Hi friends, I use whirlpool full automatic washing machine. Motor din rotate and stopped working yesterday. Whirlpool servicing guy checked and told that there is lot of scaling in the machine (lot of dust). He asked me to change some parts in the machine. To avoid scaling again in future I was advised to do tubclean with powder which whirlpool provides. But i din buy as i thought i will get it in outside market. I feel the one whirlpool provides is expensive. Is there any other tubclean powder available in the market?
