Gaggia Class good or bad choice
« on: July 10, 2017, 04:15:09 PM »
Was looking around ebay today, as you do and before i knew it i had put a few bid on a Gaggia Classic with a fault

I may of got a bit carried away and ended up winning the auction, cost me paying £66 + £6.99 p & p

it was a faulty unit, which as a pump issue, which acorning to the seller makes a loud rattling noise and draws through water at a very slow rate

i think it may need a new jump and a good descale and clean, may i right in my thinking

did i make a large mistake and end up paying far too much for the unit or have i paid a good price

New pumps are cheap.   But in my experience when they make a loud noise and don't pump much water it means they've been sitting for a long time and the rubber valves in the pump have stuck closed.  Simple to take it apart and free up the two little valves and then it'll probably pump again.

The rubber mushroom with the red arrow is easy to get to and it is usually the one that is stuck in my experience.  The ball with the blue arrow is more difficult to get to and usually you don't need to get to it.

It is also very annoying to chase around on the floor when it goes rolling off the table...

May just buy the replacement pump to be on the save side, as i do not the history of the unit

and may not of been told the full story, will also save me having to replace it further on down the road

I'd wait until you have the machine before you start ordering parts.   It could be any number of things.  Maybe it simply needs to be primed (you have to get some water up into the pump first before it can pump).  The boiler could be completely filled with scale - maybe they never cleaned the shower screen and it's completely blocked with nasty, old coffee goo.  I've seen these situations more often than I've seen a bad pump.

Frequently these machines sit in someone's basement for 10 years without use and then someone cleans the basement and puts it on eBay without knowing how to use it or test it out.  So I wouldn't assume it's a bad pump just because the seller assumes it is.

Was thinking of dis-assemblng it and giving it good descale and clean anyway

may also replace the gaskets while im there, if it is the case that it has been in a cupboard for year's there a good chance the gasket will of proberly have dried out and may of also cracked, so proberly be no good, will get a better idea once i have dis-assembled it and had a good look inside and found out what is going on with it

It is also very annoying to chase around on the floor when it goes rolling off the table...

Or when it gets catapulted by the spring when you release it from its cage and it flies across the room. I've learned well enough to disassemble Ulka pumps on a cloth, ie. microfibre. The ball won't roll far, if it does, and sometimes I'll trap it in a bowl or the middle of a roll of tape.
