Mara X descale/service needed with Osmio Zero water?

Badgerman

Hi All, been on a few coffee forums over the years and have had a Mara X (first batch nearly 4 years ago!) and OZ based on @DavecUK reviews - cheers!

I clean and change the filers of the OZ as per recommendations. I don’t add anything back (bicarb etc) in to the RO water from the OZ to the MX.

I back-flush with water daily and clean the group head monthly with Puly Caff and have done the OPV mod. Only use it in coffee priority mode. 3 milk drinks daily.

Do I need to descale or do anything else service wise with the Mara X. It all seems fine other than it does heat up quickly (the LED stops flashing i.e. ready after 12-15 mins rather than what I thought was 25 mins).

Thanks in advance for any advice.

Badgerman You won’t need to descale…ever. Just take the case off every 6 months to 1 year and have a look around…fix what looks like it needs fixing.

Thanks @DavecUK - should I be adding any minerals to RO water? Bela Barrista said it’s not good for the temp probes to be in RO water all the time? They also offered to service it for £300 which seemed a bit steep as pretty handy myself.

Badgerman Not for the water from the Osmio Zero, you don’t have too, but if you want to add a very tiny amount of bicarb, you can.
