My WP25 stopped working too, and it was very clean. It happen once before and then all of a sudden it started again, but this last time it wouldn't start again and I just gave up on it. Some time you get what you pay for, it seems to be the case with Jebao products.
Didn't spend much $$ on the WP40 which has great flow, but it seems to have broke down about a year later. The power supply works and the impeller looks clean, just won't spin. Anyone have a similar problem when using this wave maker?
I've had my Vortech's much longer than that.
two of mine die....hahaha!
