I have a 220V Isomac Rituale that I bought while in living in England. I moved to the US three years ago and have been using the Isomac daily (with a 110V to 220V step up transformer).

I recently made a domestic move within the US and now my Isomac is dead. I initially thought it might be the pump (which runs a little faster in 60Hz land than 50Hz land) so had a 220V vibratory pump sent from Europe. Unfortunately that hasn't fixed the issue. The red light comes on to indicate the boiler has power, but no activity from the pump - either to fill the boiler, or when I activate the lever to 'pull a shot'.

I've reseated all connectors and still no joy. Disconnecting the autofill probe makes no difference either.

I can't understand what might have happened in a move. The worst I can imagine is that something got 'bumped' in the moving. I'm really hoping it's not the Giemme control box - both because it's expensive and getting a 220V board in the US is difficult and it may not even be the problem.

Is there something obvious I'm overlooking?

Thanks

Maybe this will help although I realize yours is not a heat issue.

ECM Giotto Premium pump stops after heating up

You can always make up some temporary lines with inexpensive lamp cord & crimp-on connections and test the pump directly (with the machine off & unplugged) after removing the existing connections.

Thanks for the input. Unfortunately my pump does not have a Klixon. I know the pump is good because it's brand new which is why I'm questioning the control box.

Well, if the boiler has little or no water in it, the very first thing I would do is disconnect one of the leads to the heating element so as you don't double your trouble. Here's an electrical diagram for a Millenium which may/may not be similar - I realize the different voltages.



European machines may have different safety features for low boiler water level so posting a pic of your machine's internals may help.

Have you tested it? Knowing the pump is new, and knowing the pump is good are two different things.
