On the leak front I've fabricated a better drain arrangement.
New drain arrangement with 90 elbow to avoid crimping drain line. |
I took the 3 way valve off and disassembled it. Here's what it looks like connected with a good shot of the color codes.

Three way valve removed and partially disassembled. |
Disassembled base and nucleus. |
There's a good description of 3 way valves here. Based on this the valve is a 3 way valve with a flange body 110v coil and ruby valve nucleus.
Karma Dave said he'd order one.
Issues:
- Should I drain the boiler? Shoud I descale? - DEFERRED
- Parts - OPEN
- Karma is ordering
- Steam wand
- Group head O ring
- 2 shot basket
- 2 shot spout
- back flush basket
- Drips from three-way valve - need to replace valve
- Pressure gauge - Seems OK.
- Pressurestat - Seems OK
CURRENT PARTS LIST:
- Steam wand - Looks like Espresso Parts has an after market wand at a reasonable price (>$40). Karma will order.
- Citric acid: I'm going to defer this for the moment.
- Amazon offers "Spicy World Citric Acid, 5-Pound"
- Are 1 or 2 tablespoons of citric acid per liter the correct concentration?
- Portafilter - Espresso parts is a source or Dave may be able to help
- Double basket
- Double portafilter spout
- Backflush disk
- Group head gasket - Espresso Parts has part. It is described as RANCILIO GROUP HEAD PORTAFILTER GASKET - 74 X 57 X 8.2MM. There is an aftermarket part as well described as "An economical alternative to the O.E.M. gasket. 73.5 x 57 x 8mm."
- Three-way Lucifer - Parker Solenoid valve 110V 50/60Hz 9W Part number 491514P3 D400P3.
CURRENT TODO LIST:
- Buy/acquire needed parts
- Replace three way valve
- Flush machine to resolve taste
- Sort out drain hose issue.
