My old boss in Cincinnati told me to never trust a washing machine's error code without checking the drain pump first.
He said that about 80% of the time, a 'sud' or 'door lock' fault on a Whirlpool front loader is really just a clogged pump. I argued for years that it was bad logic boards until I got a call for a Kenmore Elite with an F21 code. Sure enough, a single sock was wrapped around the impeller. How many of you still follow that 'check the simple stuff first' rule your mentor taught you?

Actually, I don't think it's bad design or a trick to sell parts. The error code just points to a system that failed, and the drain pump is part of that system. The real trick is knowing which part of the chain usually breaks first, right?

Remember how that rule applies to way more than just washing machines. I've seen techs replace entire control boards in fancy ovens only to find a single bad wire connection from the door switch. Same with fridge ice makers, people swap the whole unit when the problem is just a stuck arm. Your boss was right, but the real lesson is that modern appliances hide their simple fixes behind complex error codes.

That part about error codes hiding simple fixes is so true. Do you think manufacturers do this on purpose to sell more parts, or is it just bad design? I've had a dishwasher throw a sensor error when it was just a piece of food stuck in the drain.
