Ice maker in 310RL

[justdee]

I have a question regarding the ice maker in my 310RL. I cannot remember what the tech told me the day I took delivery. That was back in October and I called the dealership on Thursday to speak with a tech but they are all busy with a big rv show in Nashville this weekend, so they were unable to get back to me, so I'll ask here.
The manual states the water line is not connected at the factory, so I'm assuming it is up to the dealership to make that connection? I am not sure if it is connected or not and if so, since it is not making ice, is there a shut off valve I should look for?
The unit is bolted/screwed in place to prevent movement, you'd think they would not want the owner to take the unit out to get to the water line, but I do not know.
Any help, at least until I can get ahold of a tech?
I do not have to have the ice maker working for my first trip coming up, but I think I'd want it to be working before the heat of summer arrives. Does any one else use their ice maker or do you just buy bagged ice?

Look under your kitchen sink, there should be a small water line with a valve under there that feeds the ice maker.
We just buy bags of ice, I am hesitant to use it only out of the fear of not getting it winterized properly .
The bagged ice works for us.

THANK YOU!!!! I just went out and looked and sure enough, there was the cutoff valve. I turned it and then dropped the wire bar on the ice maker, so we will see if there is ice tomorrow.

I have not winterized ours. Knowing I was going to buy a 35' trailer, I had a big concrete pad poured, with a 3" sewer line laid in the concrete that then runs to my septic system. Then I had a carport built to protect the RV from the weather and sun. Next, I had 50 AMP service ran to the column right next to the power hookup. Then they ran a water line to the carport so I have running water.
I just keep the power on, the fireplace running at 70 degrees and I put a small heater in the storage area with a temp set at 65 degrees. I disconnected the water line so that's not an issue. I put some water in the fresh tank, about 2/3's of a tank. And I have the electric water heater on as well as the tank heaters.
We have been getting down to the 30 degree mark a few days but it doesn't stay below freezing all day. I have a blue tooth device in the storage bay that allows me to monitor the temp & humidity, then I am constantly checking the temps inside the RV and I have a dehumidifier running inside as well. Heck, I've been sleeping out there on these colder nights just to 'test' it out. My friend laugh at me but I don't care, I love it.
Our first road trip is on the 16th, so we are ready and looking forward to it.
Again, much appreciate the information.

Your welcome, keep in mind that the ice maker line goes into the underbelly and is bundled with the wires that extend and retract with the slide, so it is exposed to the elements under the slide. You might consider installation some Insulation on it if your going to be in colder climates.
Also, and this is strange. While the refrigerator runs off of 12 volts DC, the ice maker runs off of 120 volt AC, so there must be an outlet hid behind the unit that is tied to the breaker panel.
I also have read several comments on this forum that the line isn’t hooked up from the factory, so you might double check that you are leak free.
Hope you have ice in the morning!

All good to know, thanks. I crawled under there last night and found the line and it was exposed just as you mentioned. I may wrap it with a electric heat strip, or just not use it during the winter, if at all.

Do you get ice yet?

 

[Terri&KevinGates]

Unless you asked the dealer to hook it up they probably didn’t. If you look in the bottom of the cabinet to the right of the stove there is a divider screwed to the floor. The connection is behind that. There is a shut off with a nut and ferrule connection for the 1/4 inch line going to the icemaker. We never hooked ours up just buy bagged ice. As far as winterizing it’s not recommended to run antifreeze through it. Just shut it off under the sink and drain the line. Drain is under the middle of the trailer where the sink is. Our last trailer I found it helped to disconnect the flex line that runs under the slide.

I sure appreciate all the great information. Yep, I found the valve under the sink and turned it on. Then I saw Bryan's follow up post saying the line was exposed to the elements, so I went and shut it back off, but by that time, the line was full of water. I crawled underneath last night and found the line, did not see a leak, and just left the ice maker bar in the off position. But this morning, with temps being in the 60's today, I went ahead and dropped the ice maker bar back into 'make ice' mode, but I left the water line closed figuring there should be enough water in the line to at least make some ice. Sure enough, just got in from church and I checked. It worked, there was ice in the bucket.
Now I'm in a dilemma. We have a cold front coming in a few days, temps are predicted to drop into the 20's at night. I'm worried that the water line I filled up after turning on the valve will freeze.
I will go out after the ball game and check for that drain valve that Kevin mentioned. My other thought was to wrap the water line in foam insulation or put a electric heat strip on it.
Again, I sure appreciate the advice, thank you.

I suspect the drain Terri and Kevin are referring to is the system LOW POINT DRAIN. This would consist of two PEX lines, one red one blue with shut off valves. It is designed to help drain your entire water system when required. At this point insulation might be your answer to protect the ice maker line from freezing. Or try to purge the water from the line by disconnecting it under the sink and at the refrigerator connection thru the cabinet access others have mentioned.

 

[justdee]

Terri/Kevin, is this the drain point you were talking about?
It is underneath the kitchen area and that line does run underneath the slide out. It is the only hose that I see that could be the water, but this fitting looks more like a hydraulic line to me?

 

[2 Allies]

That looks like the propane gas line.

 

[Terri&KevinGates]

Your first picture is propane lines. Probably the one that goes out into the slide for the stove. Second is the fresh water tank drain and over flow. I went out and took a picture of mine. We have a 2022 310RL. It shows my Fresh water drain and overflow with the ice maker drain just behind the rear axle. This is seperate from the low point drains that are just behind the sewer outlet. If you look close you can see the low points just in front of the front axle.

 

[justdee]

Thanks, I'll go check it out. Maybe I just overlooked it. I was focused more on the slide out.

 

[Jim J]

good right up i need to drain my ice maker line on my 2024 375 rd maybe will be the same i hope

 

[BryanValRox]

I'm a little confused regarding one issue -- there is a white line in cabinet next to fridge not connected to anything. Is that the water line that still needs to be connected prior to turning on the water under the sink?

I checked under sink and both cold water lines are open. One is the sink but what is the 2nd line? Its not to ice maker or I would have a water mess already.

Inlcuded are the 2 cold water valves under sink. Both open

The white line would certainly be for your ice maker. Ours runs from the frig, to a tee connection under the kitchen sink with a separate valve.

Many have reported that this isn’t connected by the factory as standard practice for some reason.

Ours was in fact connected , however we choose not to use the ice maker for reasons related to winterizing and our style of camping.

I bring ice from home and then buy bags As needed.
I don’t drink the water in the coach so I don’t want the ice. Plus I really don’t want that line to start leaking back there? One less thing to worry about For me personally.
Thats just my preference.🎩

Good morning! For what it’s worth I was in commercial construction General Contractor for 45 years that included some multi story mid & high rise apartment & condo projects. On those types of projects our firm would “exclude hookup of any refrigerator setup that included an ice maker because of the HOA & Bldg Owners law suites. That responsibility was left up to the Owners bldg management team. May be why they are not connected by the factory??
Now in an RV,,,traveling many miles,,,shake, rattli’ & rolling on the road,,,,,some layouts having plumbing in slides,,,I would consider the opinions offered above to be very wise advice. Am certain other members have other opinions for your consideration as well,,,good luck & enjoy your adventures.👍🍀
