Hi,

Last night my Brewtus made this weird sound like a turbine winding down (abeit softly). After that the temperature dropped to about 89 (normally 96) and water would be flowing from this pipe (see photo). Water continued to flow in a slow stream till about 95 C when the water turns to slow, from that point the flow is mainly steam and splatter (of water). I assume it is some or other seal but I need the name of whatever that pipe is, and if possible, the name of that seal (or problem) so that I can order and replace it.

My guess is that that is the outlet from your relief valve (OPV). Confirm by looking at the back side of it and following the hose.  Quite possibly, the relief valve is just stuck open by some calcium build up or such. It can be dismantled, cleaned and inspected before making the decision to reassemble or replace.

lol, this happened to me. I have the plumbable/reservoir model but I don't plumb so I just replaced the line leading into the drip tray with one leading back to the reservoir as a return. In the non-plumbable models this is how its set up.

You can open up the back of the machine and just run a 1/4in teflon tube from the splitter coming off the OPV valve (see photo), back to the reservoir. Turn the machine off prior to doing this, and be prepared for water to come out from in the lines. I left the old 6 inches of tubing from the original set up in place.


If your machine is plumbed do not run a line into your reservoir, this is designed to relieve the pressure that may exist in your plumbing. presumably your drip tray would also be plumbed so it would never fill.

OK, I have been away on a ocean cruise and has been quite disappointed at the espresso they tried serving up ... Quite amazing the issues I can see with a bit of hands-on experience. Anyway, my problem still not fixed and appears bigger than I thought initially. Video at Youtube.

This thing is now not working at all, at least I can still steam milk for hot chocolate for the kids ...

Does the water flow from the group head without a porta filter installed?

The pump turns on but it seems that the water valve is not opening to the brew chamber. A thread at coffeesnobs has the following GH drawing:

Is your machine fully heated there? The pressures seem way out of wack. I have no idea what could be causing that, perhaps its a bad pump?

There is actually no water coming through the top at all currently. Either there is some really screwed up valve or seal or the pump left this earth. Will keep posted.
