Samsung dishwasher flashing a Normal and Heavy light

Some Samsung dishwashers (actually the old models of this brand) do not have any display to show the troubles and the meaning of those troubles. Instead of a digital display, those dishwashers have blinking light signals.

The combination of those different blinking light signals determines the meaning of a single error. You need to be careful to interpret an error by analyzing the combination of flashing lights.

Although, the dishwasher blinked lights during its regular use. So, the users need to be careful to interpret any error.

Flashing lights will be taken as an error code when the dishwasher is not operational or stops working in the mid of the washing cycle. To fix any error related to your Samsung dishwasher’s heavy and normal light flashing, you just need to make a slight adjustment to get your dishwasher in operation again.

Samsung Dishwasher Flashing a Normal and Heavy light

Samsung Dishwasher Flashing a Normal and Heavy light

In your Samsung dishwasher, there are multiple lights to show you the exact state, operational state, and any error code. So that the users can easily understand the condition of the dishwasher and fix any trouble it has.

Lights can blink in different ways and in different combinations in your Samsung dishwasher.

To identify the error code, you need to consider whether it is flashing heavy or normal light.

Different light flashes have different meanings. Below I am enlisting the common light flashing combination for better understanding.

Normal light flashing

This normal light flashing means your dishwasher’s leak sensor is detecting moisture. Due to this error, your washer will not turn off itself. On that occasion, it will try to drain water from the washer. To solve this issue, inspect the drain hose and water supply line. If you found any leakage, solve it by changing the hose pipe and fittings.

If this normal light is still flashing and there is no leak then follow the below instructions:

  1. If you moved your dishwasher recently, there is a possibility of having some splashed water near the moisture sensor.
  2. Some users install a garbage disposal with their dishwasher. If you do that, make sure you have removed the cap from the garbage disposal.
  3. Make sure that your dishwasher’s detergent dispenser is filled in a manner that has been instructed in the user’s manual. Inspect the outside area of the dispenser and be sure that no extra detergent is there.

If your Samsung dishwasher is still flashing normal light, do not make delay in calling your authorized service provider.

Auto light flashing

It means that water pressure and temperature are not correct. Check the water supply unit and water supply regulator. Be sure that the water supply is turned on.

Please do not use a flood-safe hose as it is inappropriate for your Samsung dishwasher.

Auto and normal light flashing

These two light flashings mean the Samsung dishwasher is too hot. To solve this problem, make an empty dishwasher. After that, add detergent and run in a normal cycle.

If the light flashing is still going on, switch off the main power line off your Samsung dishwasher. Otherwise, you need to call an authorized service provider.

Auto and Heavy light flashing

Auto and heavy light flashing mean too much water inside the dishwasher. This error is related to draining-related issues. To solve this problem, follow the below instructions;

  1. Inspect the drain hose and if any foreign object is found, remove it.
  2. Check the drain hose, and if it is clogged, clean it.
  3. Lastly, clean the drain filter and sump as well as run water to solve this trouble.

Auto and Express 60 light flashing

It means that the dishwasher’s panel detects a stuck button. To troubleshoot this problem, firstly turn off the washer. Then turn it on again and touch every button on the panel. I hope your dishwasher’s auto and express 60 light flashing problems will be solved. Otherwise, contact your service provider.

Auto, Normal, and Express light flashing

This is also the same as auto and expresses 60 light flashing. The washer’s panel has detected a stuck button. Troubleshooting is also the same as the previous one. Firstly turn off the washer. Then turn it on again and touch every button on the panel. I hope your dishwasher’s auto, normal, and express 60 light flashing problems will be solved.

Delicate light flashing

This delicate light flashing means your dishwasher can not drain water. To solve this problem, follow the below instructions;

  1. Inspect the drain hose and if any foreign object is found, remove it.
  2. Check the drain hose and if it is clogged, clean it.
  3. Lastly, clean the drain filter and sump as well as run water to solve this trouble.

Delicate and quick light flashing

This light flashing means that your washer door is not closed properly or the door lock sensor is faulty. Inspect the door lock sensor with a multimeter. If it is faulty, change it to solve the problem.

Express 60 light flashing

Auto light flashing on Samsung dishwashers means that water pressure and temperature are not correct. Check the water supply unit and water supply regulator. Be sure that the water supply is turned on.

Do not use a flood-safe hose as it is not appropriate for your Samsung dishwasher.

Heavy, Delicate, and Quick light flashing

It means your dishwasher has a faulty temperature sensor. To fix this issue, empty the dishwasher, add detergent and run a normal cycle.

If the trouble is not solved, change the temperature sensor.

Heavy and Delicate light flashing

It means the washer’s heater is not working. To fix this trouble, empty the washer first. Then add detergent with it and run a normal wash cycle.

If the lights are still flashing inspect the heater. Change it, if the heater is faulty.

Heavy, Delicate, and Smart Auto light flashing

This flashing light meaning is also the same as Heavy, Delicate, and Quick light flashing. Due to the faulty temperature sensor, these lights are flashing. To fix this issue, empty the dishwasher, add detergent and run a normal cycle.

If the trouble is not solved, change the temperature sensor.

Heavy and Express 60 light flashing

This means your dishwasher is unable to heat inside the washer. This trouble also comes due to the faulty heater. Inspect the heater and change it if it is faulty.

Four or more lights are flashing

The meaning of this signal is that your dishwasher’s control panel cannot communicate with the rest of the dishwasher.

Firstly, switch off your dishwasher and wait for two minutes to solve this problem. Then turn the washer again and hope your trouble will be solved.

If the washer is still flashing four or more lights, need to call your local Samsung service provider to solve the problem.
