This help?

I think so. Will print and follow through all the lines on my machine, but it certainly seems like what I needed. Did I mention you are a prince among men? :thumb: Edit: Yep, that clears everything up. the mystery valve is the 'autofill exclusion valve' I have a very slight weep from the OPV, but that is probably just an old and slightly dodgy seal. Once the Azkoyen goes, this becomes its replacement and gives me a chance to monitor for intermittent problems. That will also return a corner of workbench and I can roast again.

Grimy No More! Machine is now installed and worked to pull a couple shots this am. I gave it a quick spruce up with some metal polish and replaced the cracked waste/drip cup. Then hooked up and put into service. First couple shots could probably be described as 'average' (you reading this Jeff? 😃). I do hope to improve on that, but for now I need to come to grips with different group heads, different baskets, different temperatures to what I have been used to. One group head is significantly hotter than the other when idling - problems with flow through HX circuit? Also it doesn't have a manual start/stop button. I need to use one of the volumetric buttons. To prevent premature shot termination, I will ensure the long double is programmed for a large amount and manually control using that one. It sits with element off 100seconds, then 35 seconds on - running single leg of element 1650Watts. Haven't done any tweaking yet as I want to get to know the beast first. Photos to be attached - easier to type here and add from phone later.

Looking good in the photos Lets hope you sort out the couple of remaining small issues KK

You guys and your bargain basement machines ... Kudos!

Couple quick measurements this morning. 50 minute warm up. Changed to basket I was previously using successfully in the Azkoyen, dose as I used to (17gram). Flow rate looked good. Slightly better than before, but still thin and poor quality. Second spot for my daughter looked better, but hard to say for sure. Thermocouple on the top of group head (they are e-61 groups) reads 75 degrees on the left group and 64 degrees on right group at idle. Drops no more than one degree during pour. Temp in the cup is 64 degrees. Pretty sure used to be 70 degrees when I used the v azkoyen. Wish I had a Scace type device. Next step check pressure with different gauge. I think I will raise boiler temp a bit. Need to look up pressure/temperature tables first. Currently at 0.8-1.0 bar edit. boiler pressure raised to 1.0-1.2 bar. 69 degree exit temperature measured with my 'scace' (portafilter handle with a hole drilled in side to get temp at base of filter ). That was after 30 minute warm up will leave idling a bit longer and see if temp rises, then try making a real shot with good beans rather than sweepings - have been using grinder sweepings just to get flow rate down to normal extraction rate. pulled a shot with fresh beans after another 30 mins warm up. Much more palatable but not there yet. This machine runs seriously cool and ANY cooling flush just drops temp. Tomorrow I will be trying without any cooling flush to see what happens. As one group runs so much cooler, I guess I need to research servicing E-61 group heads.

finally got a few decent shots. On for well over an hour, preheat cup using boiler water. Rinse and heat p/f with boiler water after a short flush through the filter. Load with three day old brazil/india blend. 35 sec extraction, 40gram in the cup from 17gram coffee. Well balanced shot. So next up is a bit of investigation of whats going on inside the group head and see if I can raise temp a few degrees.

Sounds intriguing!

And now Mac is illuminated. Crap pictures, but does show the LED lighting on the e-61 groups.

Do they make the coffee better ? :rofl: :stir :stir

Previously the crema was a bit dark and occasionally bitter. I now find it a bit paler and blondes slightly sooner so quite possibly. It MIGHT be subjective though, the jury is still out. Time will tell Regardless, just playing with it brightened my day which has to be a good thing

Bling done tastefully is always cool KK
