I bought a 10ma RCD adaptor last week after my 30ma RCD broke. At my location, I've a circuit breaker in place and I use the Rcd adaptor to test machines in case it trips the whole place. The machine runs on 230V and had a broken power light. The machine could heat up

Be wary of so-called turbine tips. Once the steam leaves the hole, it goes in a straight line. No matter how the holes are arranged, steam simply shoots in a straight line away from the tip. Good swirling comes from the barista's technique and the type of pitcher. Motta pitchers are awesome. The nar...

The whistle is the OPV. I get it with the Strega if there's a lot of resistance pressure with the vibe pump running on an extraction. The vibe pump is rated for 15bar. The OPV is probably adjusted to a pressure over 9bar. I've read if you adjust the pressure down to 9bar the whistling should

Sounds crazy, but I noticed the OFF/ON brew button actually has a third position which activates the 3-way solenoid only. That is: Button out = off Button partially pressed = solenoid valve energized (water flow open to group) Button pressed further = solenoid and pump are energized Button fully cli...

Hello to Everyone. I am based in London, UK. I am Considering to upgrade my Bambino Plus which I modded with a IMS shower screen, bottomless portafilter and IMS competition 14g basket. Having started my espresso journey 1 year ago I am quite happy with what I have at the moment but always thinking a...

I'm replacing the pump on my Bezzera BZ10. The parts list calls for an ULKA EX5, so that's what I ordered. The vendor sent me an OLAB instead. It looks the same and has the same fittings, but I don't know if I should return it because it's not what I ordered or whether it

I'm working on my Bezzera BZ10. I took apart the 3-way valve assembly, including the OPV. I'm surprised that there's no gasket along the path to the brew group. There's a small o-ring on the one-way valve/spring, but nothing on the overall ...

Just to answer your question, it's a Bezzera BZ10. BTW, the problem was the silicone o-ring lubricant I used. I applied too much of it. Over time, the stuff gets sticky and that's why my portafilter stuck to it

When I press the brew button, the pump makes a muted vibrating noise and water trickles back into the reservoir. No water flows out of the brew group or into the drip tray (the output of the 3-way valve). I traced the path of the water flowing back into the reservoir. It's coming from a tube just
