Hi all
Moved into new house on Friday; system initially seemed to work ok, but then today there's suddenly no hot water. Setup (pictured):
Vaillant ecotec plus 630 boiler
Honeywell ST6400 heating programmer
Ariston water storage cylinder
Water runs but isn't hot (isn't totally cold either, but far from even lukewarm). Display occasionally reads S.7 (i.e. 'pump overrun'). The rest of the time it reads S.31 (I.e. 'summer mode'). The boiler may have been switched off and we may have been using the cylinder contents over the past two days?
Any help much appreciated!
