Sometimes the Samsung dishwasher presents issues and alerts the user through messages on its display.
The Samsung dishwasher smart auto blinking has a specific meaning. However, “auto” shows up in many instances. Let’s check what is happening.
Depending on which auto message is blinking on your Samsung dishwasher, the solution could be as simple as unsticking the buttons on the panel. However, other messages might require you to unclog several components or replace the thermal fuse or drain impeller.
Below we will discuss the meaning of each message on your Samsung dishwasher’s display.
Samsung Dishwasher Smart Auto Blinking – What It Means
Samsung dishwashers have plenty of convenient features. Such appliances got smarter to follow suit with other devices we have.
However, they also glitch sometimes. Is your Samsung dishwasher blinking smart auto and heavy or some other message?
Let’s learn the meaning of each message:
✅ Auto and Express 60
This alert emitted by Samsung dishwashers has to do with a stuck button. Normal and express 60 signal the same issue.
✅ Auto and Heavy
Perhaps the dishwasher cannot drain all the water, or it has been filled with more than necessary.
✅ Auto and Normal
Sometimes, the warm water inside the dishwasher will get hot beyond the ideal. That can damage the dishes and the appliance.
Dishwashers are sensitive to water pressure because low water pressure means your dishes won’t be cleaned properly, and too much pressure might damage the sprayer arms.
How To Fix Samsung Dishwasher Smart Auto Blinking
Now you have learned all the meanings behind the alerts of your Samsung dishwasher.
Knowing the cause of the Samsung dishwasher blinking smart auto makes it very easy to proceed to the correct solution in the guide below.
In addition, we will help you with the step-by-step method if any component requires replacement.
1. Fix A Stuck Button
If your dishwasher has had a lot of use already, it might start getting buttons stuck sometimes.
Here is what Samsung recommends you do when that happens:
- Turn the dishwasher off;
- Press each button and determine which is stuck;
- Keep pressing them to ensure they unstuck;
- Turn on the dishwasher again.
The error message should be gone. If it is not, you must check for dirt on the control panel. Clean thoroughly so that no dirt can get under the buttons.
Note: If the buttons remain stuck and the message is not gone, the control panel might be defective. Is the dishwasher under warranty? Then call Samsung because the control panel is not cheap.
2. Unclog The Drainage Components
The “Auto and Heavy” message generally means there is some issue with the dishwasher’s draining capabilities. There are many steps you can take to fix that.
- Find the drain connection at the sink;
- Detach it;
- Look for signs of clog inside;
- Detach any hoses too;
- Clean them, eliminate all dirt and debris;
- Run water in the sink.
Wash The Filter
Cleaning the filter that’s inside the dishwasher is of utter importance.
Here is how you can do it:
- Locate the filter;
- Twist it so it will unlock;
- Remove any removable components;
- Rinse them under water;
- Use vinegar and bicarbonate if necessary.
Once everything is dry, reattach it to the dishwasher. Then, run a cleaning cycle with vinegar on the dispenser.
Clean The Air Gap And The Check Valve
The air gap and the check valve are two other components that could get clogged with debris.
You might want to do this:
- Locate the parts;
- Disassemble them;
- Inspect if they are functional;
- Clean all dirt from them.
Once all the parts responsible for your dishwasher’s draining are clean, you must try turning it on again.
Tip: Close the water valve a bit after you clean the components. That way, the strong water pressure will not damage the dishwasher.
3. Examine The Drain Impeller
The drain impeller or drain pump is responsible for the strength to pull the water out of the dishwasher.
It might become weak, which will make the draining take longer. Or it could also fail, making it impossible to drain the water out.
Here is how you can inspect it:
- Place the machine on a flat surface;
- Locate the drain impeller at the base of the appliance (close to the motor);
- Remove the screw or clip keeping the component in place;
- Remove the drain impeller.
Test With A Multimeter
To ensure that the drain impeller is at fault, it is necessary to use a multimeter.
- Set to continuity;
- Test both terminals at the same time;
- The correct reading should be 200 ohms.
Any different reading indicates that you must replace the component.
How To Install The Impeller
When you remove the damaged drain impeller, ensure you don’t damage any of the appliance’s wires.
Then, use the old part as a guide to buy the new one, which must have an identical layout.
- Put the replacement part;
- Remember to secure it;
- Reattach the wires;
- Put the dishwasher back in place;
It is finally time to test if the dishwasher can work fine.
4. Check The Thermal Fuse
The thermal fuse is designed to cut off power to the heating element if the temperature exceeds a certain limit, preventing damage or fire hazards.
However, suppose the thermal fuse malfunctions or becomes faulty.
In that case, it can fail to interrupt the power supply when necessary, leading to excessive heat buildup in the dishwasher.
- Unplug the dishwasher to avoid accidents;
- Disassemble the control panel;
- Look for a small cylindrical device with two wires;
- That’s the thermal fuse.
Test The Fuse
You must use a multimeter to ensure the thermal fuse is truly defective.
- Set the multimeter to the continuity or ohms setting;
- Touch the probes to the two ends of the thermal fuse;
The correct reading should be “0” or close to it.
Replace The Fuse
Thermal fuses are very easy to find. You just need to be careful when installing.
- Disconnect the two wires connected to the piece;
- Remove the fuse from the dishwasher;
- Put the new thermal fuse in place;
- Connect the wires;
- Reassemble the control panel;
- Secure it with screws;
- Reconnect the power supply.
Next, test the dishwasher.
Note: If the dishwasher says there is a temperature issue but the thermal fuse is fine, the problem could lie in the heating element.
5. Adjust The Pressure
Finally, one of the messages on your Samsung Dishwasher means that the water pressure is not ideal.
That could either mean that the water pressure is weak or too strong. Both are undesirable, so let’s see how you can manage the situation.
- Locate the water supply valve behind the dishwasher;
- If it’s partially closed, turn it counterclockwise to open it;
- If it is already fully open, do the opposite;
- See if the message is gone;
If the message persists, do the following:
- Disconnect the dishwasher from the power source;
- Remove the inlet hose from the back of the dishwasher;
- Inspect it for kinks or clogs;
- Clean the hose;
- Clean the inlet filter for any debris or blockages
- Clean the spray arms.
Cleaning the components as instructed above will help the water flow better. That way, the water pressure will be strong enough so the sprayer arms can wash all the dishes.
Alert: It is possible that, after cleaning the components, the pressure will be too strong. Then, close the water valve. Otherwise, you could damage the internal hoses or the sprayer arms.
What We Learned
Are you bothered by the Samsung dishwasher smart auto blinking? You definitely should! That is an alert to tell you that something is wrong.
Fortunately, fixing the dishwasher and getting rid of the alert is not difficult. We hope that your dishwasher is fine by now.
