Hello this morning I woke up to a unfortunate situation. My VPP655 PWM single started to make some awful racket inside my pumpres and spread a black powder (most likely Stainless Dust) in my entire loop in a matter of seconds.
I took apart the loop and I when i removed the pump i found it to be packed with stainless dust and a severe scoring on the cup and impeller magnetic area. Rotating by hand i can feel that the impeller scraping.
This pump was bought in January and this is far from my usual experience of having D5 pumps to last more than 5 years.
