Samsung Washing Machine Error HE1

The HE1 error in a Samsung washing machine is quite common and can appear at any stage of its operation. There are a few possible causes, but all of them pose a serious threat. If the control module stops the washing machine and displays this error, it's effectively saving your property from serious damage. This article explains how this error is interpreted, what malfunctions can cause it, and how to troubleshoot it.

Let's decipher it first

When it comes to the self-diagnostic system of Samsung washing machines, it's safe to say that any code beginning with the English letter "H" indicates a problem with the heating element, while subsequent letters and numbers specify the type of problem. In our case, HE1 literally means that the water in the tank is heated by more than 40⁰In 2 minutes. What's going on? The heating element is heating up too quickly, and it's doing so regardless of the washing program's algorithms.

If the self-diagnostic system does not stop heating the water in this situation, the heating element will soon bring it to a boil and burn out, simultaneously damaging delicate items you may have placed in the washing drum with boiling water.

The HE1 error prompts the technician to believe that the heating element is working properly, there's no open circuit, but something is causing it to malfunction. This is the advantage of three-digit codes in Samsung washing machines' self-diagnostic systems: they convey fault information more accurately than two-digit codes, saving the technician time troubleshooting.

You don't have to look far for an example. Samsung washing machines with a two-digit self-diagnosis code have error H2, which indicates a heating system failure. It's hard to guess what the problem is, or what its nature is. You won't understand until you open the washing machine. The three-digit code allows you to perform a targeted troubleshooting—speaking of failures, by the way.

Possible reasons for the appearance

If you see the HE1 error code on your washing machine's display, prepare to troubleshoot the problem, as it's definitely not a power surge or a short-term electronic failure. What faults can cause the HE1 error? There are two such faults: a faulty temperature sensor and a broken control board.

The temperature sensor sends information about the heating element's temperature. Using this sensor, the control module can regulate the heating element's temperature according to the washing program. If the temperature sensor fails, the control module loses control of the heating element, and by default, it begins heating up to maximum temperature after the Samsung washing machine is turned on. If the control module receives no information from the temperature sensor for several minutes, it automatically shuts down the heating element and generates an HE1 error, stopping the washing machine.

The temperature sensor in a Samsung washing machine is usually located directly on the heating element, so finding it shouldn't be difficult. You'll still need to get to the heating element itself, but that's manageable.

Temperature sensor failures in Samsung washing machines are quite common, but sometimes the sensor itself isn't the cause. What then is the cause of the error? In this case, the fault lies in the control module itself. If the track or the triac controlling the heating element burns out, this also causes the HE1 error, but repairs are significantly more complex and expensive.

We eliminate the causes

A temperature sensor is usually impossible to repair—it must be replaced. However, to confirm the component's fault, it should be tested with a multimeter before replacement. To check and replace the temperature sensor, you'll need to remove the front panel of your Samsung washing machine. This article explains in detail how to disassemble the front panel of this brand's washing machine. How to repair a Samsung washing machineWe won't repeat ourselves. So, once we reach the heating element, we do the following.

• We disconnect the wire from the temperature sensor and then remove the part from the niche.
• We measure the resistance of the sensor using a special device called a multimeter. If the device shows zero or one, safely throw away the temperature sensor and put a new one in its place.
• After which we assemble and test the repaired washing machine.

If the temperature sensor is intact, and there are no problems with the power wires and contacts, then the problem lies with the control module. Repairing a Samsung washing machine's control module yourself is not recommended, as it's quite complex, and the slightest mistake can worsen the problem and result in significant expenses. Entrust repair of the washing machine's electronics to a professional.

To summarize, the HE1 error in a Samsung washing machine is quite simple to decipher, but fixing the problems that caused it can be quite challenging. But we're optimists by nature and believe you'll succeed, just read our instructions carefully. Good luck!
