In the last month began our washing machine story that just closed
nowdays. After 6 years intensive usage our washing machine went wrong from one to another day during an ongoing washing program. When I wanted to turn it on there wasn't any led which showed any little sign of life in machine. I have unconnected it from the socket, moved the plastic parts until reached the CCU board and cables. Connected to the socket again and very carefully tested the cables with voltage tester. After very carefully testing fixed that the cables are good, but the electricity is vanishing some way on CCU board. Then I have called a familier washing machine mechanic - for who after telling him the full story and the problem is on the control board - automatically suggested to throw out the whole machine. Because the error code can be just read by laptop, control board is not fixable only replaced by service, can have more problems etc.

After a little research on the net it was clear to buying a new CCU board is not an option, the result is buying a new wasing machine. I did not want to accept it. So just surfed through several forums and webpages, was reading about diagnostic tests and possible malfunctions until came in front of me that somebody posted and wrote a choke that was kind of destroyed on his board. I've checked my board and according to the attached photos found that having the same issue. Okey let's move in this way :). After a small research on the net I have just found a very instructive description and the solution, to my suprise on ebay.

Step 1: Fixing Whirpool AWE2519 Washing Machine

So ordered from here:Repair KIT Whirlpool Laden Ignis LNK304 R020 L1373 L1782 L1790 L1799 L2158 L2524

So:

If you are looking at my auction it means that you have an issue with a defective Control Board in the washing machine or dryer Whirlpool, Bauknecht, Polar, Laden, Ignis brand.

Boards have marking L1373, L1782, L1790 (dryer), L1799, L2158, L2524. Pictures of boards in the gallery. In these machines power supply gets burned very often. The LNK304, 22Ohm resistor (or 33Ohm) R020 and L003 0,47mH choke (470uH) are burnt like on the pictures. . Thanks to my set repir kit you can save a lot of money!

I worked in the electronics design department in Whirlpool (in Poland) and dealt with the problems with the quality of Control Boards. They were produced by different companies. First Bitron and Invensys, then Flextronics (replacing Invensys). Board for dryers was produced by Diehl Controls Polska (marked DCP and Diehl AKO)

The programmer has been used in many models of washing machines Whirlpool Bauknecht, Laden, IgnisAWO AWE AWD / eg. AWE4316 / AWO / D41105 / Polar PTL 1000 pfl 1019 Whirlpool dryer AWZ414 and many other power supply which is based on an integrated circuit LNK304P.

Can cope with the repair?

Repair does not require any special skills, and certainly those who used the soldering iron will manage the rapir. To repair soldering is required if you do not have your own ask your friends. Repair is succesfull in 90-95% of the cases, so it's worth a try!

Diagnosis of Damage:

If the machine is completely dead, when you turn lights nothing we suspect damage to the Control Board. Typically, the inverter is damaged LNK304, resistor R020 and L003 choke. Sometimes the diode D029, D030, D006 and varistor RV07. We also recommend exchanging our electrolytic capacitors, better quality, to extend the life of the Control Board.

Remember that before getting to the Control Board unplug the machine.

Reason for failure:

You can read ead a lot of information how manufacturerers design deviced do break just after warranty period. Well, there are two causes. These Control Boards were designed in Italy and unfortunately were one of the greatest failures Whirlpool, which cost the company tens of millions of euros. And the second reason is the excessive emphasis on the savings and usage of components with the lowest possible parameters to ensure correct operation.

.. so just ordered the repair kit. In the envelope psokol78 put an instruction that helped me identifying the items on board and gave useful suggestions how to fix it. On photos below you can check the burned L003 choke, the steps unconnecting the board from washing machine and the received instruction paper. Unfortunately I have forgot to take photos after the successfully installation and about working washing machine but when I am typing this rows we are over half year successfully washes.
