No noise of the pump even no buzz? Pump getting hot? Are you sure that the water flow from the tank to pump is OK? Remove the tube and suck water to test that there is no jam. Leaking water can deamage the pump as well as other electric elements. Make sure to fix it. Be aware of 220 Volt electric power! I assume the pump ist broken because of water dripping in. Not sure about the ceramik ventil. You also have to check about water demage as well.
