A pan that is not induction cookware. A cooling fan running on after the oven is off, exactly as it should. A refrigerator asking for its filter. CL on a display, which is a request to clean the coils. Ice that smells of the bin rather than the machine. Surface rust the manufacturer itself says to expect on this coastline. A dishwasher whose disposal plug was never knocked out. A steam oven asking to be descaled.
Every one of those has a page here that says so plainly, before you have paid anybody to come out and tell you. On a site whose purpose is to get the phone to ring, that is a deliberate cost, and it is the right one.
