Indesit DI450 dishwasher not heating

[Hombresito5]

Hello, it looks like I have the common control board fault (DI450UKC model). Water not heating (5th LED fashing). I’ve checked the element and thermal switch and they have good continuity and insulation.
I’ve read that the relay can be an issue but the Omron G5LB-1-25 is discontinued. Should I just buy a new board? Could it be anything else? Any simple board checks I can do? I reckon the machine had only done around 60-70 cycles, maybe less. Thanks

Have you checked Farnell, RS or Maplin for an equivalent relay?

Hello, yes I’m fairly sure that I can get a replacement relay. Just not sure if the relay is the actual cause of the machine fault, or if there are any other tests I can do first. A relay at £2 is certainly worth a try before changing the board at £65-75! Thanks
