Ariston LSE615 or Indesit AF350X part location

Hi,

Bit of trouble pinning this dishwasher model down to a UK equivalent as it’s Spanish, but did find Indesit AF350 looks identical except it has an extra LED light for rinse aid being low. It’s hard as Ariston, Indesit and Hotpoint seem to be the same company. The machine looks identical to this: http://imagebank.indesitcompany.co.uk/brochures_online/pdf/Ariston/Dishwashers/AF350X_034628gb.pdf

Anyway, the machine gets stuck on the first cycle when put on a 55 degree wash, and only gets to the 2nd stage if a pre-wash is selected, which presumably uses cold water. Found when opening the door after it’d been running for ages and not advancing the program, that the water wasn’t hot, so reasoned it was waiting for a sensor to say the water was up to temperature before advancing its program to the next stage.

So next step is to check the heating element for open-circuit, but my dad can’t seem to find it and since I’ve never taken a dishwasher to pieces, I can’t help over the phone. Could anyone advise where it’d be located please?

Thanks!
