Dishwasher servicecode 60

The PCB is mounted just below the buttons
Our Husqvarna dishwasher QB 6221 stoped working and displayed the servicecode 60. The washer stops dishing and the pump empties the washer.

After some Googling I found some Guys who have had the same problem and it indicates overheating. It also seems that many modells from both Husqvarna and Electrolux shares the same control electronics.

So after some checking it was clear that the relay have burned and is continusly closed. The relay seems to aktivate the heater and therfore the overheating problem.

The burnt relay
In a former project I used a 12V relay from Kjell&Company (item no 36 102) and the electrical specifikation was similar to the relay mounted. To my great suprice it even fitted to the PCB with the right pin-out

So after the change of relay the washer now have been working for 2 weeks.
