MInima

Eyedee

I bought the black Minima from Dave Kidd in February after letting my previous one go for a song.

It seems the Minima curse is following me as I’m getting long (15 to 18 seconds) running time on the pump which has been a constant from the onset but today it was even longer and now I’ve a jug of very watery milk as the steam is filled with water.

If I purge the wand I can actually see the water mixed in with the steam and the pump runs much more often to keep filling the boiler.

The plan is to contact ACS and see if there is an easy sokution.

Eyedee - I don’t have a minima. But from reading some of the threads and posts here - the fill probe is often talked about - whether it’s due to boiler overfilling, or faulty, or whether it’s not ground properly.

fill probe on the steam boiler perhaps?

Is there a fill solenoid? It is a while since i had my Minima. If so, it sounds as if water destined for the brew boiler is bleeding into the steam boiler whilst brewing leading to a weak flow and overfilling steam boiler. Try cleaning the valve seat in the solenoid.

A replacement probe ordered.

If the replacement probe doesn’t solve it check where the thin black wire from the Gicar box is earthed to and whether the earth is secure and not loose.

Having had this issue, check the earth wire

When the fault arose the first thing I checked was the earth wire.

Eyedee I hope it is something simple like the probe, although I doubt changing it will solve the problem unless the existing one is scaled…often though the act of removing the probe as you slide it out, sloughs off any scale…so it’s hard to tell.

If it doesn’t and there’s no loose wires, it might well sadly be Gicar Box time. As it’s a box with a lot of functions built in, including the PID, it’s not going to be super cheap.

Thanks for the info, I’m under guarantee until Oct so lets hope the faults show before then.
