Hydramaster 4.7 CDS Help

[Diego-]

Hello,
I recently bought an older Hydramster 4.7 CDS. Everything works great except it doesn't pump in water from the fresh water tank. and in these cold days I need to use the water on board. When I turn the machine on and turn the switch on for the fresh water pump the light doesn't even turn on (at Panel). I also can't hear the pump working. The pump is directly wired to the inside of the panel. How can I distinguish if this is a bad pump or an electrical issue?

Continuity and power check from hot on panel switch to hot on pump if you have both pumps bad. If your pumps one with a microswitch vs an internal bypass check the mucriswitch 1st

When you say older, how old. When you look in the water box does it have a float like a toilet bowl, or does it have two switches one above the other. If you have the two switches the pump is wired to the switches through a relay. when both switches are down they turn on the pump and when both are up the pump cuts off. It could be the relay, the switches.
