Common Samsung Dishwasher Error Codes and Fix Them

1. Error Code 1E: Water Supply Issue

What It Means:
Error code 1E means your dishwasher is having trouble getting water. This can happen if the water supply isn’t working correctly.

How to Fix It:

• Check the Water Supply Valve: The first thing you should do is look at the water supply valve. This is where the water line connects to your dishwasher. Make sure the valve is turned all the way on. If it’s not open fully, the dishwasher won’t get enough water.
• Inspect the Inlet Hose: Next, look at the hose that brings water into the dishwasher. This hose is usually found at the back of the dishwasher. Check if the hose is bent or kinked. A kinked hose can block the water from getting through. Straighten the hose if needed.
• Look for Blockages: Sometimes, debris or dirt can block the water line. Check for any clogs in the water inlet. If you see any debris, clean it out carefully.
• Check Water Pressure: Make sure your home’s water pressure is strong enough. Low water pressure can cause problems with the dishwasher. If you have low pressure, you might need to call a plumber to help with this.
• Inspect the Filter: Some dishwashers have a filter at the water inlet. If this filter is dirty or clogged, it can block water flow. Remove the filter and clean it according to the manufacturer’s instructions.

Error code 1E is usually about water supply problems. By checking the valve, hose, and filter, you can often fix the issue yourself. If these steps don’t help, it might be best to call a professional.

Preventive Maintenance Tips

Taking care of your dishwasher with regular maintenance can help it run smoothly and last longer. Here are some simple tips to keep your Samsung dishwasher in good shape.

Clean the Filter Regularly

The filter in your dishwasher catches food particles and debris. If it gets clogged, your dishwasher won’t clean dishes well. To prevent this, remove the filter and rinse it under water once a week. If it’s very dirty, use a brush to clean it.

Check the Spray Arms

The spray arms help clean your dishes by spraying water. Sometimes, they can get clogged with food or minerals. Inspect them monthly and use a toothpick or a small brush to clear any blockages. This helps ensure water is sprayed evenly over your dishes.

Inspect the Door Seal

The door seal keeps water from leaking out. Over time, it can become worn or dirty. Check the seal every few weeks for any cracks or damage. Wipe it down with a damp cloth to remove any food or detergent build-up. If the seal looks damaged, it may need replacing.

Run the Dishwasher Empty with Vinegar

Running your dishwasher empty with vinegar can help clean the inside and remove any mineral deposits. Once a month, place a cup of white vinegar on the top rack and run a hot water cycle. This helps keep your dishwasher fresh and running efficiently.

Check the Water Supply Hose

The water supply hose connects your dishwasher to your home’s water supply. Regularly check the hose for any signs of wear or leaks. Make sure it is securely connected and not kinked or bent. Replace the hose if you see any damage.

Keep the Dishwasher Clean

Wipe down the inside and outside of your dishwasher regularly. This helps prevent any build-up of grime and keeps it looking new. Use a mild cleaner and a soft cloth to avoid scratching the surfaces.

Following these preventive maintenance tips can help avoid common issues and keep your Samsung dishwasher running smoothly for years.
