  1. Hi Frank... thanks for your reply. Yes, I suppose I do shut off pretty quickly. I'll try it more slowly, but I still think my running the pump for a moment is the way to go. The screen is washed by this and the puck drops cleanly from the basket. No knocking required, just turn the PF upside down and the puck falls out. I always ran the pump briefly anyway, after the PF had been removed, to clean it with kitchen roll paper.
  2. What I'm about to say should be obvious to everyone, but although I have owned a Verona for over four years now and used it daily, it has only just occurred to me. I’ve been experiencing quite a lot lately the spent puck sticking to the screen and the basket coming away empty. It varies, with some beans more inclined than others, but my current batch (Columbia La Crystalina from Rave) is particularly bad in this respect. Releasing the portafilter gently and finding it empty, I have carefully hooked it back on again with the best positional accuracy I can manage then partially released and jiggled it around vigorously in the hope that on the next withdrawal, the puck would be in the basket. Invariably there would be coffee grounds spread over the edge of the basket and in the portafilter securing groove of the group head... a bit of a pain to clean... not to mention a very caked up screen. But now, I release the portafilter by twisting the handle a little and then run the pump for one second or less. Result - puck nicely in the basket, clean screen and on emptying the basket the whole puck falls out cleanly with barely a trace left. I can't imagine why I didn't think of this before; it's so simple and obvious. Am I the only one who hasn't twigged until now? By the way, the Verona is superb. I can't think of any machine I would prefer over it. Its only minor failing is that the water tank can run out without warning and the machine stop dead in the middle of a pull. Some kind of low water warning device would make the machine absolutely perfect. Tony.
  3. Hi Markk. Thanks for your post. My Verona was bought shortly before the PID Timer Mod. But the Steam boiler does appear to be 'stainless steel pale grey' - at least, the top plate, as the cylindrical wall is covered with insulated cladding. I wouldn't have noticed it, but when we had the machine apart for the pump job, I had DavecUK's 'Closer Look' article open on the iPad, and viewing the 'innards' photo from the LHS, the colour difference was immediately obvious. I didn't look at the Brew boiler, so can't comment on that. I presumed it was still brass. At the time when the timer mod. came out, I felt a bit cheated, as it wasn't retro-upgradeable. But I now use Brewista scales with integrated auto-timer, so there's no need for the PID one. Very, very happy with the Verona. I firmly believe that given the choice all over again, I'd go for exactly the same. Well done Sir, for for reaching the same decision yourself! Tony. Addendum: One thing I wish had been included was a warning that the water tank was getting low. The number of times it has run out and the machine shut down during a pull... infuriating!
  4. I wholeheartedly agree Dave. My fault entirely and most remiss of me. Rest assured that my maintenance schedule will be much more rigorous and frequent than hitherto. Hopefully I have got away without any permanent damage... just shows what excellent design and manufacturing quality these tough Veronas are! Tony Addendum: By the way, the steam boiler which I believed to be made of copper, appeared to be of S/S if the grained appearance and light grey colour of the top plate is anything to go by. Is that the case? The machine is 3 years old.
  5. Hi All who responded to my non-running QM Verona pump plea for help. In the end it turned out to be excessive scale that had seized the pump. We removed the pump and freed it off by turning it gently with a spanner and eventually running it slowly with a vari-speed power drill. It was then refitted to the motor and it ran OK - no need for a replacement. Since then, the whole machine has been thoroughly descaled with citric acid and is now performing perfectly, the pump running as quietly, if not more so, as it ever has. We also dismantled the Group's lever mechanism, polished the surface of the cam and lubed throughout with food-grade silicon grease. Lastly, the whole machine had a much needed clean and polish with S/S aerosol foam cleaner, and the whole thing now looks and performs like new! Great machines, these Veronas... so glad I made that choice. I now have the pump pressure sitting exactly on 9 bar during a shot (temperature 196°F / 91°C) and the static steam pressure bang in the middle of the green at 1.25 bar with a steam boiler temperature of 254°F / 123°C). During milk stretching, the pressure drops to 0.95 bar, but that I think is because I have chosen to use the no-burn wand and the 4-hole tip. I have no issues with heating the milk though... takes about 20 secs for around 70ml of blue-top milk. Being of an age where degrees Farenheit makes as much, if not more sense to me as does Celcius, I have opted for °F on the PID's display, for the display's °F resolution is twice as good as °C. My grateful thanks to everyone who chipped in to help, especially to El carajillo, with whom I communicated extensively by PM and 'phone. He helped me enormously in the dismantling process and with numerous pieces of excellent advice. Tony.
  6. Hello Dave... thank you for your prompt reply. Yes, I'm sure the pump is not turning. I don't think there can be a blockage, as I have used only commercial bottled water which has always seemed clear and pure. The pump could have seized - I have never lubricated or serviced it. It could equally be a leaky or failed start capacitor. I presume it will be electrolytic, and if so, will have a finite life. If your gut feeling is that it is not a build up of scale, that's good enough for me... I'll look elsewhere. Thanks again. Tony.
  7. Thanks Espressotechno. If it does prove to be a scale problem and descaling won't fix it, I'll go for a new pump. The pressure gauge used to show about 10 bar, but recently, this has dropped to about 8. Tony
  8. Thanks Grumpydaddy. If all else fails, I'll try that. Tony.
  9. Hi All, I have a problem with my three-year-old Quick Mill Verona insofar as the rotary pump has stalled/seized. I can hear it electrically buzzing, but there is no rotation. I'm pretty sure it's not an electrical fault but excessive scale build-up within the pump head as it is well overdue for a descale. But this creates a Catch-22 situation. I can't flush descaler through the machine if the pump won't run, so how do I get round the problem? I know I should have descaled sooner, so it's my fault it has happened... any advice gratefully received. Thanks in anticipation. In all other respects, the Verona is still superb. Tony
  10. Deliverance. Burt Reynolds, Jon Voigt. Saw it ages ago, but was well worth a second veiwing. Tony
  11. God said to Noah "I want you to build another Ark... but this time, I want a really big one; huge; massive; twenty stories high". "But I don't want any animals - just fish. And not any old fish, only Carp". And Noah said "J-just a minute, you want me to build... . . . . . . . . . . . . . . . (wait for it) . . . . . . . . . . . . a twenty-storey CARP-ARK?"
  12. Three kinds, 500g of each. Peruvian Tunki - my favourite single-origin, Indian Tiger Stripes blend and Breakfast Favourite blend - both delicious. Roasted 12 days ago, actually received 11 days ago and at their prime right now. The Peruvian Tunki, freshly opened today, yielded one of the nicest cups I've ever tasted. I pull 34g liquor from 17g ground beans in 30 secs. or so and add stretched blue-top milk at 55°C. Yum. Tony.
  13. Make sure the rotating burr, the lower one, is perfectly centred... there's a bit of lateral slop to play with from the securing screws. A micrometer type dial gauge helps here. Tony.
  14. My Amazon Prime delivery chappie brought a flying hi-res camera - in the form of a DJI Phantom 4 intelligent quad-copter. Nothing to do with coffee, but pretty exciting anyway. Between it and the Yirgachaffe I'm using at the moment, a most enjoyable buzz! Tony.
  15. I went for ridgeless. Both styles are identical in performance... the ridged version being a little more difficult to remove from the PF as a spring on the PF locks into a groove (the 'ridge') on the basket. Ridgeless have smooth sides with no indent and the baskets slide out of the PF smoothly and easily. I much prefer that. They are held perfectly securely by the spring even without the ridge. Hope this helps. Tony.
