On board water tank fault
Hoping someone can help. I have a Swift conqueror 480 2009. It has onboard water tank which is filled up from the external aquaroll. Once the onboard tank is full it shuts off the external pump. When the onboard tank drops to 1/2 full the external pump should
switch back on and fill the onboard tank again. The problem I have is that the external pump will not switch on unless I turn off the control panel and then turn it back on again. Before the onboard tank gets to 1/2 the control panel beeps and displays the
message "check external water supply". The external tank is full and the aquaroll pump works if I switch off the control panel and then switch it back on again so the external pump appears to be fine.
