Hello everyone. So now that my machine has been working for almost 3 months without any incident and I am really happy with it I have a problem again since today! The machine has been humming for the last three days! And today water was leaking out. So... Machine taken off power and opened. After the power went out, she kept humming. The humming comes from the back of the pump (this little red thing called E Type Ex5). The noise it makes is an even humming, high frequency. Only when I turn the water off completely does the pump stop humming. Since I don't leave any screw unused I disassembled the pump but couldn't find anything. My first tip is the pump, my second idea is any valve that doesn't close properly and simply supplies the pump with water.
I would be very grateful for ideas and repair tips as always!
