Samsung Dishwasher

Washing your dirty dishes has been made more convenient and easy with the invention of dishwashers. Samsung dishwasher is a well-known brand that offers more advanced technology in the dishwashing world.

Samsung Dishwasher Normal Light Blinking

What Does Samsung Dishwasher Normal Light Blinking Mean?

Light combinations on your Samsung dishwasher would mean that there’s something wrong on the device. It is an indication that it is misbehaving properly and needs to be fixed to have a proper function. 

If you see blinking lights on the normal light,  associated with the auto light blinking of your Samsung dishwasher, it means the dishwasher is too hot. But if it is only the “normal” light that is blinking, it means that the dishwasher’s leak sensor detects moisture somewhere in your machine.

Common reasons why a leak would occur is due to the detergent being overfilled, or if you forgot to remove the connected garbage disposal cap. 

Ways To Resolve Normal Light Flashing on Samsung Dishwasher

Some models of Samsung dishwashers have digital displays that would show a code once it experiences some problems. If you own a Samsung dishwasher that doesn’t have digital displays and you notice that there is a flashing normal light, check out some quick repairs that you can perform on your own provided below. 

Check The Sink Drains

When the sink drain is clogged, it can cause moisture build up that will eventually lead into the normal light flashing on your Samsung dishwasher. Aside from that, you will also experience leftover food particles in the sink, foul smell, slow draining water and gurgling noises while draining if you have a clogged sink. 

To avoid leaks on your dishwasher due to clogged sinks, clear the clog using a commercial drain cleaner. If the clog requires a more hands-on solution, put a bucket below your sink’s p-trap and disconnect the pipe from your drain. Look for the clog from the drainpipe or p-trap and remove it before you reconnect  your plumbing. 

Check The Drain Hose And Seals

If you have checked the sink drain and it is free from any clogs, the next thing to do is to verify if there are any damage or poor connections of the dishwasher seals and hoses. That includes the water supply hose to the dishwasher, drain hose away from the dishwasher and rubber seal around the dishwasher door. 

Check these areas for any indication of water leak. Even if you don’t see any spills, feel around the supply and drain connection for any moisture. While doing this, check the water inlet valve as well. Water will leak where the hose connects to the dishwasher from the water supply once the inlet valve is faulty. If that happens, it can damage wires connected to the dishwasher’s solenoid valve.

Inside of the door of your Samsung dishwasher is a rubber gasket that aims to keep all the water and soap inside while washing. If the gasket is clogged with food debris, it can cause leakage. Also check this rubber gasket if it has not been damaged and deteriorated due to time and use.

If there are no spills or stuck debris, get a piece of paper and shut it in the door of your dishwasher. Repeat this process on all sides of the dishwasher. If you are able to pull the paper without any issues, the gasket of your dishwasher needs to be replaced. You might also need to check if you have a black rubber flap under the door of your dishwasher as this could leak once it is knocked out of place. But if your Samsung dishwasher model doesn’t have it, that’s fine. 

Just replace any damaged or compromised parts of the dishwasher. Once done, test if the normal light is still blinking or flashing by running a normal cycle on the dishwasher. 

Verify If Dishwasher Nozzles Or Drain Filters Are Clogged

Your sink drain may not have any clogs, but the dishwasher nozzles and drain filter might have a different situation. If these things get clogged, the water may spray out of control in your dishwasher or collect at the bottom, which will lead to the detected leak code or normal light blinking.

To avoid this as the cause of the normal light flashing on your Samsung dishwasher, clean the filters and nozzles regularly. To do that, remove these parts on your appliance and clear them of any leftover mess. Others would soak the nozzle and drain filter in white vinegar overnight as it helps in removing  any mineral or grime buildup. If that’s not a problem for you, you can follow it as well. 

For those with models of Samsung dishwashers that do not have a removable filter, try to deep clean the bottom of your dishwasher tub to remove as much debris as possible. 

Check For Improper Installation

Improperly installed dishwashers will cause several problems to occur. A normal light blinking can be an indication of unlevelled dishwasher or tight cabinet screws as they may cause leakage. You will know that you have an improper installation if you notice visual crookedness of installation, racks that roll in or out on their own or gaps between dishwasher components. 

For a leveling issue, you can easily fix it  by adjusting the dishwasher legs higher or lower using a spirit level to verify the correct alignment for your dishwasher. If you have no idea on how to do it or can’t do it at all, call a professional to address the issue.

If you see tight cabinet screws that cause gaps between certain dishwasher components, loosen them up by using a screwdriver. This might decrease the gaps and fix the blinking normal light on the dishwasher. But getting professional help from an authorized technician is still recommended.

You may reach them through their official website, social media accounts like Facebook Messenger and Twitter or by calling them.

  1. What Are Some Other Combinations Of Lights On Samsung Dishwashers And How To Deal Them?

    Aside from the normal light, other lights flashing may also occur. When your dishwasher illuminates both the “auto” and “normal” lights, it’s using water that is too hot for proper operation. The best way to resolve this is to empty the dishwasher and add detergent, and then run a normal cycle. If the error still occurs, switch off power to the dishwasher at the circuit breaker.

    Other light combinations include Auto and Express 60, which means the panel detects a stuck button. For this matter, you may turn off the dishwasher and touch every button on the panel. Auto, Normal, and Express 60 flashing together also means there is a stuck button. 

    You might also encounter Auto and Heavy lights flashing that means there is too much water in the dishwasher. This is often related to a drain issue and can be fixed by inspecting the dishwasher’s drain connection at the sink, checking the drain hose, running water in the sink that the dishwasher is connected to and cleaning the drain, filter, and sump in the tub.

    If it’s only the Auto light flashing, it means  the water pressure or temperature is not correct. You will need to confirm the water pressure and see if the temperature meets the water supply requirements. You will also need to check if the water supply is turned on. Be reminded as well that floodsafe hoses are not compatible with Samsung dishwashers and should not be used.

    There are few other light combinations that might appear on your dishwasher. The best way to find the definition of the light combination and possible solutions is to refer to the user’s guide that comes along when you purchase your dishwasher.

  3. How do I Fix a Heavy Flashing Light on my Samsung Dishwasher?

    If there is a heavy flashing light on your dishwasher, it means there is too much water in the dishwasher.

Run water in the sink that the dishwasher is connected to and clean the drain, filter, and sump in the tub.
