New owners of a Burstner Lyseo (2017) doing all the checks to ensure we are set for our first trip and no water. On the control panel no water pump light either - electrics all good. Taps all good microswitches working. Possible fuse? But how would we know and there is a black switch near the pump (would normally have a lit red light) which also isn’t working. Hope this makes sense. Thank you.
