Hi, thanks in advance for all replies. I own a Belling Dishwasher, model IDW604. Its showing an error code of E3, which in the manual states the heating element or thermostat. Are either of these a costly repair? I'm thinking of doing the repair myself, are there any tips on these type of repairs anyone can offer. Would correcting this fault code be quite advanced or a simple job. Im quite competent but don't want to end up breaking the entire machine. Any advice is great fully received. Thanks.
