  1. Copy and paste it into search engine. ratty
  2. Shades of Coffee are advertising they have some due at the weekend. if you leave your email address on the site they will let you know when they're available, according to the website.
  3. If your Classic is pre 2015 it is hex wrench key adjustable in the top of the OPV. Pull off the tube, take off the top nut (17mm socket) Unscrew the pressure bolt with a 5mm hex key wrench until the measurement from the top edge of the OPV to the top of the adjustment bolt measures 11.5mm. Now you are in the ballpark of 9 bar pressure. Put top 17mm bolt back on and tube. Test pressure with a gauge fitted to the portafilter (can be loaned from the forum) to test current pressure in the system. Adjust as before if slightly out from 9 bar pressure on the gauge. Clockwise on the 5mm
  4. Not much, you don't get a boiler full just the expansion valve's water easy to mop up. I just added an edit to the previous post btw Don't be like me and keep forgetting to put an o ring on the valve. It's great fun having to take it off again and redo it!😭 ratty
  5. Yes, fairly easy, using correct tools. Initially long arm hex key and once bolts are slack I use a socket with a hex key attached easy to reach hand in this way and quickly turn socket as you don't need to attach the ratchet wrench to the socket. To put it back on I find it easier to hold the bolt in the socket with the hex key attached, and by hand screw in the bolt. For final tightening either put on the ratchet wrench onto the socket or use a long arm hex key. Don't forget to let the machine cool down first though!

    Refurbished 10/2003 Gaggia Classic This is the last of the four Classics I have recently refurbished and it’s come time for the wind down for me! I have one more 2003 I haven’t started refurbishing yet and it will be ready for sale in a few weeks. This 10/2003 is the best of the four I’ve just completed, with a couple of extras supplied and therefore a bit more expensive at £279 plus £15 P&P Complete strip down descale and overhaul, including boiler, group head, OPV, solenoid valve and steam valves. Replacements fitted where required and tubes and pipes cleaned checked or replaced All new O rings and gaskets fitted and they’ve been coated with Molykote 111 silicone compound, a food safe lubricant used to extend life of elastomar materials New 316 grade stainless steel bolts used almost throughout or marine grade stainless steel when available They were all fitted with a high grade lubrication/anti seize paste to resist galling and corrosion and make it easier to remove them if needed. New front panel pressure gauge fitted, set and checked. OPV after overhaul, set at 9.5 bar (drops to 9 bar at group head as normal) Modified steam valve. New Rancilio steam wand sourced and fitted. New Cafelat silicone group head gasket. New shower screen holder/diffuser. New shower screen. New outlet pipe fittings New stainless steel outlet pipe. New higher temperature steam thermostat fitted 155°F rather than the 145°F, helps for improved frothing milk. A 1425W 2004 boiler fitted and the higher rated 65W original light brown Invesys pump. This pump was the only one out of the four tested that stood up to the long term time testing I like to perform for reliability. This cannot be guaranteed though due to the age of these pumps so I am providing a spare pump too. It’s another 65W pump, an original Eaton pump 65W also fully working. The Solenoid valve is the original larger Parker made valve, stripped and descaled I have modified the steam valve as FairRecycler has recently popularized and described. New O ring fitted and the valve’s spindle can now be accessed and unscrewed by simply undoing the locknut behind the steam knob. The steam valves have been previously unreliable due to constant leakages sometimes happening almost from new, and this modification cures that problem giving access to the steam valve spindle and O ring. The case is in perfect condition any marks showing on the pictures are either finger marks or water streaks that can be removed. The double spouted portafilter spout is the type that can be unscrewed (see pic) for cleaning purposes of the two channels The channels can hold oily ‘dry’ coffee residue that can transfer into the cup on subsequent shots and they are difficult to clean thoroughly on the ‘solid’ double spouts. The double spout itself is removable if required and has been removed, threads cleaned and replaced. The portafilter is a 2007 one that’s had the handle removed, cleaned and a new stainless steel bolt fitted. It comes with a new double non pressurised ridged basket. One double pressurised basket with a perfect crema pin and one blind basket. The pressurised basket is black inside as its been left soaking in Cafiza too long, or held over the gas stove for cleaning purposes (not recommended) (Not me officer honest!) but still works I guess (I’ve never used a pressurised basket!)The middle hole is clear, the only hole there is in pressurised baskets. Also a Gaggia plastic tamper and a plastic measuring spoon supplied. This will be packed in a Gaggia box (different model box) and sent by Parcelforce 24 fully insured, the same as the three previous Classics. Best priming operation to use at the start for new owner provided. Price £279 plus £15 P&P

Refurbished 08/2003 Gaggia Classic I’ve put this for sale £20 cheaper than the last two I sold recently as I slipped with the dremel and scratched the front slightly above the pressure gauge (shown in photos) opening the pressure gauge opening. I also stabilised the back shelf with two small 3mm button head hex bolts as one of the spot welds was loose, a fairly common issue with older Classics.

I have modified the steam valve as FairRecycler has recently popularised. New O ring fitted and the valve’s spindle can now be accessed and unscrewed by simply undoing the locknut in front of the steam knob. The steam valves have been previously unreliable due to constant leakages sometimes happening almost from when they are new, and this modification cures that problem giving access to the steam valve spindle and O ring.

Around 2005 the stainless steel case was reduced to 1.2mm thickness I assume for cost savings. This made the cases weaker resulting in more twisted cases caused by the years of locking the portafilter into position; meaning the pressurised water would not flow flat over a parallel surface on the tamped portafilter basket. This could cause channeling through the coffee puck and therefore produce an inferior espresso.

  14. I like to run the pump with a blind basket in the portafilter for a full minute to check the pressure stays stable on the front pressure gauge or if that's not fitted, on a portafilter gauge. Most of the old brown Invensys cannot maintain this stable pressure that I've tested. The Invensys pumps are non repairable unlike the Ulka pumps where the pyrex glass ball can be checked for size and replaced if needed, also the o ring and seal.
  15. I've been refurbishing some Classics with the old light brown Invensys 65W pumps that were installed. Although still working in a fashion the vibration and noise was appalling. Not only that but when I did long term blind basket pressure testing neither could keep going and started mistiming and spluttering. The machines were much quieter and the pumps more consistent when I swapped them both for Ulka pumps and unless you are adding a dimmer switch the 48W is fine for the pressure required through the system.
