Bought a washing mashine (and a fridge which is not the topic) from Electrolux in February this year (2 years warranty). In October, when switching on, the display started to change settings by itself like hell, no chance of making a setting whatsoever. For me (ex-service technician on Lab-equipment) it was clear that it's either the display or the motherboard.
After reporting the issue, it took 2 weeks until two service technicians showed up to tell me that they have to order a display and a motherboard. They said it will take 1-2 weeks for delivery and repair. So far so good...
After 3 weeks I ask them when the repair would happen. As answer I get "Now I already complain to head office".
I know from my own experiences on the job, that also new equipment can break down, especially electronic parts. Thats not a problem for me.
But after this knowledge with their "after sales" I guess I'll change my decision. Wanted to buy a tumbler and a induction hob (total around 40k bht) already choosed what models.
...except if somebody might tell me that all Thai companies don't care after they sold their home appliances.
