Hi Bryan,

Sorry to hear that the pump isn't working properly, but I don't see why it wouldn't. I followed your link to the ifixit.com website, & that pump is a 1/1 41 watt pump so I don't what what to tell you..!
It sound like you have a restriction or blockage somewhere along the line from the pump output to the grouphead. My 2001 Rancilio Miss Silvia uses the 41 watt Ulka pump, & the timed measured output through my grouphead into a Pyrex measuring glass is 110ml in 10 seconds (going by memory). I'll check my posts on this to be sure Anything from 90ml upwards is fine.

I'm resizing the pic so it's fits here, so it'll take a few minutes.

tempted to throw in the towel and buy myself a new machine...... however you could be correct on blockage. It was pretty scaled up. Maybe I did not descale it enough. Need to wait till payday to purchase some descaler.

I've seen online pics of these boilers HALF FULL of scale!, & it doesn't take hardly anything to clog up & slow the works down. {:-O


P.S. I've posted some CG links above about the rating for my/the Ulka pump output - water debit.

Maybe you could detach the pumps output line & measure the output for 10 seconds & report back what you get please.

Craig.. one last question.... If I were to buy a descaler product, would DEZCAL be effective?

I've never used or even read anything about DEZCAL, so I can't offer an informed opinion Bryan.
DEZCAL is basically just citric acid, "Dezcal™ is a citric acid based, non-toxic, biodegradable and safe descaler that breaks down lime scale and calcium deposits." from the URNEX website.
It is designed for this purpose, though it's expensive at $6 - $8 for 4 1oz packages! Do you have any citric acid?

That can be had cheaplyfrom wine making & home brewing shops, or in the grocery store, Indian grocery stores as "sour salt".

When I bought my citric acid, I pretty much have a lifetime supply of 10 lbs for $10 years ago. {;-)

as far as citric acid locally, I found this at ACE hardware.. Click Here (www.acehardware.com)
Good enough? What ratio do I add this to water? My reservoir holds about 6 cups of water.

Another brand I found is by BALL, the canning company. I would imagine that they are all the same.... right?

Sorry, I had the computer on hibernate as I was watching the CFL Grey Cup., 100th Grey Cup Championship: Calgary Stampeders vs. Toronto Argonaunts.., 22 to 35.

Yes, good enough. A good starting ratio is 1 - 1˝ Tablespoons to 1 quart/liter.
See Jim Schulman's Insanely Long Water FAQ, (Look down ľ's of the page to: 4.Water Treatment and Preventive Descaling for Espresso Machines) everything you wanted to know about water but were afraid to ask is all here LOL!

Yep, citric acid is citric acid. {;-)
