My Izzo Vivi pump (Ulka Type EX5) seems to buzz fine, up until mid-brewing, and then it seems to silence/mute down to maybe 20% sound, while still providing some pressure, though I'm guessing not exactly full pressure. It seems to influence the flow.

I just bought a new grinder...

I'm working on an older Astoria two group commercial machine. It's stripped down to the frame now, and I'm clearing out all of the lines. This one kind of baffled me. It had a little white dollop sticking out the end that looked like the top of a soft serve ice cream cone....

Still beating my head against the two group Riviera. Got most of it sorted, but still have persistent leaking once it starts to come up to pressure. What is odd is that the leaking usually stops once it's up to pressure.

So far I've disassembled both groups about eight times....

Hi everyone I'm new to the site so thanks in advance for any help.
I recently got an old isomac espresso machine and have been taking it apart. I'm having two problems
1- when I first turn on the machine the auto fill function works and refills the boiler with no problems....

Hi! Got my first espresso machine two weeks ago and just ran into some troubles with the steam wand.

The other day i was making myself some cappuchino and was unable to froth my milk due to bad steam pressure. Shut the machine down and let it cool off, noticed the two holes in...

I recently purchased a used Oscar I to replace a previous Oscar with broken boiler.

I have been having troubles with the shot times varying from 18 to 120+ seconds. Most often the first shot pulls at about 25-40 seconds, but the following shots are slow. I have noticed the pump...

A few months ago I noticed that steam was wafting out of the drip tray. It appears to be coming from the left discharge area. There is also steam that comes out of the water intake spot on the top of the machine. I have a student technician who has opened the machine up before...

Hi everybody

I've just refurbished my Izzo MyWay Vivi (2011 version) with new internal springs, gaskets and valves.
But the preinfusion valve seems to protrude too far into the cam pocket area (or, it doesn't look it, but the cam lever is extremely tight).

This is my new...

This whole pavoni was abused horribly. Amazingly, the electrics are flawless. Anyone ever encounter this issue with a pavoni group? The siphon screws in and functions fine, but the screw which is part of the whole casting it seems has split along the thread on the very edge....

Hi,
Looking for help with my machine. As the boiler was heating up there was a pop and (my wife saw) a puff of smoke!
I immediately shut it down and took the cover off. Can't find any signs of electrical fire.
Orange light comes on. PID comes on but stays at .65 F.
Red light on...
