Horstmann Economy 7 not working

[roblowe]

Hello, my Horstmann E7 isn't working in my apartment. I can here the clock timer ticking and the boost timer is working but no hot water is being expelled. The indicator lights for boost or timed are not lit up. Does anyone have any advice on how to troubleshoot/fix? Please let me know if more information is needed! Thanks.

Check the fuse/mcb for the circuit. Some of these timers had a battery or mechanical back up depending on the age.

Hi Rob, did you get sorted ? If yes, would love to know what you did... Having same issue in my apt, boost working but timing function not heating the water. The clock seems to be working fine & advancing on, but just not heating the water overnight... Thanks!
