Recently my V2 has started making a 60 cycle hum (US model) when pulling shots. Sometimes very loud, sometimes quieter. If I flip the shot lever up down up, it will often stop. It never happens if the HX button is not enabled. Time for descaling? Is there some junk (lime [yeh, it’s pretty clean water, but not DI etc]) caught in the valve? Would a nice citric acid bath help? Or does the solenoid need replacing? It seems to be part of the whole big valve assembly so this might be tricky. Any advice appreciated. Thanks

You don’t need HX on for domestic use, it’s there to increase capacity for commercial use.

There will be something in the solenoid preventing it seating properly, so they buzz. Open solenoid and clean.

Thanks Dave…I’ll rip it apart and look.
