I wrote something similar to this but received only a curt reply that I should take the unit to a dealer who would place the switch in a more accessible place at my expense. Bahh.
Your reviewer of the Winnebago Vista 27PE in the October 2017 issue of the "MotorHome" mentioned the dumping system as being "a small inconvenience that's offset by the livability of this coach." I must expand on a similar situation with my 2017 Winnebago Aspect 27J. The coach really is superb except for the dumping system that is the worst I've ever encountered among dozens since my first RV in 1973. In our Aspect the macerator system is attached to the grey water tank. To drain the rig completely one must: 1.
Start with two keys A and B where B is the barrel key. 2. Use key A to open the left rear hose compartment and remove the hose(s). 3.
Use key A to open the left mid-vehicle compartment; then unscrew the bottom compartment plug, take off the sewer cap, attach the hose (be careful of your head if the slide out is extended). 4. Place the other end of the hose in the ground sewer drain and secure. 5.
Open the black tank valve in the left mid-vehicle compartment and wait for the complete drain. 6. When black tank is empty close the mid-vehicle drain; else the grey water would back flush. 7.
Use key A to open the grey tank panel toward the rear of the vehicle and open grey tank valve. 8. Use key B to open the large rear "basement" door; we had to remove rear scooter carrier first. 9.
Push and hold the rocker macerator switch on left side until the macerator sound changes. 10. Close and lock large rear door with key B. 11.
Close gray tank drain (step 7) in panel toward rear of vehicle and lock with key A. 12. Disconnect drain hose from left mid-vehicle compartment and ground sewer drain. 13.
Replace both caps in compartment and lock with key A. 14. Place drain hose(s) in left rear hose compartment and lock with key A. There is one aspect to the Winnebago engineering that bears emphasis: there is no way to leave the hoses attached and rely on gravity to drain both tanks!
If you were to keep the hose(s) attached you still would have to do steps 7 through 11 at intervals dependent upon your production of grey water.
That means monitoring the tank indicators every day and draining if needed no matter the weather. Richard Johnson
