  1. Hey nice work!! I see this was done some time ago. I’m looking at the same for my Profitec Pro 600 vibe pump as I want to also plumb it in. looking at the parts list for the pro 700 that has a rotary pump it seems to be the 50L flow rate model with a 120W motor. Any major issues to avoid? I noted you used a pressure reduction valve from your mains. What is that for? (Beyond the obvious) best Simon
  2. Oooh !! Fascinating- so effectively what I would build from my 600. Love the ECM valves also
  3. Learned friends - for likely reasons of curiosity more than practicality I am considering a mod and upgrade to my 600. Swapping the vibe pump for a Pro 700 spec rotary (pump external to machine) and then plumbing it through a filter. Many might ask why not trade for the 700. I guess the answer in my head is it being a little more cost effective, staying smaller in chassis space (not sure how much actually)… being quieter with pump remote within the kitchen cupboard, and probably because it is a project. reviewing the spares manuals and reading others than have done this to different machines it isn’t ultra complex, but expect there are some niggles to iron out. Thoughts? Total waste of time? Major blockers on changing the pump types? let the abuse begin.. 😆
  4. Hi - mine is typically on for an hour before I brew. I purge the steam wand first to rid the condensation. Then brew, then wait a bit cleaning up etc, then steam.. that seems to work best for performance. if I were to brew, then immediately purge the steam wand and then steam the machine would run out of puff quickly and struggle to steam one small pitcher.
  5. You are not talking nonsense.. it tends to flash often and there is a decimal per boiler linked to the temp changing between the two boilers. Pretty hard to track though and I think blinks even if not heating. Need to confirm that..
  6. Late to the reply.. I have checked and naturally have no f.02 mode of 5 available. Checked the power draw for each boiler on UK mains. 1.1kw each. So effectively both boilers could be on at the same time on a 13A connection. Guess no way to mod this? I might future mod to provide indicator lights for each boiler. At least that way I clearly know when I can steam.
  7. I’m not sure how much this is covered elsewhere but read and have proven that my own Profitec steam performance is much to do with the timing of the PID and only one boiler permitted to be in at a time. I have tested now (after a year of slight frustration) and when pulling a shot, I then steam milk. The issue is that the machine has prioritised the brew boiler and spends 10-15 seconds or so heating it back to 95 in my case. if steaming during this time, the performance quickly falls off. The reason - no heat boost. If I wait and confirm the brew boiler has stopped, the steam performance is much better. I’m going to look into whether both boilers can be allowed on at the same time (current load I assume)
  8. Breaking news! I have cleaned my machine and perhaps have noticed some small gains in crema. All of my coffees are milk-based. The report: Removed shower screen. It had a reasonable coating of black residue, easily wiped. Similar for the grouphead distribution plug. Removed Mushroom valve, spring and first valve in the group head above the cam. Very minor limescale. Soaked and cleaned in de-scaler and then re-assembled. Then backflush around 12 times using Cafiza cleaning powder.. I got some 'brown water' and clear quite quickly. Flushed a tank full of water through the machine. Took the plastic pipe from the steam wand and cleaned that and the dual hole tip (both were clean anyway) I have not taken the cam lever out (lube on order to do that), or the exhaust section of the E61 GH. My steam valve has a slight weep (not sure what to do about that). In general. While cleanliness is next to godliness and we all have a range of these things from hobo to OCD, I was not too shocked by mine, it was mostly 'almost new' with the exception of the shower screen. Bought some Grinder cleaning 'pellets' also to try next Cheers
  9. I have been using Ashbeck, lots of aqua pura I think it was called (5l in a large container) and latterly Volvic
  10. Is that a rhetorical question? My assumption was that one can fiddle too much with a machine, and using bottle water I shouldn’t have much like scale issues. The grungiest part is the group head screen and quickly cleaned.
  11. I have had my Pro600 for over a year, used three times a day since lockdown began. I have done a few backflushes. Removed the screen from the group head and cleaned maybe 5 times. Never descaled. Always used bottled water. is there more I should do? Should I descale? My steam valve has a slight weep now. I have re greased that. Otherwise nothing taken apart or played with. All seems fine. I did remove the water level sensor in the steam boiler for another reason and while it had a light clean, it and the boiler internals looked good. just wondering..
  12. I’ll be fascinated to know how you get on. I have a Profitec p600 and really liked the levers on the ECM Synkronika
  13. Hi - my auto fill is pretty random. It will do it when the machine has been standing for hours.when first frustrated with this, I got around it by triggering a refill by using some of the hot tap and this forced a refill. latterly I am using a decent steam wand purge where I get some water out and this causes the boiler to re pressure and most of the time it’s ok.. at least this way I get steam power. Before this, even if the boiler didn’t refill, I could run out of puff before steaming one drink of milk (flat white not latte). Hence not being impressed. I did mention this to the support team at Bella Barista but didn’t get that far with them. I think I expected or hoped that there would be enough capacity (steam) to comfortably do twice a milk load (two drinks, one jug) easily and without thinking about it. realising I didn’t answer all your Q. Steam after brew. Hence I now do ‘steam purge’ grind, tamp, brew, then steam.
  14. Hi! Well it has had a LOT of use with the lockdowns and so glad I bought it. Overall, very happy. The only thing I would change is the steam boiler size. Sometimes it blasts other times it will refill itself mid milk steaming. I have started a routine where I purge the condensate from the pipe before making espresso. I get a good tablespoon or two of water and this makes the boiler element kick in and get the steam back to 2 bar (I set the Max steam temp with the PID). It will still sometimes do a refill of water while steaming which is annoying. That’s my only gripe. im starting to get a tiny bit of water seepage on the valve stem also now. Only when rotating the knob will I notice a few drops now and then. I guess the steam seal is just starting to let a little get by. Perhaps a side effect of me cranking up the steam pressure from the factory setting. I did buy a decent naked PF and basket which seemed to make a lot of difference.
