Jebao 20,000 variflow 14 month old failed need help .
Hi, I wonder if anyone can help me , I brought the 20,000 pump 14 months ago from an ebay business that no longer exists
my pump no longer works correctly displaying odd wattage (higher wattage ) than it used to, it randomly shuts itself off with er-04 code after a few mins working constantly for no reason but works fine if on lowest power setting, and above setting 80 wattage goes to above 230watts causing the pump to reset and try starting again but fails every time.
I thought my bead filter may be the cause however when I bypassed it using just a k1 micro bio chamber with a max head height of 50cm it still does the same thing.
I haven't taken the pump apart yet to investigate further I was hoping someone here may know the cause .
thank you
mark

I think you best take a look inside. Er04 is usually the impeller’s jammed. I use k1 micro also and it’s amazing how it gets everywhere (usually where you don’t want it).
For a full reset. Make sure you take the control unit off mains for a couple of minutes. Then restart on the lowest setting and work upwards.
Best of luck!
