When you come from Europe, in most cases you'll make choice for front loader as the Siemens you have.
I owns also a Siemens and it is still okay after more than 12 years in use.
You'll have to know, Siemens, Bosch and some other brands al coming from the same factory and all have a better than average quality.
A machine similar to what you have now is the Bosch WAT28360 and is available at a reasonable price, from 13,166 until 16,000 THb.
