My cousins boiler so not earning much off this.
DHW runs perfect, fires boiler and stays on until you close the tap.
CH fires up, runs about 5 seconds drops flame and goes flame failure, last week I changed the CH sensor as it was late evening and I had a spare new one on the van. Checked all leads back to board for continuity all seem ok, reseated the leads onto pcb boiler fired up was running fine when I left, fault now returned, am thinking PCB but anything else I can check before I buy one ??? TIA.
Non condensing BTW
