Delivery super, washing machine apparently well after initial difficulties

Too great experiences I have not with this washing machine. First time for delivery via Amazon: Super! Your date has been complied with, old washing machine taken and connected new washing machine, everything worked like a charm. The washing machine itself, however, has only one day to work. The program has stopped at one minute. After a technician was on site and could not find any fault, fluff filter has been cleaned, I tried again. Same mistake again! There, a technician was sent back, which then could find a loose connection at the heater. This was replaced immediately. So far, (the now is a week ago), the washing machine in continuous use for holiday clothes. So far it is still working properly and I think I just had bad luck.
The operation is otherwise very simple and the price-performance ratio - up to the initial difficulties - it seems to have been to me a good choice.
