Hi guys. I need some help to fine tuning my Mininova.
After purchasing a second hand Mininova that had been in an office environment for a few years then in long term storage t required a little TLC. After some investigationing, advise from this forum, a few parts and some effort, the machine is making good coffee. The problem is that I seemed to be able to make a better coffee with my sunbeam em6910. I think that if I tweak this right I should be fine.
This is a rotary pump unit that was set for mains pressure but at the moment i have it drawing from a container. I will get it plumbed in once I can convince the wife this much bigger machine actually has earned its position in place of the smaller EM6910
The sunbeam is able to run a finer grind of coffee without choking and froth milk much better.
I have fitted a pressure gauge out of an old em6910 to the t-fitting off the outlet of the pump and have increased the pump pressure slightly.
It now produces coffee through a finer grind then when I first got it running (not as fine as the em6910) Now it seems that the 2nd opv leaks quite a bit. I have tightened the opv completely but still leaks a lot under pressure. (Can you get new internal components for these opv's or do i just need to buy a new one?)
With regards to steam. I have tried a method explained on a forum about using full steam pressure for a few seconds then reducing until it heats up. I find this tip spits too much milk all over the place and makes too many large bubbles. I see that some people have replaced the 5 hole steam wand with a 2 hole tip. Any other tips.
Sorry for the long post but I thought I should offer all the info upfront to reduce too much backwards and forwards [emoji4] thanks guys
