DavecUK I checked because not all of my questions have been answered
If you check again you will see that I attempted all the tests specified and answered all of the points in your post in the numbered paragraphs
The only test I didn’t complete was removing the black capped compnent in the centre of the steam boiler, as I explained
DavecUK Is the water constantly dripping into the drip tray from that little outlet, or only when it warms up. If it’s constantly dripping, is it coming from the vacuum breaker.
It drips when both Brew boiler and Steam boiler are warming up. I speculated in my post tonight that the ECM is clearing the water already remaining in the clear hoses from the last session.
It trickles steadily when pulling a shot with the blind filter in. The video shows this better, but I can’t see how to upload it here. Its 19 secs, yet too big for the upload facility here.
I bought a whole new vac valve assembly, and replaced the old one on Thursday night.Since fitting it I can still see air bubbles passing along the hose from the vac valve as the outlet trickles steadily into the tray.
I’m going to descale before I commission it for use, so I’ve run maybe a litre s through it in total, in two sessions since then to test it, using ordinary tap water.
