For priming issue, press the start button at least 2 more times.

Não sabia nem o que é, mas agora não tenho ideia de como isto se chama em PTB.

Water Priming: If you've turned your water pump off over the winter months, chances are that it has run out of pressure. To get it working again, your water pump will need to be primed. This means that water will need to be flushed back into the pump and forced through - this creates the pressure it needs to begin pumping again.

Agradeço toda ajuda!
