Software doesn’t happen to cover industrial dishwashers too, Seamy? And where’d you trip over the interface?
If it was an electrical part for a car, there’s no way the dealer would take it back if it left the premises…
Last I heard it was a pound a plug round here (mostly schools). Bunch of butchers tho, just chop the plug off anything that fails…
If you press the release button for the flap does it spring up smartly? If not, it sure sounds like time for a new dispenser…
macmini, not so sure about that. Let me get back to you- my father had an item delivered from Argos recently, and both the uplift from the central warehouse and the local delivery (we’re in N.I.) were carried out by subcons. He actually got a card through the door from the mainland-based firm that do most of the work for Argos (I believe); hopefully he’s still got it…
… one phone call later.

Wow rather than flutter, in audio parlance…Interesting indeed. Clever stuff for sure- I’m continually amazed by the amount of logic built into these white boxes…
For years we’ve been using various designs of accelerometers and deflection sensors to detect OOB in lab centrifuges. These are either direct drive motors, or sometimes geared up above motor speed, and are running at up to 30k rpms- little chance to measure rotational speed there…
Basic stuff just trips a microswitch on the chassis if motor mount deflection is excessive, others have used a pendulum and bob-weight to make a contact, modern stuff tends to use a piezo vibration sensor.
