6yo Bosch Exxcel Aquastar 6.5L repeatedly showing the E04 error. Seems to get most of the way through a wash cycle before error occurs.
According to advice on this page I checked and cleaned the spray arms, and found nothing blocking any of the holes. I have also checked the drain filter and impeller which is clear. Drain is not kinked and working fine. Turned off for >20m at plug to reset multiple times. When running a test cycle with dishwasher empty I opened to check and noticed that the water is cold even after the detergent drawer has opened, running on an intensive cycle.
According to all the advice the issue is a faulty flow sensor (like this one I think), but I'm concerned that the water is not heating up at all and if something else is the problem. Any ideas or do I need to contact a pro, or just bite the bullet and buy a new one? TIA
