Winterizing Splendide Washer/Dryer

I am attempting to winterize my washer by running antifreeze through the main water pump to the washer. This worked fine with my previous motorhome but with this one I can't get enough antifreeze into the washer drum. It seems like the pump doesn't have a good prime since I can hear it sucking air. How can I assure the pump has a good prime?
Thanks, Pat G

Winterizing is the same regardless....
I'll assume you have a hot water heater and not a hydronic system such as an AquaHot.
I'll assume that if you have a hot water heater it's bypass is set for winterization.
I'll assume you have a short hose from the INLET side of the water pump that has a valve at a "T" to allow you to place that hose in the pink antifreeze and when the pump is energized it draws from the gallon jug rather than the fresh water tank.
I'll assume all your low point drains are already drained and shut off.

Once hooked up to the gallon jug, with all water taps closed, energizing the water pump should begin to draw antifreeze into the system and the line should build pressure and the pump will shut off. Go around to each faucet one at a time and run the hot until pink runs, then cold, till pink runs out - repeat for each faucet - don't forget the outside shower, don't forget the icemaker if equipped. The same goes for the washer/dryer, simply place it into a wash mode and it should begin to fill, once pink antifreeze is entering you can shut the unit off.

Of course, you have to get antifreeze into the waterlines leading to the washer, but you have to do more than just get antifreeze into the drum. You must also get antifreeze into the washer's drain pump. That is done by activating a spin cycle after antifreeze is in the drum. HERE is a link to the winterization procedure for recent Splendide models. If you have a different brand, check the manufacturer's website.

hi guys, heres a tip for those of you with an on board air compressor. you can connect to you water inlet and blow every drop of water out of the system including the ice maher and washer. i regulate my air to 50psi and have a solid connection so that i can bleed the water completely out off the pipes turn on the washer and wait and when it calls for water the valve will open and you will blow those lines out. then when done blowing out the lines cycle a 1/2 gallon of antifreeze through the drum and let the pump pump it out and into the trap and your all set. then continue with the rest of the process draining the water heater etc. i'm a retired master plumber and have winterized many buildings by blowing out the lines without problems dont forget to break the connection at the pump and drain it. i live in new england and have been winterizing my rig this way for 19 years and have had no problems and i dont have to deal withflushing out my lines when i get ready to uise the rig happy holidays hohohohoho
