Seems like alot of people are using Gemilai CRM3605, including me

Anyone know of any coffee machine repair service in Klang valley? My machine is getting some hiccups and recently making lots of weird noises

I think usually coffee machines are quite standard, once you learn the basics. The machine itself is quite basic, decent enough to do a cuppa for its price.
But I believe its discontinued, newer models to replace it.

Yes you'll need a separate grinder, you can invest in a good hand grinder first before splurging on the expensive electric grinder. Or just buy off shelf ground coffee
