Re: zanussi zwf16070w1 door problem
This is a big “if”….but,- IF it’s the electronic doorlock which i THINK it is, then the contacts burn over time and eventually weld themselves together.
Continuing to use the machine in the manner you describe, COULD fry the main control-board.
The cost of the board makes a repair uneconomic. IIRC spares@Whitegoods has them under £20 and delivery is usually quicker than finding a local repairer/spares supplier with one in stock
