There Is Always Something Part Three

Hot water. Every time I use the hot water in our coach I wonder, will we have hot water today? For the past couple of years the problem with our hot water system was a substandard pump mechanism put out by ITR.

I don’t blame ITR for using cheap pumps. Sometimes a manufacturer produces a product at a lower cost and promises better quality. Or sometimes it is just not clear that the pump is a defective product and should be recalled until it gets out in the field in large numbers. Recalls then become very expensive.

Maybe as a company, you just wait for the pumps to fail. Perhaps under warranty. Perhaps not. And maybe not every pump fails. At least not right away.

Oh. And you can charge a lot for a replacement pump. A bit like a software subscription model. Incremental revenue after the initial sale. And, it makes the customer appreciate a quality replacement product for their coach.

Enough venting about defective hot water pumps. We have new ones in the system now and I expect that the mean time between failure (MTBF) will be better than the old design. The MTBF of the old design could be measured in days. Hopefully the MTBF of the new design is measured in years.

I digress.

Sorry about that.

What was I talking about? Oh yes. There is always something. On our trip from Florida to California we had a few, mostly minor, issues. The first was with our leveling system. It took multiple attempts to convince the system that all the jacks were retracted. Still unresolved. The second was with a plugged roof drain. Easily resolved. Messy, though. And I got wet.

And now, part three. A red light. I hate red lights. This red light has happened twice since we arrived to California, a heater module fault.

How did I know to check if we had a heater module fault?

No hot water.

So many times we have encountered no hot water in our coach.

What to do.

I went out to the bay that houses the main burner. This is our Oasis system that provides heat for our coach. Sometimes.

I did not really notice anything unusual here. No red lights on the front panel.

With my incredible knowledge of all things related to computing, it only took a moment to resolve this issue.

I deployed the BRS protocol.

This is a deeply held secret guarded by the few elite technology gurus in this world of which I am one. I learned about the BRS protocol many, many years ago.

Because I am now retired and no longer need to demonstrate my mastery of technology to any and all, I can provide you with this secret knowledge that has served me so well when facing mysterious technical issues:

The Big Red Switch (BRS) is a physical or metaphorical switch or button for which activation has ominous implications. A Big Red Switch is always very visible, and may stand as a warning itself as it is often designed to only be used in extreme situations. As such, the term has become a metaphor for extreme situations such that when an emgerency arises, someone might say “pull the Big Red Switch.”

Most often the Big Red Switch is a last resort in computer security, most specifically in mainframes or servers that have come under an attack that cannot be stopped and thus must be shut down. The term may also refer to major system resets.

The Big Red Switch may also be called the Big Red Button (BRB).

There wasn’t a BRS, or, for that matter, not even a BRB visible on the Oasis unit. There was, however, a RESET button.

I pressed it.

The coach promptly exploded.

But at least we had hot water for a few moments during the subsequent fire.

No, no, no.

The coach did not explode.

The Oasis system reset itself. The red light on the Oasis panel went dark and we had hot water again.

For about a week.

Then, another red light.

Then, another BRS protocol.

Then, hot water resumed.

I am thinking that I need to give ITR a call. I hate giving them a call because it costs me money. Usually several hundred dollars.

Given that we have been in the coach full-time for the past six months, it is probably time for the five-year service.

That is my guess although I thought we had a few more years to go before the five-year service.

In the meantime, if that red light comes on again, I will continue to invoke the BRS protocol.

Until the BRS protocol no longer works.

    OMG My Candian Buddy u got be kidding! Maybe Dutch Star made a special option for u to have hot water! Always remember what ur American Buddy once told you! IT ONLY COST A LITTLE MORE TO GO FIRST CLASS!😊😊

    “I thought we had a few more years to go before the five-year service.” With full-time use, that 5-year clock counts down way faster! The following procedures will be much more effective than your BRS! 😉

    Recommend you first watch & follow these videos: and With lots of use, checking and cleaning the burner chamber becomes more important (briefly shown here:–IA). My Hurricane (close cousin of Oasis & also made by ITR), periodic flushing and replacing the boiler fluid is also highly recommended. I use Camco Mfg Gal Boiler Antifreeze (Pack of 6) 30027 Auto Anti-Freeze Lastly, a quick search found this older Oasis Manual, yours may be a newer model:

    After tackling your Winegard Issues, the Oasis fix will be a piece of cake for you. Good luck with it!

      Oasis should include the directions to replace the pump. It is pretty straightforward and definitely something that you can do yourself. Unless you want a lot of fluid spraying about, you will need to get a clamping tool for the hose that feeds the pump. Despite being careful, I still had quite a bit of fluid leak out. You may want to make sure the area is clear just in case some fluid winds up getting dispersed.

      The job took about an hour or so. The longest part was clearing the area in front of the pump housing and then putting everything back. We had a 4018 so there was not much room in that basement to work on the task.

      Otherwise, yank and replace. We had to replace all three pumps. For the older pump design it was never a question as to if they would fail, only when. The newer design seems more robust.

      Good luck 🙂
