In this short tutorial I'll explain how to fix a very common problem with about 3 to 6 years old AEG or Electrolux dishwashers. If the dishwasher works otherwise, but doesn't heat up the water anymore, the problem is very likely to be broken soldering in the circuit board. The problem can easily be fixed by just resoldering the broken connection.

In this tutorial I fixed an AEG Electrolux model 40660 dishwasher, but lots of people have reported that this fix works for many other models too.

Step 1: Opening the Front Panel

Start by unplugging the mains power connector for safety reasons.

Next, open the washers front door and unscrew the six screws pointed out by the red arrows in the picture. This allows for the top panel on the outside to come off, so you can remove the control box.

Step 2: Removing the Top Panel

Carefully pull out the top panel a bit by pulling towards yourself. Watch for the power switch cables (pointed out with the blue circle in the picture) and the door opener lever (green arrow in the picture).

Unplug the power switch (blue circle) carefully so you don't break the wiring.

The door opener lever comes out of it's position by moving the top panel to the side a bit. Watch the lever (green arrow) as it gets free from the opener.

Step 3: Removing the Circuit Board Box

Note the two small plastic clips that secures the circuit board box in the top panel. Carefully push the clips so that the control box detaches from the top panel.

After unclipping the control box, carefully pull it out a bit to get access to the cable connectors at the back. Take note of the order and placing of the different connectors before unplugging them so that you don't forget in which order they should be inserted back after the repair. A quick way of doing this is taking a picture of the connectors with your cell phone camera.

Step 4: Opening the Control Box

The control box containing the circuit board can be opened by opening the two plastic clips on each side of the box. The control box opens up like a book when pulling the halfs apart at the connector side.

The relay to be soldered is pointed out with a red arrow in the lower picture.

Step 5: Soldering the Relay

The problem is often very well visible when you open up the control box. In many cases there is a burned area that tells you where the soldering is broken. In some cases there are no visible marks of burning, but many report that the problem is still the same, so give it a try anyway, even if there is no visible burning.

In this case the copper track was burned so bad, that I had to solder a small piece of wire (by the red arrow in the picture) to make contact between the relay's leg and the copper track. It is a good idea to solder all of the relay's legs while you're at it anyway. Resolder the legs pointed out by the yellow arrows too, so you don't have to open the dishwasher up again soon.

If you look at the circuit board you'll find the relay itself on the other side (where all the components are). It looks like a small black box, and by comparing it to the position of the legs on the back side of the circuit board (showing in the picture), you can find the right legs to resolder quite easily.

After soldering, just assemble everything back in the opposite order to make you dishwasher work again!
<p>Many thanks. Just fixed my 85480 fully integrated. More complicated to dis-assemble but exact same fault. Hot tip: put some flux on the relay pin and pad before you solder. Makes it much easier and quicker to get a good joint.</p>
<p>I had a same problem with electrolux esl 6124. No heating. I was so angry when I paid 30&euro; for 2 minuts of diagnostics of this problem. I had to pay half of a new dish wash to solve this problem.</p><p>I did the soldering and it hetas again.</p><p>Thanks a lot. </p>
<p>Thank you very much!<br>You saved me a lot of money.</p>
<p>Thank you very much! My AEG Favorit 50740 Sensorlogic Turbodry didn't heat anymore. I did what you said and encountered exactly the same problem as you described and as the photo showed. I soldered it and it heats again! This saves me a new dishwasher and helps the environment! Thank you for your effort to post your experiences here!</p>
<p>Many thanks! I followed the description, did the soldering and now the dishwasher works again! You saved me a lot of money and hassle, thanks again.</p>
<p>Aeg favorit 40630 stopped working. When the washing program is started, the first step works - water is drained out but is stucked at second one - water to get in. I checked if water is drained out correctly by throwing some water inside washing machine and checked the draining hose - water is getting out. After doing nothing at second step - water getting in error light blinks. PLease help - unhappy wife :-)</p>
<p>Yes this also worked for me for an AEG dishwasher purchased through Wickes about 2012, the control board was slightly different , but I just re-flowed the relay joints and saved myself &pound;400, plus all the hassle of changing etc - brill!!!!</p><p>If this doesn't work the next thing would be to remove and test the relay, its a standard 12VDC single pole double throw relay from Panasonic, if you put the part number in google it will give you several vendors, will only cost a couple of quid. </p>
<p>Thanks.This worked perfectly. KUTGW</p>
<p>Hi, I have an AEG Favorite F87000MP, and it has no power. The timer board gets 230 V, but it still doesn't work. Anyone has any idea on what the problem may be?</p>
<p>I fixed my 2006 Electrolux ESL6251 by this procedure. Thanks!</p>
<p>A little bit more work to do, due to more electronics and buttons on the top of the front door and bigger cicuit board (at opposite side), but ended well :-)</p>
<p>I created an account here only to say Thank You! This worked like a charm. Even though my dishwasher model was different, the parts were exactly where you said they would be, the problem was exactly where you said it would be. Great instructions! You saved me an expensive repair or probably a new dishwasher!</p>
<p>i have an electrolux diswasher </p><p>which turns on but does not start any cycle.</p><p>can anyone help me!</p>
<p>It worked for me too!</p><p>Thanks</p><p>AEG Favorit sensorlogic</p>
<p>Worked for me!!! Thanks a lot!</p><p>AEG Favorit 40840<br></p>
Didn't work for mine. I guess it must be the element.
<p>I have an AEG FAVORIT 55011 I model.<br>It doesn-t work properly.<br>The water is not hot, only lukewarm</p><p>I examined the control panel, but I do not see any mistake with my eyes.</p><p>What could be the problem?<br>Where can I find service manual?<br>( Sorry for my English. :-) )</p>
<p>I found this page while searching the internet for the part number of my circuit board of a German &quot;privileg&quot; dishwasher... I was wondering if somebody would be selling an used circuit board, because our dish washer sometimes worked with cold, sometimes with hot water. Now I tried soldering, and it worked fine! Thanks!</p><p>Does anybody here have an idea why this problem is occurring this frequently?</p>
<p>Bingo!! The circuit board did not show any signs of overheating, and the four relay connection points seemed ok on a close visual inspection, but I resoldered them anyhow and the dishwasher is back to normal (at least on my first test). Will report any future problems on here but, fingers crossed, you have solved the problem - very many thanks. Not sure what I'm going to do with my spare element?</p>
<p>I will be trying this tomorrow and will let you know I get on. Have already bought and fitted a new heating element which didn't solve the problem (so now have a spare element)!</p>
Never soldered before, but 13 euro on basic solder iron set, 20 minutes work, 15 minutes of suspense running first cycle after reassembly, but its heating!!! Thank you so much
This really worked a treat saved some hard earned money
Kiitos hyvin toimii ohjeen avulla
<p>I have this brand of Dishwasher that has just stopped working. I've watched some videos explaining that it could be the fuse. However this model is 'completely' different to the models being shown. Can anyone advise where I would locate the fuse on this model? I have DX303.</p><p>Thanks,<br>Jeff</p>
<p>Worked. Thanks!</p><p>One of the connector cables in my device seemed to be glued to the circuit board so I did the soldering while the board was still attached to the machine. </p>
<p>Thank you. I took the board apart and it looked perfect but I soldered the circuit board as shown and it fixed the problem. Saved me 400 for a new dishwasher. Brilliant !!!!!!</p>
<p>AEG dishwasher now has hot wash! - Great advice - worked as you said even though there was no obvious burn / solder failure. Hint: When taking the contact plugs off the main control box, note that there are tiny plastic tabs at the bottom of each socket that need to be 'gently' eased downwards to allow the plugs to come out easily - also make sure that the contacts on the control board are clean &amp; shiny. Local repair &quot;experts&quot; indicated dishwasher not worth repairing, as would be half cost of new machine. Will be sending small donation to sight-saving charity as thanks to you.Thanks again</p>

<p>AEG Electrolux - FAV55080VI<br>It worked! Thank you so much!</p>
<p>You are amazing, this worked a treat! Thanks for the excellent instructions and photos, this saved us a fortune:)</p>
<p>Hi I have a AEG DISHWASHER FAV65060IM (91123508800) an had the same issue. No hot water. As usual the repairers do not guarantee that it would be repaired and don't give you the repair time. So the solution was to give it a go. I opened the dishwasher and voila. The PCB board was burnt like the picture. I Soldered it and is working like before. Thanks a lot, it is worth it always to try out something by yourself</p>
<p>We had this on an Electrolux ESP 6241 and this solution totally worked...can''t believe it just took a bit of soldering to fix. </p><p>I now have a very happy mother in-law who can't believe I fixed her dishwasher. Many thanks for posting the instructions! </p>
<p>Did the &quot;big&quot; soldering in 2007(40850 - 2004 model), has been working untill a few month ago. Periodically would not heat/dry.<br> Found a bad soldering, hope it works now.</p>
<p>THANKS ! This worked a treat. Model was slightly different so the circuit box and clips were slightly different but the concept was the same and the solution worked well. The kids are pleased to now be relieved from handwashing duty!</p><p>Much appreciated. </p>
<p>Had the same problem on my Electrolux ESF 6221 (namely the water would never heat up and the dishes would end up being washed in cold water)</p><p>I followed the instructions exactly (the pictures and setup of my model was very similar) and now it works again!</p><p>Thanks a lot for taking the time to put this up!</p>
<p>Hi,</p><p>I have the very same dishwasher that i suspect has the same issue, the dishwasher will intermittingly switch on, do a cycle but then wont switch on again. I tested all points for power (ie: main switch, door lock switch, control board), all recieving 240V, but cant switch on dishwasher. I can't see any visable pitting / burn marks on the relay, but see slight burn marks on the brown resistor and 82/1KV diode as shown in picture. Did you change the relay in the board or just resolder. What should the correct reading be on these components, and where do i get replacement parts in durban. Any advise welcome.</p>
<p>It worked! Thank you *so much* for taking the time to share this; you saved me!</p>
