Hi all, Just found this group after having my Australian spec Brewtus IV (Vibe pump) for about a year now. I've had some ideas for mods that haven't been discussed before, which might be for a good reason! I'm a bit perplexed that the general consensus is the steam production is quite poor compared to other dual boiler machines. Especially since the Australian spec Brewtus/Minore has 2000W heating elements compared to around 1300/1400 on competing machines. Admittedly the steam boiler is on the smaller side at 1.5L but this should only impact initial steam pressure. I haven't had the opportunity to test this out in person however.
Anyway that aside: 1. I've been thinking of installing a normally open relay on the steam boiler auto fill probe, such that when the brew lever is engaged (micro switch powers pump), the relay will energise and short the water level sensor wires. This would ensure the steam boiler does not refill mid shot. This seems like it would be quite a simple mod, but I can't seem to find anyone who has done it before. 2. Another idea is to install additional plumbing and a solenoid valve such that the steam boiler heat exchanger could be mechanically bypassed. This would allow higher steam boiler pressures without overheating the brew boiler. Or alternatively leave out the relay, and install a restrictor such that water splits roughly equally between the heat exchanger and non-heat exchanger paths to the brew boiler. I'm sure there are a number of things I am not considering, so any input would be much appreciated.
