Thread: Silvia Hot Water Issue (switch fault?)

Hi all, I’ve PID’d my Silvia about 3 months ago based on the guide prepared by Warren S (posted on CSnobs) and have been enjoying my coffee more since. I haven’t used the hot water from the steam wand since (may be once or twice) and when trying to use it this morning, I realised it wasn’t functioning:
- when switching on the ‘hot water switch’’, the pump didn’t run at all & the indicator light on the switch didn’t come on
- there’s no issue with brewing
- also no issue with steaming & no blockage on steam wand
- when switching on both the brew and hot water switches, the indicator light of the hot water switch came on. Pump was running fine
- PID controller is working fine

Opened up the top cover and checked all cables and connections to be in good conditions. 3-way valve works fine during brewing.

Pump is good and it seems the hot water switch is a likely suspect?

Appreciate advice on the above - possible causes and checks.

Many thanks !

ps. Searched on the web but couldn’t find report on a similar fault yet.
