Entering Service Mode and Calibration Necessity for Electrolux ESF4510ROX After i40 Error

Hello,

I have a dishwasher as in the subject. Please let me know how to enter the service mode and whether calibration of the dishwasher is required?
The fault was the i40 error, strange things happen after replacing the hydrostat.

Model: ESF4510ROX
PNC: 911656007/04

thanks and best regards

In case of such an error, the hydrostat will need to be replaced, unless you somehow manage to clean it and not damage the service unit, you can find it here https://www.elektroda.pl/rtvforum/topic3092281.html#15016595

I just put a new one in the hydrostat. And the instructions in the link are not for this model.

If the service manual for the Electrolux segment does not suit your dishwasher, then GH EDW1600 page 28 ...

I have such a panel and a completely different button layout. Ok, I managed to enter service mode...

Hold down the two left buttons and turn on the power. In service mode it shows errors: i41 and i44 .
After running the test program for 15 minutes, it performs all functions correctly. After exiting the service mode, the washing program still does not work. It pours and pours out water at the same time and so on.

Have you reset (deleted) the errors?

If only I knew how all key combinations by trial and error.

You hold down the two left buttons and turn on the power, when the LEDs start to glow, release the two left ones and click the lower left one once (all the LEDs and the two eights should be lit + a sound signal) and that`s it...

That`s how I figured it out. The errors were cleared, but nothing changed. Downloading and pouring at the same time...

Which of these hydrostats does your dishwasher have?

I have this one:

Aha is a dishwasher built at the Solaro factory. The error shows that the hydrostat is apparently not working, or maybe your channels are clogged, have you cleaned everything?

I bought a new hydrostat. It is unlikely that it is also damaged, although it is possible It`s strange that on the test 15` it works so well.

Everything clean...

You also have descriptions of LED errors here https://www.elektroda.pl/rtvforum/topic3120578.html#15179284

Maybe you have a clogged strainer on the water supply hose, which is why error i41 "water intake time" appears.

Enter the test and check for errors. If 41 and 44 again - check the power supply of the level sensor, see the signals on the control board with an oscilloscope.

The test program completes without any errors. Washing still doesn`t work...

I had a similar phenomenon
Neither deleting nor calibrating helped if I did these two procedures separately.
Only after I first cleared the error and disconnected the power supply, and only then calibrated it as part of the test program and disconnected the power supply.
After this combination, the dishwasher started

Unfortunately, this doesn`t help either.

Maybe it`s time to use an oscilloscope to see if the hydrostat is drawing water?

Hello, I would like to ask if the problem has been solved, because I have an identical one, the hydrostat has been replaced and the error has been cleared. Additionally, after replacing the hydrostat, the dishwasher "kicked" me, I corrected the hydrostat plug with the power on and touched the housing. I don`t know why when I turn on the dishwasher there is 220V voltage. The dishwasher itself has no puncture. Thank you in advance for your answer.

Check if the hydrostat chamber is not clogged. I had such a situation several times, related to impurities accumulated in the chamber.

Thank you very much, I haven`t taken it apart yet, I`ll definitely check it out.

Thank you again, the small partition to which the hydrostat is attached turned out to be clogged.

This is the hydrostat chamber - air is compressed there through the water surface and pushed into the hydrostat. You didn`t have to dismantle the entire bowl, you just had to apply water under pressure.

Speaking of digging - check the electrical installation. Metal casings of dishwashers, washing machines, refrigerators, computers, etc. must be connected to earth via the grounding pin in the socket. If the socket to which the dishwasher is connected is without a pin, it should be replaced with a suitable one. If the pin is there but not connected to ground, or is connected incorrectly (e.g. to the phase!!!), then we have voltage on the housing... This is a very serious matter. Check this and, preferably, call a qualified electrician.

Hello.
Can someone tell me how to run the test program in the Electrolux ESF 4510 dishwasher?

Can your friend read? For example, in this topic, posts no. #5 and #8 and many more...

Where exactly should we apply this pressurized water and what is the best way to do it?

I also managed to solve the problem (Electrolux ESL67070R)

Despite replacing the hydrostat earlier, the dishwasher still interrupted the washing program from time to time, throwing errors, including i20. Calibration didn`t help. Reluctantly, I started repairing it again, which in a home environment can be nerve-wracking... After getting under the housing, this time (after reading the electrode) I started by disconnecting the gray hydrostat hose from the bowl. Then I did something I had skipped before - I looked inside the spigot - EUREKA! The bowl is more or less beige in color, so the interior should look similar, but this time it was black... Old, dirty grease accumulated on the walls, which resulted in the fact that when the water temperature increased (then the error most often occurred), the entire the crap dissolved a bit and clogged the holes through which the liquid should move freely when it changes its level, thus causing a change in the pressure of the air column. However, this flow was disturbed and the hydrostat sent incorrect information to the controller. The pump tried to pump out water that had been gone for a long time, and finally the controller threw an error.

To clean it, I simply used a popular kitchen cleaning product called "grease and streaks", because that`s what I had at hand, and hot water. I used a syringe to inject both into the nozzle several times, until all the crap started falling off and coming out in flakes, until the inside was clean. After assembling, I ran the calibration program and that`s it. Since then, the dishwasher has been working beautifully
I came to one more conclusion - I suspect that I replaced the hydrostat excessively, but hey, one learns from mistakes.

I understand that it is about the connector in the photo.
