First trip

[Enjoying rewards]

Having been through at least 12 camping units and 50 years of travel camping, we recently purchased a 2026 310rl. From delivery ( November 2025).through departure to southern temps, we spent time sorting and eliminating years of a camping collection, including many self help items.
As we are now ending our first week in the sunshine state, I needed to dump and clean waste tanks. This unit has motodrain rocker switches, connected to electric valves. Previous discussions identified the lack of operational support for the switches operation, and previously having problematic electric valves on a Winnebago tour, I wanted to understand the system, so I studied the motodrains on line and in the owners manual, little help was offered in either system.
That said, I did all of the prep to evacuate the tanks, my black showed half full, gray one ( shower and bathroom) 3/4 full, and gray two ( kitchen) showed full. I Started my process opening black with rocker, alls well, opened gray one , great, pushed gray two, no light on the rocker switch, no valve function. Check the fuse, blown. I explained earlier my previous purging, so I no longer have the collection of old style fuses With me..Off to advance, Napa, and midnight auto parts, and told not available, this fuse size is no longer a stock inventory, and you can order it on line…
I now have 53 gallons in the tank, gross water in the sink and a valve, closed…..I did what any camper used to the “ issues” of the many systems, switched the fuse from the other tank and got the switch to light and function, however no valve function🥵
I left this scenario with alliance on their help line, however, it’s Saturday and I’ve not heard back.
in conclusion, In your experience with Alliance, will they cover this under warranty If I use a local repair guy? My next question to y’all, is there simple access to the valve? Is this a simple fix or does it involve cutting the underbelly? I’m thinking to employ a local repair guy to do what needs to be done…your thoughts are appreciate, so thanks in advance from Vero beach😉

First, Congratulations on your purchase and Welcome to the forum. Vero is a great area and Happy you are there with your issue instead of anywhere north of there right now.
On our '24 385FL, there are underbelly access patches at each of the 3 tank discharge valves. You should be able to see them when you crawl under. Others with the 310RLs should be able to tell you which one you may need to access. Alliance will be able to support you but it may be Monday.

Good luck with your resolution,

Welcome and congratulations on your purchase.
Attached is the manual on what I believe to be the waste valves installed on your rig.
You might find it helpful if it applies.

Thanks Bryan!
appears that there are three access panels in the underbelly for valve access, naturally non were marked for relating to 1-2or 3.
third panel was it, for future reference drivers side forward panel is black water, passenger side forward gray one, driver rear gray 2.
If anyone chooses to get into the access areas, please be careful, it holds a fair amount of sawdust and debri, and gravity prevales🥵.
The gray two valve is really the most unserviceable and tangled in multiples of wire, 110, and 12v, piping, and hydraulic lines for the. Near Jack..
I was able to open the drain wide enough to drain the tank. Close the access door and make an appointment for next week at a local alliance dealer 28 miles away. Assuming the parts or needed repairs are quick, we should be washing dishes again late next week, interim, the restaurant business just improved in this area.
As an fyi, the fuse that is hard to get and required is a F4A250v, you may be best served to keep a spare.
thanks

Any chance you took some pictures and could post them here? Then if someone has this issue in future, we can link them back to your images.

Glad you were able to access the valves through the access panels. Good to know you have the skills needed in a pinch. Good luck on your repairs and still envious of your current location.
All the best ,
