FWS will not go all the way in

[ARD]

Okay, I'm making a post for friends who will eventually join the forum. Meanwhile, it's a Sunday and they can't get their FWS to lock in. They have a 2020 DS 4369. Background...in the last several weeks they brought the slide in and broke their tile floors.

Today, they tried to bring their FWS in and it comes in all the way. However, when you let go of the button it makes some noise and it pushes out about 3/4 to an inch and stops. They tried it about three or four times and it does it every time. Any ideas? As always, thanks for your help.

Wow, that's ugly and unfortunate. I've heard of this before and from what little I know of this system I've heard it's some HWH component failure. Again, no experience or anything of value to offer here but hopefully others will chime in that know that slide and how it works. I don't know if there is anything to check with the related hydraulic system, fluid levels, etc.?

I hate to suggest calling Newmar for the 24/7 on call tech but they should probably do that if not done already.

We have and they will hook us up with HWH in the morning. Hoping this is something easy we can do at our site. Thanks!

Already been done. They got MARY and she is of no help. She will connect them to HWH tomorrow.

From my googling for this issue it appears it may be a bad solenoid. I'm still researching...

Ahhhhhh! Is that you, my friend Wendy and Don Brown! Welcome to the Forum!!! To all fellow Newmar family peeps and not Newmar...welcome the Browns and THEIR FWS problem. I'll let you take over, friend.

A google result suggested:

Run the slideout all the way and hold the switch for 20 to 30 seconds after the slide had fully extended. Then bring the slide in and again hold the switch for 20 to 30 seconds once the slide had retracted fully.

Make sure fluid in HWH holding tank is not low or leaking, it can cause air to be introduced into the system.

In general, not being a newmar owner. It sounds like a limit switch issue. It could be a simple adjustment or a symptom of a broken slide component that could cause a adjustment problem.

If it goes all the way in and than backs out, it looks like the locks do not engage?

I believe the HWH FWS is held in with hydraulic pressure, not locks. Don’t hold me to that, however.

Morn than likely solenoid issue, not closing valve once limit achieved. But the tile issue is a Newmar issue to fix, so make appointment at mothership, and let them fix it all at once.

Welcome Don and Wendy to the forum, sorry it’s with a FWS issue. I will be following and hope you have some assistance tmo

Sorry to hear about this problem with your new coach. I wonder if the slideout shape/floor is sagging due to the weight of the refrigerator right there and cracked the tiles?

Thank you for your help. We are on the road. Talked to HWH this morning. They thought it might be a contaminant in the solenoids. They had us shut the two solenoids in the 4th bay (behind vac system) by turning the lever 90 degrees (down). Pushed the In button on the slide for 10 seconds. The slide doesn’t move, but motor runs flushing the contaminant out. They can’t guarantee it won’t happen again in which case we will need a new solenoid, but are hopeful.? Hope this helps anyone else out in the same situation and thank you for the tips.

Great to hear and thanks for sharing the info for others to learn from. Safe travels.

I don't know the HWH system but here are a few thoughts/concerns:

1. Can the FWS be stopped if you see that it's not going to clear the tile to avoid damage in the future?
2. Can HWH improve the system so it detects this situation to avoid damaging floors?
3. Can it detect it hasn't lifted the required amount prior to the slide moving in?
4. How much is a replacement solenoid and how hard is it to change? I personally could not risk floor damage wondering if the solenoid is compromised or not.

Destroying floor tile is saddening and having to have unsightly damaged tiles until you can get somewhere to have it replaced is nothing any of us want. My concern is how to prevent this, and does HWH need to do something to ensure this can never happen again?

 

[NWIP]

I was told you can stop the FWS movement, just don’t stop during the lift phase. Since there are two of us I always stand outside and DW pushes the button and to release if she hears me bang on side of the coach.

Also reading at other location where others have had the same issue that with these latest slides you need to have the engine running to provide full power to the HWH system. Not just plugging it in or running the generator.

I had wondered why North Trail in Ft Myers had a beautiful 2020 Mountain Aire with three long tiles at the edge being replaced.
