After years of being frustrated with my dishwasher not cleaning things properly and having to handwash alot of the items after each wash (so annoying!), I have finally worked out what makes it happy:
- lightly rinse items before putting them in, especially mashed potato, dishwashers DO NOT LIKE potato!
- clean the filter at least once every week. Remove it completely and give it a good scrub.
- every now and again, use a dishwasher cleaner, this really makes such a difference! Around £3 from large supermarkets. Just bung it in on it's own and put on a cycle.
Hope that helps! x
