I have had my Brewtus III-V (vibration pump) for almost seven years. Its usual behavior upon startup has been to buzz for a few seconds (5-10 seconds) and then start to heat up. The buzzing usually terminates with a very brief uptick in volume before stopping. A typographical representation might look like this: [click on] rrrrrrrrrrrrrrrrRRR [noise stops machine begins to heat up]. Sometimes there would be no buzzing at all upon turning it on and it would begin to heat up right away. This was its normal behavior until recently.
Now, when I turn it on the buzzing frequently goes on for a very long time-up to three or four minutes before resolving in an uptick in volume, like this: [click on] rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrRRR [noise stops machine begins to heat up]. Sometimes it still starts up with no noise and begins to heat up right away. Is something about to fail on the machine? What should I check? Any advice would be appreciated.
