Subject: Problems with removing the detergent taste from Expobar Brewtus
 

Hi all,

we recently bought Expobar Brewtus IV, and it's been doing really great, but right now we're having a really strange problem with it. After coming back from holidays, we did the standard back-flush cleaning (with the detergent powder which we bought from the same shop where we bought the machine). We put 1 table spoon of the powder (as indicated on the box) and backflushed it for several cycles, and then did the back-flushing with only clean water for several cycles in the end. Nevertheless, for 2 days now we just can't manage to remove the residue of the detergent taste from the machine. We first noticed it in the taste of coffee, and then tried the water itself, and it indeed had a strange taste (bitter/sour). We made sure the taste of water is not coming from the water container, nor is it coming from the pipe linked to the second boiler, nor from the portafilters. We rinsed the machine so many times, and backflushed it repeatedly (I have a feeling we've used some 20 litters of water by now), but the bad bitterish taste still remains in the water that comes out. The machine is completely new, so this is really depressing. Please help if you have any idea of where we've gone wrong or what might help. Thanks a lot in advance!

Usually, prevented by the 3-way-valve, the detergent should not get into the brew boiler during backflushing. I understand that you tried the hot water from the tap and it tasted bad as well. So, maybe you should complain about your problem to the dealer, because something might be wrong with the magnetic valve. After all it's a new machine.

Thanks for the reply NobbyR! Actually, now we tried to flush out the water from the second boiler again, so through the tap. Near the end of flushing a whole layer of thin white sustainable foam came out! So now we are wondering whether it could be the case that the detergent somehow entered the second boiler though the backflushing process, and is influencing the taste of the water coming through the first boiler... Would that mean our machine is actually having a malfunction as you say? The foam always comes only at the very end of flushing the water this way (i.e. through the tap).

Are you talking about the steam boiler? The brew boiler and the steam boiler are not connected (exept for the water tank). So backflushing definately should not effect the steam boiler.

Oh I see, then this white foam from the steam boiler might be something entirely different.
I suppose the only explanation that the taste is still bitter is that the valve you mentioned isn't functioning well, and so some of it got into the brew boiler.

The hot water tap is connected to the steam boiler, the brew head draws water from the brew boiler.

One tablespoon? 1/2 teaspoon is what I've always used as per instructions. Is this the first time you have backflushed with a detergent? Are you sure one TB is the correct amount?

Unfortunately, the instructions do say "1 tablespoon" :-/ The product is called "Clean Express", and we used it once before but accidentally put 1 teaspoon, and that time it all went fine, no residue after the standard rinsing. But this time we thought we should do it as the instructions say, so we used a tablespoon. A bad idea, seemingly.

I haven't used CleanExpress yet, but as far as I know you're supposed to use 1 teaspoon for backflushing and 1 tablespoon per liter for soaking portafilters, for example. The picture is from an actual CleanExpress can, unfortunately it's in German only.

I re-checked the instructions and 1 tablespoon is stated in English, German and Italian version on the box, but also that 1 tablespoon should be used per 1 litter of water when washing the portafilters. So the instructions might be wrong.
Now the good news is that just now I managed to finally pull out a non-bitter shot out of the machine. It seems the endless rinsing did remove the detergent. I'm worried though for the next time... We'll certainly use 1/3 of a teaspoon as you guys recommended, but I just hope that nothing is wrong with that magnetic valve. Is there any way to check that independently, so the functionality of that valve?

Thanks to all!
