Samsung washing machine error HE1

error NOT1 Error HE1 in a Samsung washing machine is quite common and can appear at any stage of the “home assistant” operation. There are not very many reasons for it, but they all pose a great danger, and if the control module stops the washing machine by producing a similar error, it actually saves your property from serious damage. How this error is interpreted, what malfunction can cause it and how to eliminate this malfunction, read about all this in this article.

First, let's decipher

If we are talking about the self-diagnosis system of Samsung washing machines, then we can say with confidence that any code starting with the English letter “H” indicates problems with the heating element, and subsequent letters and numbers specify the type of problem. In our case, HE1 literally means that the water in the tank heats up by more than 40⁰C in 2 minutes. What is it about? The heating element heats up too quickly, and it does this regardless of the algorithms that are included in the washing program.

If in such a situation the self-diagnosis system does not stop heating the water, the heating element will soon bring it to a boil and burn, simultaneously damaging delicate items that you may have put in the washing drum.

Error HE1 makes the technician think that the heating element is working, there is no open circuit, but something is causing it to work incorrectly. This is an advantage of the three-digit codes of the self-diagnosis system of Samsung washing machines; they convey information about the breakdown more accurately than two-digit codes, allowing the technician to save time on troubleshooting.

You don't need to look far for an example.Samsung washing machines with a two-digit self-diagnosis code have error H2, which means a breakdown of the heating system. What kind of breakdown is this, what is its nature, just guess. You won't understand until you open the washer. The three-digit code allows you to search for breakdowns purposefully, by the way, about breakdowns.

Possible reasons for the appearance

If you see error code HE1 on the display of your washing machine, get ready to troubleshoot the problem, since this is definitely not a power surge or a short-term electronics failure. What failures cause the HE1 error? There are two such breakdowns: when the temperature sensor fails and when the control board breaks.

The temperature sensor sends information about the heating of the heating element. Using this sensor, the control module can regulate the temperature of the heating element according to the washing program. If the temperature sensor breaks, then the control module is deprived of the ability to control the operation of the heating element and by default, after turning on the Samsung washing machine, it begins to heat up to maximum. In this case, the control module, not receiving information from the temperature sensor for several minutes, urgently turns off the heating element and displays error HE1, stopping the operation of the washing machine.

The temperature sensor of a Samsung washing machine is often installed directly on the heating element, so it will not be difficult to find it. True, you still need to get to the heating element itself, but you can figure it out.

Failures of the temperature sensors of a Samsung washing machine are quite common, but sometimes such a sensor has nothing to do with it. What then is the reason for the error? In such a situation, the cause of the error lies in the control module itself.If a track or triac that controls a heating element burns out, this also leads to error HE1, but the repair is much more difficult and expensive.

Eliminating the causes

As a rule, it is impossible to repair a temperature sensor - it needs to be replaced, but to make sure that the part is faulty, you need to check it with a multimeter, and only then replace it. To check and replace the temperature sensor, you will have to remove the front wall of the Samsung washing machine. How to disassemble the front part of a washing machine of this brand is described in detail in the article. How to repair a Samsung washing machine, we will not repeat ourselves. So, having reached the heating element, we do the following.

We disconnect the wire from the temperature sensor, and then pull the part out of the niche.
We measure the resistance of the sensor using a special device called a multimeter. If the device shows zero or one, feel free to throw out the temperature sensor and put a new one in its place.
Then we assemble and check the repaired washing machine.

If the temperature sensor turns out to be intact, there will be no problems with the wires and contacts supplying it, then the problem is in the control module. You shouldn’t repair the control module of a Samsung washing machine yourself, since this is a rather complicated matter; the slightest mistake can aggravate the problem and result in significant expenses. Entrust the repair of the electronic part of the washing machine to a professional.

To summarize, we note that the HE1 error in a Samsung washing machine is quite easy to decipher, but fixing the breakdowns that gave rise to this error can be oh so difficult. But we are optimists by nature and believe that everything will work out for you, the main thing is to read our instructions carefully. Good luck!
