hi, many thnks for your reponse. it is an eco tec plus 824. i was getting a red flashing on the wireless thermostat. this has now stopped and the radiator icon has stopped flashig.
as soon as the new insurance starts i will ring for a check. can't believe this has happened in this window...
vaillant eco tec pro has flashing radiator icon.
i get an anticycling message. checked the d and it is set at 0. hot water in taps but radiators not giving out a lot of heat. 9 radiators. i am inbetween two homecare plans,new one starts 17th feb.
should i wait till then to call in engineer
