A good user manual. The rules should oblige the seller to give the purchaser an operating instrucion of Electrolux ESL 46010, along with an item.
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. 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! Dishwasher broke down 5 days before Christmas - not heating the water. I followed your instructions and removed the circuit board, but was disappointed to find that it looked in perfect condition. I decided to just heat up the four legs of the relay and add a blob of solder to each pin. I reassembled everything with little expectation of success.
But it worked!! I had already sourced a replacement Bosch from our local Curry's, so to save £350 at this time of the year is my Christmas Miracle!!! Thanks again. This was amazing help! Yesterday my wife recognized that dishwasher is washing with cold water. An Electrolux ESL46010 was running for 8 years without outage.
The disassembly was a little different and cables were glued to inner stainless front wall. After dismantling of PCB i have soldered and bridged by solder the marked critical points of 12V relay 10A~ contacts. After assembly, the complete electronic didn`t work.
Waited to calm down and advice of my wife, that maybe the display/buttons board isn`t connected. Plants vs zombies zen garden. Today i again completelly disassembled the control box and 'THAT WAS the fialure!!!' Small click of pcb side connector on ribbon cable, and IT WORKS AGAIN!!!
Many thanks for help which saved me cca 300EUR for new dishwasher. The authorized repair was estimated to 150-200EUR. That was saved surely.
