Find a reasonable authorised service agency who is willing to supply the logic flow diagram for this model.
The "closed-shop" approach to this German-designed software processor is becoming notorious and un-welcome in the current climate.
The DX302SJ is a "Lemon" --- not because it can't do the stated task, but because there was a fragmented approach to engaging "Brand Loyalty".
In fact, from my research, this one has been a classic in the annals of the 'don't go there ever again' and all because of the corporate structures involved.
This brand has to be off the menu for future whitegoods releases until there is an agreement to supply adequate information relating to fair wear and tear in a household appliance. This especially applies to "catch-all" troubleshooting indications which appear to be couched in terms of safety, but are in fact, directed toward the benefit of the after market service sector.
There are plenty of well-qualified persons who can service these devices, but the shop has the closed sign hanging on all of the doors.
This also means that persons intending to purchase electronically controlled machines need to ask themselves one question:
What happens when there is an indicated issue which has no parent or potential parental genesis?
In other words, if the troubleshooting guide does not delve into the restricted zone except for authorised agents, don't buy the thing.
There are others on the market who willing supply all technical information with adequate caveats re the legal responsibitity for work done by qualified but un-authorised individuals..
Proper electrician.
