Does anyone here have an espresso machine with an E61 brew head?

What do you need to know? I've had a few E61 machines, still have an Isomac in storage.

No, not needing info, just my experience regarding cleaning (back flushing) on a regular basis. I have an Expobar Office Leva (aka Brewtus in other markets) and have been doing this back flushing thing every night. Even did the same with coffee machine soap in the blind filter. The other night I put a small amount of soap in the blind filter, did a couple of back flushes then left it like that for an hour or so to see if any of that oily residue might not perhaps gets flushed out after soaking in soap for a while. I was quite dismayed when a lot of dirt started to appear in the water released when I closed the valve. And it just kept on coming out. Must have taken upward of 30 flushes before the released water was clear again and no dirt (by want of a better word) was present in the blind filter when I took the portafilter off. Just thought I should share this if anybody here has an E61 machine and who, like me, erroneously believed that back flushing is sufficient. It's not, soaking seems to be important as well, but I have never read anything about that on any of the coffee forums I frequent, nor in the machine's manual.

I am not familiar with your machine,but what you experienced plagues all espresso machines using a portafilter/basket system whether E61 group head or not. Using a blind filter and detergent to back flush tells me that your machine has a solenoid valve of sorts. This is not a bad thing by any means but in some machines a proper descale is not possible without a complete strip down. In your case I suspect the shower filter in the group head is clogging up with coffee grinds.

In certain machines shower filters are either a flat metal disc with holes or a fine wire mesh,in other cases it is a shower cup similar to the coffee basket. Either way these showers need cleaning and while you are there the group head can be cleaned as well.

In barista training I always instructed students to run water through the group head after every coffee shot they (pulled) made. This way clogging up of the shower screen was minimized.

@gapco
I only wanted to make people aware that back flushing on a daily basis as well as sometimes with soap does not clean the shower screen and gasket, in fact all parts in the group head coming in contact with coffee; one needs to allow it to soak for an hour or so with soap in the blind filter as well on a regular basis to ensure a clean brew head - I do it on a weekly basis now. That coffee gunk has a very bad influence on the taste of your espresso.

Yes, my machine has a three way valve as is usual for this type of machine.

Thanks, I will alternate hugs between the missus and the machine.
