> When do I need to clean the dishwasher filter?

Dishwashers have filters??!?

[globular-toast]

They do in Europe. They have water softeners too that you have to fill with salt. Don't believe it's the case around the world.

Many have removable filters that you're supposed to clean periodically. If there's nothing obviously removable in yours then it might have a "self-cleaning" system that would be harder to take out and clean yourself.

Wait until I tell you about your water heater's sacrificial anode. NOBODY replaces those.

I got an electric one so I never need to remember to replace mine!
