Gorenje dishwasher errors
The Gorenje dishwasher control module can notify the user or technician that the equipment has one or another malfunction. How he does it? Of course, using Gorenje dishwasher error codes. There are very few of these errors in the database, so we have a rare opportunity to describe them in more or less detail in one publication. Let's try to do this.
What do these or those codes mean?
To begin with, it is necessary to say that Gorenje dishwashers are still available in two versions: with and without a display. All machines have a self-diagnosis system, but it interacts with the user differently. So, let's start listing the fault codes.
- E1 On a machine without a screen, this code is represented by two glowing indicators: the first and the last. This means the activation of a special sensor located in the pan of the machine and protecting its body from leaks.
- E2, E9. The second and last indicator lights up, counting from left to right. This makes itself felt by the pressure switch, which has detected an excessive amount of water being poured into the machine.
- E3 The following indicators are lit: first, second and last, counting from left to right. This error records the fact that the system cannot bring the water to the set temperature.
The water heating temperature is set by a program embedded in the control module and can be adjusted by the user. The module monitors the actual heating temperature and compares it with the value specified by the program.
- E4 The third and last indicator lights up, counting from left to right. This code appears when communication with the temperature sensor is lost.
- E5 The first, third and last indicator lights up, counting from left to right. What does this code indicate? And he indicates that the flow of water into the machine is too slow, or the water does not flow there at all.
- E6 Indicators are lit: second, third and last. This indicates problems with removing waste water from the dishwasher system.
What to do if a leak occurs?
When code E1 appears, the user must immediately turn off the power to the dishwasher, turn off the water supply to it and check the tray. Perhaps there really is a lot of water in the sump, or maybe the leakage sensor just worked idly. Both can happen with equal probability. True, you can look under the body of the Gorenye dishwasher. If it is wet there, it means there is still a leak. What to do in this case?
- First of all, restart the machine and see if the error appears again.
- If the error appears again, you need to turn off the machine, pull it out and remove the side cover of the case.
- Reach your hand into the pan and feel the bottom. If there is no water there, then press the sensor float with your finger and check whether the machine will work after that.
- If there is a lot of water in the pan, you need to drain it. Take some strong stand and a basin. Lift the machine and place it on the stand, place a basin next to it. Tilt the machine body towards the basin and drain the water.
- Look where the water was coming from and fix the leak. Most likely, you will have to change the pipe or body of the circulation unit, but it is possible that the rubber gasket has simply become leaky or the clamp has become loose.
- Reassemble the machine and check if the error appears again.
If there is no water in the pan and the sensor does not want to work, it can be replaced.But first, you need to “ring” the wiring that communicates with this sensor with a multimeter and, probably, test the control module. If the tire responsible for interacting with the leakage sensor has burned out, you will have to contact a technician so that he can professionally eliminate this unpleasant defect.
Overflow of water
Having witnessed the appearance of code E2, E9, the user should not turn off the power to the machine and turn off the water supply. Instead, you need to reboot the machine and see how it behaves. It is necessary to repeat the reboot several times in order to completely eliminate a short-term system failure.
Next, you need to turn off the Gorenje dishwasher, unhook the right or left wall of the case, and then check the tray. If the pan is dry, disconnect the blue wire from the pressure switch. Next, we connect the machine and turn on the very first program. If the machine begins to drain water, it means that the control module can be excluded from the list of possible problems. If the machine starts pumping water, it means the control board is broken.
The second situation does not necessarily require replacing the control board. You need to call a technician who will reset the firmware or reflash the board. In more than half of the cases, this is enough to restore control.
If we have excluded the control module, we need to remove the thin rubber hose from the pressure switch tube and carefully inspect it. Pressure must be maintained inside the hose, and if there is even the slightest damage to it, it must be replaced. Also inspect the level sensor tube. Small debris may accumulate in it, which needs to be cleaned out. Check the resistance of the pressure switch, and also check its wiring.
If everything is in order, then the last thing you need to inspect is the inlet hose. In slightly more rare cases, the pressure switch begins to work incorrectly or refuses to work due to a blockage in the inlet hose. Due to the blockage, water begins to flow unevenly. Air bubbles form inside, which ultimately enter the hose and tube of the part, interfering with its operation. By removing the blockage, you will restore normal operation of the system.
The water doesn't heat up
Code E3 lights up on the display; you should pay attention to how cold the machine washes dishes with water. In winter, this is especially noticeable, since simply icy water accumulates at the bottom of the washing chamber. If the water inside is hot, this indirectly indicates a breakdown of the control module, which incorrectly reads the readings from the temperature sensor. Well, let’s not talk about sad things ahead of time. To begin, let's do the following:
- unscrew the front protective panel, which is located under the dishwasher door, and also unscrew the left side wall;
- Having gained access to the heating element and the temperature sensor, we won’t go to them in the first few steps; first we will find the thermal fuse, which is found on many models of Gorenye dishwashers;
- Having found this part, take a multimeter and check whether this fuse has worked or not. Readings close to zero indicate that the fuse has not tripped;
- If the fuse is intact, check the resistance of the heating element. If the multimeter shows 25-30 Ohms, then the heating element is in order; if the value approaches zero, the part must be changed.
- Let's check the thermistor and its wiring; most likely, the breakdown is hidden there.
In such a situation, failure of the control module also cannot be ruled out.If, after doing all of the above, you do not find any defects, you can invite a specialist to test the electronics. You shouldn't do this on your own.
Thermal sensor does not function
Error code E4 specifically indicates that the temperature sensor requires repair. However, there are nuances here too. The temperature sensor may actually be broken, or perhaps the wiring leading to it may be broken. The contacts may also burn slightly, or the control module may fail, which will no longer recognize this part.
We will try not to think about possible problems with electronics for now; we will check the temperature sensor and wiring one by one with a multimeter. Depending on the identified problem, we replace the sensor or the broken wiring.
No or not enough water
Error E5 appears if the machine does not draw water at the proper speed or does not draw it at all. First of all, you need to see if the inlet hose is pinched. It may be that the water utility has turned off the water supply, so water is not flowing into the machine. Having eliminated elementary errors, we move on to identifying more complex defects.
At the same time, it is worth checking the inlet valve for blockages. Quite often the valve mesh becomes clogged and due to this defect the valve cannot operate normally.
Through the side wall we get to the intake valve and check its resistance with an ohmmeter. If the valve is functioning normally, you should also check its supply wiring. Failures in the electronics of the dishwasher cannot be ruled out.
Waste water does not drain away
When you start the waste water discharge program, the control module detects the time during which the machine will remove all dirty water from the system. If the water is discharged more slowly than 3 minutes, the control module will display error E6. We need to look for the reason.
- First of all, you need to make sure that the garbage filter is completely clean.
- Next you need to check the drain hose and siphon for blockages and squeezing.
- We turn off the machine, remove the side cover of the housing and check in turn the pressure switch, drain pump and wiring leading to these parts. To check we need a multimeter.
- If you can identify a fault in one of the parts, you should not try to repair it. Only replacement will help here.
So, we looked at what the various Gorenje dishwasher error codes mean and, most importantly, we looked at how to fix these errors. Try to look for defects yourself, but be reasonable. If you cannot identify the problem yourself, feel free to contact a specialist. A qualified specialist will definitely help you.
