Hot water and heating working but only at low demand?
Im just wondering can you help my boiler is 21months old and Im being told the warranty is invalid because worcester didn't carry out the first service, Anyway the boiler will work on very low demand but if it needs to kick up for say a bath full of hot water after 5mins it goes to lock out I can reset and go through the whole process again. Hope you can help.
