#pump

Hello, Recently, my jebao dcp-5000 pump have started working very strangely. It works normally up to 40% power. When I set it above 40%, I can see on the screen that power increases but after reaching this 40% power level, it drops back to zero and this reapeats itself endlessly. No error code...
