Hi. I have an Ariston LS603 and I think the heating element is dead. Since this dishwasher came with the house we bought, I don't have a manual or know anything about its operation. My questions are: Is Ariston a decent brand of dishwasher? Is the LS603 really old and therefore at the end of it's lifespan? Is this dishwasher worth repairing or should I look to upgrade? Where can I source a manual? Thanks Peter
