It can be very annoying when your Daewoo washing machine shows an E8 error. This code typically appears when there’s a problem with the washing machine’s ability to drain water properly or with the water level sensor.
You can save time and money by knowing what causes the E8 error and how to fix it. Oftentimes, you don’t need a technician to solve the issue on your own.
This guide will examine the typical causes of the E8 error in Daewoo washing machines and offer easy-to-follow instructions to get your
What does this code mean?
Error E8 is present in Daewoo vertical loading models as well as front-loading washing machines. It makes no difference when the machine was manufactured—both new and old models are vulnerable. Regarding the cause of the issue, the manufacturer offers the following code decryption:
- breakdown of the tachogenerator responsible for regulating engine speed (also called the Hall sensor);
- malfunction of the control module (more precisely, burnout of one of the board elements, most often, the motor control triac);
- engine failure.
It is not advised to perform independent control board diagnostics and repairs as this will call for a high level of caution, specialized knowledge, and tools.
Inspecting the machine while it’s in use will help you identify the issue’s root cause more precisely. Therefore, start by checking the engine of the washing machine if the drum fails to accelerate to the desired speed, spins slowly, or even stops in the middle of the cycle. Conversely, if the machine accelerates excessively or oscillates between minimum and maximum values frequently, you should take notice of the Hall sensor. However, a defective board usually manifests itself, so it is preferable to diagnose the control module first.
When a Daewoo washing machine displays error E8, it typically means that there is an issue with the drainage or water supply system. A kinked hose, a clogged filter, or a problem with the water inlet valve can all be the cause of this error. Make sure the filters are clean, that no debris is obstructing the drainage, and inspect the hoses for obstructions in order to resolve the E8 error. Knowing the typical causes of this error will enable you to locate and fix the problem fast, keeping your washing machine in good operating order.
Testing the elements of the control board
You have made the decision to fix the control board on your own. After that, it will be up to you to determine which component of the module that controls the engine’s operation has malfunctioned. A schematic of the electronic unit will make your task easier and prevent you from speculating or experimenting. Usually, it can be found in the washing machine’s factory instructions.
Visible to the unaided eye are mechanical damage to the board, burnout of the contacts, and electrode disconnection.
The top portion of the machine is then disassembled, and the board is carefully removed. Examine the module from both sides, looking for any obvious scratches, chips, loose connections, burned tracks, or broken electrodes before beginning any multimeter testing. If such damage is present, the only thing left to do is solve the identified issue; a thorough diagnosis is not required. Once everything appears to be in order, it is worthwhile to examine each board element individually.
- Capacitor. A burnt-out capacitor often leads to error E8. On washing machine units, it acts as a stabilizer and takes the brunt of voltage surges. It is impossible to repair a burnt-out element, you will have to dismantle the "box", select a similar one and solder it with a lamp to the vacated space. If you additionally install filters, you can reduce the risk of re-ignition. But keep in mind that the condensate is connected to the board only to the positive electrode, and a multimeter is used to check the resistance of the circuit.
- Resistors. The most common cause of board burnout is sensitive resistors. To fix the situation, it is necessary to test the module by measuring the resistance with a multimeter. First, the probes are connected to the first line, where the value should approach 8 Ohms, and the overload indicator is less than 2A. Next, the second line is evaluated, where the overload is limited to 3-5A. The final resistance depends on the frequency of the unit, for example, for a simple circuit, the parameter will not exceed 10 Ohms. If deviations from the norm are recorded, then the elements need to be re-soldered. Professionals also recommend replacing the filters.
- Thyristor unit. It fails if the network was overloaded above 220 W or there was impulsive interference. In this case, it will be difficult to repair it yourself, but it is quite possible. First, measure the negative resistance of the board, which on first-order diodes should not exceed 20V. Output contacts rarely burn out, but they also need to be checked. Take a tester, clean the cathode and evaluate the indicators. When the average value fluctuates within 12V, the test is passed, and in other cases, change the faulty filter. Buy a new element and solder it through the positive contact to the thyristor block. The main thing is to monitor the condition of the flimsy but expensive ports, and thoroughly clean the module upon completion of the work.
- Trigger. Breaks due to failures from the capacitor. Diagnostics are carried out using a multimeter, which is connected to the output contacts and a filter installed nearby. If the first indicator on the tester is approximately 12V, and the second is about 20V, then everything is fine. Otherwise, it will have to be repaired, which will take a lot of time. First, the outlet valves are soldered, then a new trigger is mounted, the threshold voltage and resistance on the modulator are measured. The main thing is to be careful with the capacitor cathode (it is easy to touch and damage when soldering the "neighbor").
These are the primary "sore spots" on the control board where the error code E8 may appear. If you have experience and practical knowledge, you can check and repair them yourself. Focus on the engine and tachogenerator if the module diagnostics were unable to identify the issue.

While getting an E8 error in your Daewoo washing machine can be annoying, you can usually fix it on your own. You can easily get your washing machine operating again by knowing what this error code means and taking the appropriate action.
The E8 error typically denotes a problem with the water supply or the water level sensor. To begin with, make sure the hoses are connected correctly and the water supply is steady. A common solution is to make sure the hoses and filters are free of kinks and obstructions. If theproblem continues, it might be required to look over the
