In the last chapter the machine was opened up for servicing. Now the Brew group will be removed for restoration. The few screws required for removal will continue along the same number system as before, also hose connection 18 will be moved to the front door as it seem a more logical location for it.
The brew group comes would with relative ease, and its nasty, vacuumed first before I even work with it. Also a visual inspection is important before work starts in the attempt to find a fault. after which, disassembly begins; an order of operations is followed. During disassembly, the first failure is discovered, the o-ring on the piston. The plunger o-ring also shows failure.
Completely disassembled, A tub of water and cleaner is set up for the parts to soak and be brushed then rinsed one by one and set off to dry in a separate area. Each part is also inspected for damage or wear. The metal element was specially cleaned, many holes were blocked, it took a lot of time and care to free it up.
I will be using the Brew group rebuild kit for the next task, all new Orings are added during assembly, the supplied lubricant is used where specified.
