comment Plug-In Power Monitor causing washing machine drum to become electrified?
I also discovered a disturbing fact: the polarity does not even need to be flipped for the chassis and drum to become energized - I tested inserting a plug adapter with no ground connection between the washing machine plug and the power outlet. (so it just has live and neutral connections). The same effect occurred: the drum became energized and putting my proximity voltage detector within 40cm of the unit resulted in it beeping (it usually needs to be within 1cm to detect anything.)

I don't understand how I can get shocks from the drum and chassis and they can set my proximity voltage alarm off, but no readings come through the multimeter. Is it because I can only rest the probes on the metal drum and the resistance is too high in my multimeter and the current is happier to flow through the chassis?

Hi. It's been 1 year since your last comments, but I wanted to provide an update and ask additional questions. Per your advice, I purchased and trained up on how to use a multimeter in order to diagnose this issue. My results: From ground on plug to drum is infinite to 120,000 ohms resistance (changes when it moves). To other parts of the metal chassis it shows 83 ohms resistance. The live and neutral prongs on the plug show infinite resistance to each other. All other readings are infinite/blank, including voltage and current readings from drum and chassis while they are energized. cont...

Either way, if polarity is flipped or grounding is dysfunctional - this would require that either a neutral or active wire inside the washing machine was inappropriately touching the chassis, right? Is that correct?

comment Plug-In Power Monitor causing washing machine drum to become electrified?
Well, the UK and AU plugs form a "T" shape. But in the UK it's upside down. They both have neutral on the right side. But the cheap adapters keep the "T" facing up, so the UK is upside down. On my more expensive adapter the AU and UK are both facing the right way. So, you would think that the neutral would stay on the right... but maybe one of the adapters is attempting to correct the fact that the "T" is facing the wrong way... by flipping the wires' positions... but then the UK to AU adapter is not...

Thanks for that. I confirmed with the manufacturer that they do not bond the neutral wire to chassis or drum.

Another question: would any of this suggest that the grounding cable in my building isn't functioning correctly?

No. But it does appear to flip the polarity.

comment Plug-In Power Monitor causing washing machine drum to become electrified?
I found that the power monitor is not the culprit for the polarity switch. All I need to switch the polarity is a AU to UK adapter then a UK to AU adapter plugged together. Because the UK plugs are "upside down" with the two pins on the bottom, the way the cheap adapters are designed it's actually flipping the wires. See: images02.olx.co.za/ui/19/10/38/… If it wasn't for your excellent response I wouldn't have been able to convince the manufacturer to send someone to investigate.

comment Plug-In Power Monitor causing washing machine drum to become electrified?
I had some questions: Is there any way to test if they Neutral wire is touching the drum when the machine is just plugged straight into the wall and my voltage detector doesn't detect anything? 4 years ago my washing machine was attached to a power point that burned and melted. I never found out the cause. Here is a picture of the washing machine plug. lh3.googleusercontent.com/-E3h99PbZ23c/UtpI6Z-s0gI/AAAAAAAJMoY/… Could this be causing the wires to cross in the plug somehow?
