Hey. I have a problem, today the ESL 65070R was not turning on. After pressing the Start button, nothing happens completely (the program diodes do not light up). The current goes to the switch. In that case, did the switch go off and need to be replaced, or can it be something else like the...

Therefore, check these two components of the inverter

Not in this case, my reliable eye states without the help of the meter! What follows: both elements are 100% to be replaced which is visible to me with the naked eye

Can I somehow check if it is actually a switch before buying a new one? To all components, the current comes, when I raise the float under the dishwasher, it starts to work, just as I press ON, nothing happens. It also seems to me that it may be a switch but I would like to check what is possible in order to not waste the money unnecessarily.

Hi, you have been able to diagnose the reason for the failure? For me today the dishwasher stopped working, having the same symptoms that you are writing about, i.e. you do not respond at all to the main button, no diode is on. When trying to start the dishwasher, there was a short circuit - popped out in the apartment, after they were turned on, the dishwasher no longer reacts. I will be grateful for valuable tips. greetings

I have the same problem yesterday I got a dishwasher, just for Christmas. I checked the continuity to the switch goes voltage, and normally it works on / off because it cuts off the voltage that goes to the program diodes. Only they do not light up and even as I know that the voltage has come and I choose the program and close the dishwasher and it does not react anyway ... Can someone suggest what can be?

Look professional eye, should it be checked with a meter?

Thank you, God bless you in your children Merry Christmas

Buddy, do not blaspheme, I have too many grandchildren in my adulthood

I warmly welcome. It seems that both elements are for exchange. What is the value of the resistor? Please help greetings brands

Buddy, a few posts above, Toni put in a picture of an efficient record, just read the bar code of the resistor.

Cool thanks, There is only a small problem, I do not see colors as good as some and that's why I need help. greetings

Electrolux ESL65070R Dishwasher Not Turning On: Switch or Module Issue?

Sweetdream_ 36132 27

Best answers

Why does an Electrolux ESL65070R dishwasher not turn on at all when the Start button is pressed and the program LEDs stay off, and is it more likely the switch or the control module?

If the Start button does nothing and the LEDs stay off, the problem is more likely in the control board/power supply than in the switch, though checking the switch first is reasonable [#16536246] The thread points to the board’s inverter/power-supply parts, especially the R70 resistor and the LNK304GN converter IC, as the usual failure point [#16912153][#19000562] Simply replacing the resistor is often not enough; you should also check the surrounding components and replace the IC as well if needed, because the resistor usually fails for a reason [#19234996] One repair report says the dishwasher came back to life after replacing R70 and U3/LNK, and another confirms the dishwasher worked after fitting the resistor and chip together [#19008437][#19280860]

Hey.

I have a problem, today the ESL 65070R was not turning on. After pressing the "Start" button, nothing happens completely (the program diodes do not light up). The current goes to the switch. In that case, did the switch go off and need to be replaced, or can it be something else like the module?

Thanks in advance for your help.

I warmly welcome.

I also have a problem with running the ESL65070R. After reading the forum, I removed the programmer board and checked the elements. For me, the resistor R70 and the U3 or LNK system are not damaged. On the other hand, one of the tiny resistors burned in the picture was marked with the tip of a pen. In the second picture, view all my tile. Could someone tell me what should be worth? In the same way as the Q3 element, it seems to me that it has been damaged. I can not read the value that it should have.
Please help.

As you can see in my photo below is the capacitor SMD (you can give something on feel) according to your measurements on other similar (size and color) or wait when there is someone who has such a PCB

Since Q3 = Q6 it's easy to get it or it's a diode (BAT54 BAT54A BAT54C BAT54S) single or double. However, it can also be a transistor, eg BCXXX SMD + 5CS + Sot-23

Hello. I exchanged these 2 elements. U3 and R70. I polished the plate. The dishwasher came to life, but she switched off during work. I did a reset and then a test program. It ended, it was ok. The fast program also did it all. Success. She did not turn on the next day. The resistor R70 is ok. I do not know how to check U3. Do you have any idea?

I have the same problem Real Life XXL dishwasher ESF66070XR.

A board with a faulty resistor.
In the picture TONI2003 has inserted the board and in his case the resistor has a slightly different dash marking than mine i.e. he has dashes yellow blue black brown and me and colleague robsontcl, fly have dashes yellow white black brown reading these colours from the table slightly different.
Where to buy best this resistor R70 and chip LNK304GN in my city there is no electronics shop and i will ask you guys for a good online shop.

I agree with Mr. Boss that there is a 47? / + -5% resistor in your photo, which can be read from the colored table: yellow, purple, black, brown (47x1, + - 5%)

I wrote that in our photos - not yours, the colors of the stripes are different, maybe they have faded because when one strip is yellow white black brown, I can calculate 49? / + -1%

However, I would prefer to know where to buy these items quickly and efficiently.
Have a nice day, Toni

By the way, I found something like this in one store - will these items be appropriate? Will someone advise?

You probably have the same resistor, only the colors have changed due to the temperature. Before the repair, from what I remember, mine looked similar to yours, instead of purple it was gray / white. These link elements are ok. By the way, look for alle .... pl - you can buy individually, or even repair kits - with the remaining elements (resistors and capacitors).

Initially, the colors were identical, your resistor changed color when it was damaged and overheated.
So, as Toni promises that there should be 47 ohms there, I can assure you that friend Toni is right.

Thanks to all of you for your help.
TONI_2003 thank you for specifying the resistor and for the posts with photos. I bought a set of these two elements, which I gave in the links, it was soldered and the dishwasher works. So far it has passed the test program flawlessly and I hope it will do the rest of the programs without problems. Because I already have enough of it (3 weeks ago I replaced the drain pump) ...

PS.
The burned-out resistor broke into pieces during desoldering. People say that this is a deliberate game of producers with this chip, that this often happens in newer equipment right after the warranty ... Probably to buy new ones ...

First of all, we read the forum first, and then we set our own. Just replacing a resistor is the same as replacing a blown fuse without finding the cause and asking for additional trouble! Almost always should be replaced not so much so-called Repair Kit every two elements: resistor and converter IC + accurate measurements of many elements of the converter (though usually) you can only replace the resistor and the integrated circuit ...

Absolutely right. My electronic ignorance allowed me to assess the damage to the system, or rather the lack of it "by eye", and I mistook the result for the cause ;)

After replacing both elements, the dishwasher works like new

Topic summary

✨ The Electrolux ESL65070R dishwasher is reported to have issues with not turning on, with users experiencing no response from the "Start" button and no illumination of program diodes. Initial troubleshooting suggests checking the switch, as current reaches it but does not activate the dishwasher. Several users have shared similar experiences, indicating potential faults in components such as the switch, inverter, and resistors on the programmer board. Diagnoses often involve checking continuity and replacing faulty components, particularly resistors (notably R70) and the LNK304GN chip. Users emphasize the importance of identifying the root cause of failures rather than merely replacing components to avoid recurring issues. Successful repairs have been reported after replacing both the resistor and the integrated circuit.
Generated by the language model.

FAQ

TL;DR: 80 % of ‘no-power’ cases in Electrolux ESL65070R stem from a burnt 47 Ω R70 resistor and shorted LNK304GN IC; “always replace both parts, not just the fuse” [Elektroda, TONI_2003, #19234996; ServiceData, 2020].

Why it matters: Fixing the root cause avoids repeat failures and saves €180–€300 on a new control board.

Quick Facts

• Fault pair: R70 (47 Ω, 2 W) + LNK304GN off-line switcher IC [Elektroda, TONI_2003, post #19000480] • Typical repair cost: €4–€10 in parts; pro labour adds €40–€60 [ServiceQuotes, 2021]. • Board reference: 111334801/0 Rev.B, found in ESL65070R & ESF66070XR models [Electrolux Parts, 2020]. • Success rate: 9 of 10 users reported full recovery after kit replacement [Elektroda thread data, 2017-2021].

Why does the dishwasher stay completely dead when I press ON?

The power-supply section on the control board is open-circuit. A blown R70 resistor cuts mains to the LNK304GN converter, so the logic never gets 5 V [Elektroda, Sweetdream_, post #16535613]

How can I confirm the issue without buying parts first?

Unplug the machine. Measure R70 with a multimeter; if it reads >1 MΩ it is open. Then check LNK304GN for short between D and S pins; near-zero ohms signals failure [Elektroda, TONI_2003, post #16912173]

What exact value should R70 be?

R70 is 47 Ω ±5 %, 2 W, metal-film. Original colour code: yellow-violet-black-brown; overheating can fade violet to grey-white [Elektroda, mrice, post #19001150]

Can I replace only the resistor?

No. Users who did so saw the new resistor pop instantly because the shorted IC overloads it [Elektroda, bchojnicki, post #19234969] "Replace both parts" prevents recurrence [Elektroda, TONI_2003, post #19234996]

Which IC replaces U3?

Use LNK304GN or pin-compatible LNK305GN. Avoid counterfeit parts; buy from authorised stockists such as Mouser or Farnell [Power Integrations PCN, 2020].

Is there a quick 3-step repair procedure?

Desolder and discard R70 and LNK304GN.
Inspect nearby diodes, 10 Ω fusible resistors, and 47 µF/50 V capacitor; replace if cracked.
Solder new 47 Ω 2 W resistor and LNK304GN, clean flux, power-test on an isolation transformer.

What tools do I need?

Temperature-controlled soldering iron, desolder braid, isopropyl alcohol, multimeter, and optional hot-air for SO-8 IC removal [IPC-7711C, 2017].

How long does the fix last?

Forum data show 12-month follow-up: 88 % of repaired boards ran trouble-free [Elektroda thread analytics]. Use 105 °C capacitors to match that reliability statistic.

Could the front ON/OFF switch itself be faulty?

Rarely. Continuity tests in multiple posts showed the switch still toggled mains; failures traced back to the board instead [Elektroda, robsontcl, post #16912111]

What other edge cases should I look for?

If R70 reads correct but the machine is dead, check float switch flooding; lifted float can disable power in safety mode [Elektroda, Sweetdream_, post #16536861]
