Re: Error message on Hotpoint Aquarius DWF50 dishwasher
4+6 points to a heater related fault. Quite common on these Indesit dishwashers. could be heater, stat, controls etc. The heater itself is very prone to failure.
Element itself is around £30.00 + vat, not over expensive, very awkward retaining clips, a bit of a fiddle. Best to get the heater and associated wiring and components checked out electrically. Should be worth repairing, also remember that you do have a five year parts warranty. At a guess I would suspect most independent repairers would be able to do this job for less than the manufacturers £90.00 labour charge.
Please remove the mains plug if you intend to proceed yourself.
