Ok...so I have foolishly left my Truma Ultraflow Water Pump Assembly out of the Aqua roll and left the pump switch on! Upon arrival on the next morning, the pump switch light was off and the fuse had blown. I have since replaced the fuse and the light on the switch is on, but the pump no longer works. At the same time the Whale blown air heater has stopped working! The fan works, but none of the heating settings work. I have checked all the fuses to no avail and completed a hard reset. Please can you advise how to resolve both issues?
