Biasi combi condensing boiler ignition keeps swithing OFF when

Customer Question

Biasi combi condensing boiler ignition keeps swithing OFF when the heating is turned on s after 5mins to 3 hrs. sometimes when we turn on the hot water tap the ignition goes off sometimes not. I have noticed that it sometimes goes to full temp (I can hear it trying) but more often than not it doesn't get above 15 degrees, then switches off. The heating pack with rads was bought and installed about 8.f years ago, with a service every year. Had no problems until we set the heating a a very low level 24hr a day. ran perfectly days and then started shuting down. Noticed the condensing pipe u bend is full of water even when boiler is turned of a mains.
Can anyone help, as our long standing plumber will not touch a biasi and wants us to replace.
