Please help! I have a Nest Learning Thermostat. I have hot water on a schedule. About once a week, the hot water fails to come on. Boosting works fine. You have to go to the thermostat and click into the water icon (at which point it goes back to the scheduled settings). Hot water schedule is enabled on the thermostat. Everything else seems to be fine. It is just this random 'once a week' failure to fire up the hot water that is doing my nut in.
Do any of you clever people have any ideas?
