A Miele washing machine door lock goes under Dave Jones's knife
EEVblog 1777 reverse engineers the W1's failed interlock to find the broken part, while a three-week-old op-amp exam question draws the most viewers each day.
Why this story? The channel's weekly summary: what went up this week, what is drawing views now, and where the channel stands among similar channels.
EEVblog 1777 - Miele W1 Door Interlock Teardown
Twenty-one days after it went up, a single exam question is still the busiest thing on EEVblog. "EEVblog 1771 - A Tricky OpAmp Exam Question" has Dave Jones working through a problem that asks students to use frequency and ignore it at the same time, then turning it into a bonus lesson on op-amp biasing, ripple filters and why it pays to think about what sort of exam you are sitting before you answer. It has passed 300,000 views and draws more each day than anything else on the channel.
The one new upload was more domestic. "EEVblog 1777 - Miele W1 Door Interlock Teardown" takes apart the failed door lock from a Miele washing machine to work out how it is meant to work and what gave up. It opened with about 36,000 views on its first day, and the comment section turned into a repair bench. Several viewers sketch out what each contact and the solenoid do, others suggest ordering two replacement parts so one can be opened and compared, and a few wonder whether the missing broken piece is lying somewhere on the laundry floor. One popular theory credits a bimetallic spring with the delay before a front loader lets you open the door.
In between sits "EEVblog 1776 - Get paid $175/hr to eliminate your own PCB Design job!", Dave's look at an offer to train AI on Altium Designer, the very software a PCB designer might be replaced by. Nine days old, it is running nearly level with the op-amp video.
The channel as a whole is moving slower than usual, though among the science channels closest in size it gained the second most views of the week, behind only Reactions, which is having a very big week. Isaac Arthur sits just behind.

What viewers say
Someone in Germany had a lot of fun and time to design this just to confuse poor old Davo down under.
