If you turn off the water supply and disconnect the water hose from the VII the pressure gauge should show zero. If it does not it probably is the gauge.

Re: Crema

1) How long are your shot pulls?
2) Typically this is caused by using old beans. The crema is caused by frothing as the beans release C02 when the pressure is removed; i.e. as they exit the PF. However, unless the beans are fresh, the C02 has probably already out gassed.

Re: Flowmeter alarm and no solenoid click. HELP

There was another person on the forum that had a similar problem with their group solenoid. I gave him instructions on removing the power connector from the solenoid and checking for 110V AC on the connector leads while it was removed and one of the coffee buttons pressed. However, as soon as he rem...

Looks good though I think they should remove the words "slow roasted" from the bag. This is usually not considered a good thing in coffee roasting.

If you're still just trying to track down that leak, you only need to be removing a couple of fittings from the top of the boiler. Putting them back only requires Teflon tape wrapped around the threads. You should only need to remove the top of the boiler if you plan to descale. If you are planning ...

Re: Mini won't pump water...

Here is my preferred method to descale - assuming you don't want to do the option where you remove the boilers for descaling. 1) Remove a fitting from the top of each boiler, inserting a thin vinyl tube, and siphoning the water out of each boiler. Best option for the group boiler is the threaded plu...

There are 3 ways that water can escape the steam boiler. 1) Loose hose or fitting 2) Vacuum Breaker Valve 3) Pressure Release Valve. You can probably rule out #1 since that issue would likely leak continually. The VBV, assuming it is working correctly, can only leak before the water comes to a boil....

Re: Rebuild... Vivaldi S1. Safety valve blowing off.

The pump doesn't provide the entire set pressure. It actually provides the boost needed to get from incoming line pressure up to the set pressure. So if you have the pressure set to 9bar and your house pressure is 5 bar, then the pump actually produces 4 bar on top of the 5 bar to get you up to 9 ba...

Re: Rebuild... Vivaldi S1. Safety valve blowing off.

Give it a try. You may find that both boilers work fine with the temp sensors swapped. If the swapped one fails in the group boiler the effect will be that the expansion valve repeatedly opens up and dumps hot water into your drip tray, but it won't damage the boiler. Of course, should that happen, ...

1) It's just a fluke that the steam boiler problem happened right after you adjusted the expansion valve since the expansion valve is an adjustment for the group boiler. There is no interaction between the two. 2) What you referred to as the contact thermostat LaSpaziale calls the thermal breaker. I...

There's Teflon collar around the water level rod. It compresses / shrinks with age and then the water pressure can slowly push the rod up. And your picture did make it look higher than it should have been. It doesn't take much.

The VBV sputtering and then pressure jumping up when it closes is normal.
