2013 AI - where exactly is the fuse to change it?

I hear no sound when flipping on the pump. I have been reading different potential issues. I think there may be hair, or it got blown while I tried to empty the tank. >> where exactly is the fuse to change it?

Fuse location is down below the rear lounge in the flip down fuse and breaker panel. If the fuse is blown, there should be a red light next to the blown fuse. Should be a 20 amp fuse.

Macerator pump, blown fuses remedy.

This is the correct diagnosis for the macerator pump fuse blowing. Consider that a simple remedy may be to install a relay in the circuit from the switch. That way you won't blow the fuse (from overload) when the pump starts grinding and pumping the contents of your blackwater tank.

Replace the original fast-blow 20a fuse with a slow-blow 20a fuse. If you don't instantly hear the macerator start up, get your finger off the switch. The slow-blow fuse gives you a second or two to react.

I have never had trouble with the slow-blow fuse in two Interstates over time.

I’m trying to find the 20amp Slo Blo fuses on the net and am not having any luck. I’ve found the Large Maxi ones but can’t find the ATC size. Can you tell me where you got yours?
Thanks

I bought the slow-blow fuses for my 2014 AI about 4 years ago and I have no idea where I found them. I located them with a Google search and that's all I remember. I had to buy 10 of them.

There are circuit breakers that can be plugged into the fuse board in place of a fuse -- for example:

There are also Maxi fuse to ATC fuse adapters, and slow blow Maxi fuses are readily available.
