And, I did not forget this request. Flow restrictor should be on next order to arrive in December. As for the solid state relay, they are investigating a new relay, but they do not know which type nor the time line of this improvement.
The next batch of machines will have an improvement or two, but they are not saying. Thus, the price increase from them.

Espresso: La Nuova Era Cuadra II,... Grinder: Rancilio Rocky w/ Doser
Posted Fri Nov 8, 2013, 7:11am Subject: Re: La Nuova Era Cuadra Owners Thread
Hey experienced Cuadra owners, Just experienced a similar problem to a previous poster, but with no clear answer. Recently descaled my machine and recharged the water softener, and for a week now have been experiencing a problem where the machine heats properly but the pump stalls when pulling a shot. It will operate as normal when just pulling water through the group head, but as soon as it meets any resistance (i.e. espresso grinds) the pump all but stops. It then cycles through barely kicking on and off as the lever remains pulled. The espresso barely comes out. I have tried a courser grind to reduce resistance, but this is a new problem for me and this machine. The latest trial was removing the water softener completely, but to no avail; same problem. It shouldn't stall out when meeting minimal resistance, and never has before. Any ideas on what to try or what may need replaced?

An espresso machine's gicleurs or restrictors can get get clogged from water evaporating inside in as little as 2 weeks - mostly depends upon the hardness of the water. Therefore it is best to descale before this inactivity and refill with soft water only. Do NOT leave descaling solution inside as it can start to eat the metal (ie copper) or gaskets on some machines. After descaling but before the period of inactivity for the Cuadra, remove the hoses from the reservoir (remains full), run the grouphead dry of water by running the pump for about 20 seconds. Leave lever up. Cool machine down and leave steam and hot water valves in full open to allow boiler water to evaporate. Empty reservoir. Allow water softener to air dry after removal - do not leave it in the reservoir as the remaining water may allow mold to build up.
If the machine is going to be transported or shipped, you can do the same above, EXCEPT before the machine cools down to leave the valves open, you would leave the machine to full heat, then power the machine off, and empty the boiler through the hot water valve only (steam valve stays closed). Not all the water will come out. Allow machine to cool and open steam valve. It is better to keep the valves open and lever up especially in cold weather to avoid any remaining water to freeze and cause damage. It is less important in warmer climates.
