Ideal Icos Problem

[AllanWhitt]

Hi,

Can anybody advise me. I have an Ideal Icos Condensing Boiler, Central Heating if fine but when running hot water the boiler locks out after a while and LE comes up on the error code the boiler runs ok again after pressing reset but then locks out again after a short time, this only happens when heating water could it be the PCB I have heard they are pretty terrible on this model? If it is the PCB is a simple like for like exchange.

Cheers Al
