Try draining the grey tank first.

Then check for a plugged line

How is your weather, could the "P"trap be frozen? I get water in the shower when the gray tank is full. also when soap/hair build up in the drain.. I unscrew the drain cap and clean out the crap..

As this is an '04 unit, may we assume it worked previously?????
New purchase???

Make sure the gray tank is empty. If so use an appropriate sized hand operated snake to clear the drain.
