Winterizing a Splendide 2100XC washer combo
This is the first time I've attempted to winterize an RV washer. I followed the instructions in the Splendide 2100XC manual:
Optional Winterization Instructions
If you’re currently pumping antifreeze through your fresh water system, you canfollow these steps to winterize your washer-dryer:With machine power OFF, turn WASH TEMP knob to ‘HOT’;Advance Cycle Selector to position ‘3’;Press ON/OFF button, then press START. Let machine fill until the drumturns (could take up to 1 to 2 minutes);Press ON/OFF button to turn power OFF;Advance Cycle Selector to ‘Spin’;Press ON/OFF button, then press START. After letting antifreeze drain completely from drum, press the ON/OFF buttonto turn power OFF. FINISHED.
After I completed the job, I began to think about this, and wondered if I had, in fact, cleared all of the water out of the cold water line. Prior to winterizing, I did drain all of the water from the low point drains, but by turning the selector to HOT, I was thinking that the cold water line might still have water in it.
Today, I called the tech support folks at Splendide. They were very helpful. They explained that for the 2100XT (the 2100 is different), with the selector on HOT and cycle "3", the first thing the washer does is pump liquid from the cold water supply line into the drum. Then it sits for close to a minute, and then drains this liquid out of the drum. Then, it pumps liquid from the hot water supply line into the drum, sits for about half of a minute, and then starts turning the drum. As long as you let the cycle progress to the point that the drum starts turning, it will have pumped liquid from both supply lines.
For safety's sake, I decided to re-winterize my washer. After buying 3 more gallons of pink stuff, and dumping it into a 5 gallon bucket, I hooked up the battery, started the generator, and turned on the water pump. I set the washer to cycle 3, and to HOT. Then, I turned it on and pushed start. I heard the pump turn on and liquid pumping into the drum, but the level never came up high enough where I could see it (I believe this was due to air in the lines from the pink stuff settling). After a brief pause, it pumped out the liquid, just like the Splendide tech advised. After another brief pause, I heard the pump start pumping liquid into the drum again, and this time the level came up high enough that I could see that it was pink. After another brief pause, the drum started turning. Then I turned the washer OFF, turned the cycle to SPIN, and turned it back ON, followed by START. It promptly drained the pink stuff from the drum. Then I shut it off.
Since I never saw the pink stuff in the first fill, I decided to run the above cycle again. This time, I saw pink on both fills. I am now confidant that the washer is fully winterized.
I thought that this explanation about what is actually happening might be helpful, above and beyond what the manual says. As long as the cycle progresses to the point of the drum starting to turn, and then draining it with the SPIN cycle, AND you can see pink stuff on both pumping cycles, you will have cleared both supply lines from any water. Each time you run the cycle up to the point of the drum turning, I found that it consumes about 1-1/2 gallons of pink stuff.
Even though the water temp is set to HOT, it is pulling from the cold supply first, and then the hot, IF you are patient enough to let it progress to the drum turning point.
