Hi, Have an ideal isar HE30 boiler which has stopped working. Electricity going to boiler but no display on the front. After reading the forums bought a new pcb, have connected it but the boiler still does not work. Any help at all would be appreciated as I have had no hot water for three days. Thanks

Are you sure you have conected it properly? There are two connectors (one being the L,N &E) that will fit in each others slots.

The usual fault is water leaks from AAV onto display PCB and its rear connector.

Sometimes the main PCB fails because the power supplies are not protected. But not always!

Whatever is dont the essential is to cure any water leaks before the replacement parts are spoilt again!
