Oasis summer loop pump not working during winterization. Okay?

I didn't manage to get my Oasis summer loop pump replaced this summer so am winterizing without it working. As I understand this pump only pumps antifreeze and will still allow pink stuff to circulate thru all the lines with the fresh water pump as usual. Never thought about this before and these little obstacles just seem to keep cropping up.
Hope I'm doing alright, but could turn on the other pumps with the switch on top of the control board next to the Oasis unit if necessary.

Thanks again to all you Oasis experts.

You are correct. The Oasis pumps circulate Oasis boiler fluid (i.e. not water). An Oasis pump not running will not affect the winterization process. It will effect the Oasis ability to provide heat to any circuit / area covered by the non operational pump.

Quick test to see if your summer pump is bad.

Quick test to see if your summer pump is bad.

Turn on your Burner as well as your two heating elements.

Check to see if you have continuous hot water, for a few minutes.

If not, turn the switch located on the top of the silver control box next to your Oasis, (allows to run all three pumps, both loops and the summer pump, if working.)

Check to see if you have continuous hot water, for a few minutes. If you do this time your summer pump is bad.

Turn off the bypass switch and order a summer pump.

You can also turn on your heat and it will do the same thing without having to turn on the bypass switch.

No hot water unless switch on top of silver box panel is turned on. Red light on Zone Fault in panel over passenger seat, blown fuse in silver box, and red light on silver box at Summer Loop. ITR confirmed summer loop pump has bad wiring. Ordering a new pump wouldn't help me as there is no way I would be able to crawl back in that compartment then be able to get back out. Watched a mobile repairman do it once 2-3 years ago while traveling. Only a very agile limber thin young repairman can do this.

Will have to go back to dealership next spring for the repair, and hope the new pump will last longer than this last replacement.
