Hi All,
wanting to pick your collective brains on what the problem might be.
As some of you know, I have a cart I take around to some local markets to knock out a few coffees. The machine I got with the cart is an old 2 group Milano, which Im told is a rebranded wega.
recently Ive been having random cutouts on the pump during a shot. The pump sound stops, the coffee slows to a trickle and the pressure isnt released through the solenoid. It doesnt work for a few minutes afterwards. Meanwhile, we stand nervously grinning at customers who frequently have a frown on their face. It used to happen when we were pumping out the coffees, but now cant stand up to more than a few in a row; except when a technician is troubleshooting of course.
I had the pump replaced by a technician last week. I had asked for both the pump and motor to be replaced as I didnt suspect the pump to be the problem, but he thought otherwise.
The question is; should I spring for a new motor? could it simply be the capacitor? or is it likely to be some of the electronics. The problem occurs when using the manual switch and the volumentrics. It also happens on both generator and mains power. The cart itself also has a small caravan pump to simulate mains pressure and that continues working quite happily during these tantrum episodes.
Thanks everyone,
