    How fresh is the water in the tank?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I read recently in the book "Been there, drunk that" a comment about emptying the water and re-filling with fresh water in the tank of your domestic coffee machine every day to avoid mouldy tase.

    I thought I was doing the best I could by using filtered water, and dont feel right about throwing it out every day.

    Has anybody got some thoughts on this subject for those of us who typically use the machine once a day to make couple of drinks, most days, and maybe several drinks once or twice a week.

    I have Silvia and have thought of letting water level run about half way in the tank, which means most of the water gets replaced about every second day, by the time you pull a couple of shots and run some flushing water through each day.

    But also like the idea of keeping tank near full to minimise risk of running boiler dry if you forget to top it up one day!

    Slightly off topic, but has anyone got a reliable and reasonably cheap way of monitoring the water level in those tanks that are out of the way and need the lid lifted to check?

    Hmmm,

    Sounds excessive to me too Bullit. On average, the Mokitas reservoir gets refilled every three days or so with water filtered through the ubiquitous Brita Jug. I wash the reservoir out with a stiff bristle brush and dish-washing liquid every month or so. To date though, have never observed anything growing inside it or floating around in the water :o. Sounds like the bloke from BTDT left his reservoir sitting out in the sun for a few hours every day :-?,

    I leave water in the reservoir at a minimum, and simply top it up by the approximate amount I am going to use, at each use. So...I check & top up before each use.

    By the way running the reservoir dry does not run the boiler dry...it runs the pump dry!

    A very simply float arrangement will give you an idea of the water level without removing the lid. EG....get a piece of cork, stab it with a timber dowel thats had one end sharpened like a pencil, chuck it in the reservoir, drill a hole in the lid, feed the dowel through the lid as you put the lid into place and whalla....the cork / dowel arrangement floats up & down through the lid...disclaimer: this idea is subject to refinement!

    Regardz,

    I hadnt cleaned the water tank for about 3 months and when I took it out to have a look, it had black deposits at the bottom :o

    Probably not mould, maybe metallic in nature. Ill check more often from now on...

    Thanks for the feedback/comments.

    I think I will go with the monthly cleanout as Mal suggested, and in between run about half a tank so it is going through the unit.

    FC your idea for cheap water level indicator is, um, cheap, and would probably work well.
    I had something vaguely similiar in mind, although would prefer some sort of sight glass, but couldnt see how a sight glass could be fitted without making the tank non-removable (not good) and then all the way to things like electronic level detectors, which I believe are fitted to some of the more expensive HX machines.

    about once a month, I (used to) take the tank out and give it a good wash ... a bit of bleach inside, thorough rinsing and drying.

    but then I found out that I can run the lines from the tank the the pump out of the machine, and into a 12L bottle that sits under the bench. Easy to see the level, refill once every couple of weeks, and I can leave cups on top of my machine now!
