Ultrasonic cleaner went phut!

Went into the workshop the other day and the power was off. After half an hour of cursing and swearing the fault turned out to be that my ultrasonic cleaner had leaked water through the stainless steel tank which banjaxed the circuit board.

The main RCD detected this, hence the power cut.

I was surprised to find a sizeable (1mm) hole eaten through the stainless tank. I suppose stainless does not mean stainless in all cases.

The machine was this generic type: http://image.made-in-china.com/4f0j00sMSapCEWYlbQ/Digital-Ultrasonic-Ultrasonic-Cleaner-2-5L-CE-Certificate.jpg

​It lasted 3 years and was actually very effective.

Ahhhh Stainless means just that it stains less than carbon steel it does not mean it is rustproof and/or it will not rust.

But the thing had its own heating element to take it to 80 degC.

​I think I was unlucky with a ferrous inclusion in the water tank.

Ferrous inclusions are common in shops where separation from other work isn't maintained, most commonly flying grit / carbon steel frags from grinders.
