation of your drain hose. If your dishwasher does this, you will have to fix the problem with the hose for it to work.

You can fix the issue with your dishwasher by working through the following steps:

Reason Why the Dishwasher Won’t DrainHow to Fix It
Blocked Drains      1. Clear your drains with a drain cleaning product. Or use a natural drain cleaning solution such as baking soda, cider vinegar, and hot water.
2. After running a drain cleaning product through the pipes, run the water in the sink. Does the water descend easily down the pipes? If it does, then the water in the dishwasher should begin to drain too.
The Drain Hose Is Pinched Shut  1. A pinched drain hose is an installation problem. To fix this you should contact your dishwasher installer.
The Drain Hose Is Not Connected to an Air Gap1. To fix this issue, you should contact your dishwasher installer.
A Bent Drain Hose  1. Locate the drain hose.
2. Use your hands to push any kinks or folds out of the hose.
3. If the hose continues to kink it may be too long. In this case, trim the hose down to size. Then reconnect the hose.
The Control Panel Is Displaying Error Codes or Flashing Lights1. Consult your user’s manual. It will show you what to do to fix different error codes and flashing light combinations.
