What Causes Samsung Dishwasher NORMAL HEAVY SMART AUTO Lights Flashing
When you see your Samsung dishwasher lights NORMAL – HEAVY – SMART AUTO flashing, you need to refer to the tech sheet on the device to decipher the error code. Samsung dishwasher is a smart appliance that means that in case any component is not working correctly, you can expect to get notifications.
Resolving error codes on the Samsung dishwasher is not hard; slight corrections such as adjusting water supply temperature or correct installation of drain hose should do the trick depending on the error.
· Caution! Before digging into what could be the problem, your attention is getting drawn towards, always be sure to cut off the power supply to the Samsung dishwasher. Testing the power outlet for proper voltage is also wise. And finally, turn off the water supply.
What Does the “Normal” “Smart Auto” and “Heavy” LED Flashing Mean?
So, you start a cycle, hear the water get in, but after a minute, the drain pump kicks on draining everything away before the wash cycle, then you get those NORMAL – HEAVY – SMART AUTO lights flashing? Well, what your Samsung dishwasher is trying to tell you is that there’s a problem with the case break sensor.
So when you got this error code, that means a low-water level error. A Samsung dishwasher has a case break overflow water sensor that monitors the water level and sends activation signals to the drainage pump in case of an overflow, low water level supply, or just a general water supply error.
If your Samsung dishwasher is in good condition, the drain pump shouldn’t kick in right after was filled with water. But if your dishwasher keeps draining out, then it could be due to
· A blocked supply valves
· A broken case sensor or it just dirty inside
· A problematic Flow
How do you fix the low water level error?
1. Clean the Overflow Sensor
You will need a Philipps Screwdriver and a Longnose Pliers. Follow the manufacturer’s standard procedure to get to the overflow sensor.
The overflow sensor has two parts: The case sensor and the flow meter assembly. The flow meter assembly has a little spinning wheel, while the case sensor chamber has a floating piece that moves up and down depending on the water level in the unit.
The case sensor is just a rudimentary system with two exposed electrode prongs such that when water reaches them, the circuit becomes complete, and the draining mechanism is triggered.
But water is not the only thing that could complete the circuit. Residues from corrosion, molds, and hard water can also complete the circuit triggering the error code.
Therefore, in the case that the error code results from a corroded sensor, cleaning the sensor chamber should fix your dishwasher. To access the sensor chamber, use a half-inch drill to make holes near the sensor, taking caution not to damage the sensor electrodes or float piece. Next, use stuff such as alcohol, CLR, q-tips to get rid of hard water sum and mold.
Finally, seal back the chamber using a thick plastic and sealants that can handle high water temperature.
3. Replace Broken Case Sensor
In the case that cleaning the sensor chamber didn’t fix the Oe error code, then probably the case brake sensor is broken, and you have to pony up for a new Over Level Water Sensor. Follow the manufacturer’s guideline to install the new case brake sensor into your system. And if you still get the same problem, replace the flow meter assembly.
A faulty case brake system does not only send overflow water level errors, but you could also get low water level error or water supply error. The hacks mentioned above should be able to fix the failure.
Smart Auto and Heavy LED signaling lights are common on Samsung dishwashers. Customers across the world are reporting frustrations due to the faulty case brake systems. You turn on the cycle, hear the water coming in, then suddenly the drainage pump kicks in, and all the water is gone! Very unfortunate.
If your water is hard, you can expect this failure at some pint down the line unless you use a water softener. And if the sensor chamber is already corroded, open it and give it a blitz as directed above. The good thing with drilling holes to clean the chamber and sealing them back with plastic is the plastic can be removed easily for future cleaning tasks.
And finally, in the case that all the above hacks don’t work, check if the unit is satisfied with the amount of water that is coming in. Leaking valves and drains can trigger the Smart Auto and Heavy lights too. Inspect the recesses of your dishwasher for leaking components. Tighten the water supply line dry the inside of the dishwasher using a paper towel.
