Why Samsung Dishwasher Blinking Normal Light: Guide

Why Samsung Dishwasher Blinking Normal Light?

Blinking lights on the LCD of your Samsung dishwasher inform you of machine’s status. This might be as straightforward as informing you of where the dishwashing cycle is at or as sophisticated as alerting you to any mistakes. When the “normal” light on your Samsung dishwasher begins to blink, it’s a good idea to check for faults. If you run an empty load, the problem might go away on its own or point to a more serious problem. Why Samsung Dishwasher Blinking Normal Light?

Why Samsung Dishwasher Blinking Normal Light?

Although blinking lights aren’t the best communication method, you can diagnose your dishwasher’s issue with a few quick checks. Learn the cause of the blinking “normal” light on your Samsung dishwasher, how to resolve it, and other fault codes that involve this light by continuing to read.

What To Do When Your Samsung Dishwasher “Normal” Light Blinks: Causes And Solutions

The leak sensor in your Samsung dishwasher detects moisture in your machine when the “normal” light on the appliance starts to blink without any other lights doing the same. This may occur if the dishwasher is moved, the detergent container is overfilled, or the garbage disposal cap is left on (while attached). It’s safe to presume a problem with the equipment if it doesn’t disappear shortly. The dishwasher then continues to run in an attempt to fix the problem by emptying more water.

If you are confident in diagnosing the problem, use an empty cycle when running water to help locate the leak. To avoid unintentional shock, turn off the dishwasher at your breaker box before you begin tinkering.

The following are the most typical causes of dishwasher leaks:

  • blocked drains in sinks
  • broken hoses or seals
  • clogged drain filters or dishwasher nozzles
  • Dishwashers that are not level or have tight cabinet screws are also prone to leaks and blinking “normal” lights.

1. Clogged Sink Drains

In addition to the “normal” light on your Samsung dishwasher flashing, other indicators of clogged sink drains include:

  • Bits of leftover food in the sink
  • offensive odors
  • water that drains slowly
  • gurgling sounds that are depleting

A partially clogged sink may be the source of a dishwashing leak. Commercial drain cleaners can help you attempt to unclog the drain, but more severe blockages need professional assistance. After positioning a bucket beneath the p-trap of your sink, cut the tubing leading to your drain. Reconnect your plumbing after clearing the obstruction from the p-trap or drainpipe. To unclog your sink, get in touch with a plumber if the issue continues.

2. Damaged Seals Or Hoses

If it appears that the problem is not with the sink drain, check your dishwasher’s hoses and seals for damage or loose connections. This comprises the:

  • The dishwasher’s water supply hose
  • Remove the drain hose from the dishwasher.
  • The dishwasher door’s rubber seal is damaged.

Check if any of these sites have any water nearby. Check for moisture around the supply and drain connection even if there isn’t a puddle visible.

While you’re at it, check your water inlet valve. Where the hose attaches to the dishwasher, a malfunctioning inlet valve may let water leak and may harm the wires that connect to the solenoid valve of the dishwasher. To keep all the water and soap inside when washing, your Samsung dishwasher has a rubber gasket attached to the inside of the door. If food gets trapped in the seal, the dishwasher may leak, or the gasket may disintegrate from use over time.

Shut the dishwasher door with a piece of paper if there are no suspicious tears or stuck food inside. Attempt to extract the paper with the door closed, and then carry out the same action on all sides of your Samsung dishwasher. The paper should be held in place even by a seal that is not torn. Should it come out easily, your dishwasher’s gasket needs to be changed.

Additionally, if the black rubber flap under the lid of a Samsung dishwasher is knocked out of place, it will leak. Take off the kick plate to inspect this component, then reattach the flap if needed.


3. Clogged Dishwasher Nozzles Or Drain Filters

Your dishwasher nozzles and drain filter can clog just as quickly as your sink drain. The detected leak code may be activated by this if water sprays wildly in your dishwasher or gathers at the bottom.

Often deep cleaning your drain filter and nozzle is a good idea. Take these apart and tidy up any debris that remains. Your dishwasher will clean better if you soak the nozzle and drain the filter in white vinegar overnight to get rid of any mineral or grime buildup.

4. Unbalanced Dishwasher problem

A multitude of problems might arise from an unbalanced dishwasher, leakage being one of them. An imbalanced dishwasher blinking its standard LED light could be caused by two things:

  • Unlevel dishwasher: An improper installation or placement of a Samsung dishwasher might cause it to become unlevel on the ground. Spaces left between numerous internal components can also arise from this.
  • Loose cabinet screws can lead to an uneven appliance if some of the components of your dishwasher become removed. It can also let water to leak out from the dishwasher’s surrounds, which could eventually cause the regular light to flash.
  • Overloading the dishwasher – Washing too many dishes at once also causes imbalances, which eventually result in leaks and dampness. Food particles can become lodged in the filters if the dishes are not cleaned well enough. Once lodged, it overflows and leaks forth water.
  • Check the legs of your dishwasher to be sure it is level and not slanting back and forth. If you discover that the wetness is caused by loose screws, next carefully tighten all the screws holding your dishwasher in place.The areas where the screws fasten the brackets to the dishwasher and cabinet are among those you should watch out for.
  • Should overloading occur, you must adhere to the loading capacity guidelines provided by the manufacturer by placing dishes in locations that won’t obstruct the filters and allowing enough room between dishes.

What If You Can’t Find Any Leaks Or Moisture?

After trying every one of the highlighted solutions above and still having trouble, you should check the garbage disposal to make sure the cap is off and to make sure you’re not loading the dishwasher too full.

An appliance technician can also assist you in checking it out.

Samsung Dishwasher Blinking Normal Light and Other Error Codes 

All that implies if your dishwasher is beeping just the standard light is that moisture has been found inside the appliance. That indicates a completely other issue, though, if it blinks in tandem with other lights.

The several light combinations that could blink with the “normal” light will be discussed in this part along with their meanings and solutions.

Blinking LED lightsTheir Meanings
Normal + Heavy LightsThe dishwasher thermistor is faulty or malfunctioning.
Normal + Quick LightsThis indicates a high temperature.
Normal + (Quick+) LightsThis indicates an error with water level or a stuck keypad.
Normal + (Quick+) + Smart Auto LightsHigh Dishwasher water temperature.
Normal + Heavy + Quick LightsNot enough water in the dishwasher
Normal + Smart Auto LightsThis indicates that water is too hot for the dishwasher
Normal + Smart Auto + Delicate LightsThis indicates a heater error.
Normal + Heavy + Express 60This indicate that the thermistor has been short-circuited

Normal + (Quick+) Lights

This is a particular combination of the Quick + and Normal lights that suggests a jammed keypad and a water level problem. Examining the water supply valve and making sure every control panel button functions properly can help you resolve this. To be sure none gets trapped, press each one after the other.

Normal and Quick Lights

A high dishwasher temperature is indicated if you see that the Normal light flashes in tandem with the “Quick” light. Make sure the appliance isn’t becoming overly hot above room temperature in order to remedy this. 

Normal + Heavy + Quick Lights 

This suggests that the appliance is not getting enough water. And before you can resolve this problem, make sure the water supply isn’t shut off. The dishwasher should then have enough water provided to it before beginning a regular cycle. (Add some detergent to the regular cycle before starting it.)

Normal + Heavy Lights

Simply said, the dishwasher thermistor is broken or malfunctioning if the heavy light and the regular light are blinking simultaneously. You have to replace the thermistor to make this right.

Normal + Smart Auto + Delicate Lights 

This also suggests an issue with the dishwasher normal heater, which is heating it much more than normal. When this problem arises, you will observe that the appliance is becoming noticeably hotter than typical. All that has to be done is a standard detergent cycle. Sometime the blinking will stop, and if it doesn’t and it gets hotter, you should get in touch with the manufacturer.



Ultimately, fixing a blinking light on a Samsung dishwasher isn’t too challenging. Once you identify the source of any moisture or leaks, you’ve essentially solved the problem. How to self clean Samsung washer?
