Check the water hose mesh filter

The Samsung Washer 4E code in Samsung washing machines can also occur due to dirty water hose mesh filters. This filter is designed to prevent big pieces of debris from getting inside the machine. This isn’t as good as a water filter so little pieces can still make it through. To clean the mesh filter follow these steps:

  • Turn off the water supply.
  • Remove the water hose from the washing machine by rotating it in a counterclockwise direction.
  • Pull out the mesh by using pliers but be gentle.

Kinked water supply hose

Your water pressure should be around 0.5 bar to 8 bar. If the water supply hose is kinked or jammed, then it will prevent water from going into the washer. You can check the water supply hose by following these steps:

  • Turn off the water supply
  • Remove the hose by rotating it counterclockwise.
  • If you see any bents or kink areas, straighten them out.
  • Make the water flow through it to see if there’s any blockage or not.

Broken water inlet valve

Like every other thing, your home appliances also need regular maintenance to work properly. Regular maintenance will help your Samsung washer to work for a long time. You can prevent your Samsung washing machine from any type of error with regular maintenance.

Here are the few steps that will help you with maintenance

Clean your machine regularly

You should regularly clean your machine. Regularly cleaning doesn’t mean everyday, but once or twice in a month is necessary. You can manually clean your Samsung washing machine by running hot water into the drum to remove any molds, debris bacteria or residue. Some Samsung washers have a self clean function that will start to blink after 40 washes on a front-load washing machine while on top-load washing machines it will start to blink after 20 washes.

The self clean will help the washing machine to remove any molds or smells.

Use a water softener system

Some areas have a hard water system and minerals from hard water accumulate and block the water hose. When the water supply hose gets blocked it will lead to your Samsung washer not working properly and the Samsung Washer 4E code will also start to appear because of this. So make sure to install a water softener system so your water hose remains clean.

Clean water supply of home

Make sure your home water supply is clean and is able to provide enough water to the machine to make it work. It also includes setting your water pressure and ensuring your water taps are properly open.

Install your washer properly

When you have done regular maintenance and cleaning, please reinstall the components of your Samsung washing machine properly. Ensure there’s no damage or broken water inlet that will lead to any type of problem.

If you find any type of issues related to an error code then follow the above steps to solve your problem.
