Aqua-Hot failure on 2015 Phaeton QBH

[DennisJM]

Good Morning. My Aqua-Hot system on my 2015 Phaeton just quit working in the Diesel mode. It still produces a limited amount of hot water in Electric mode. Not enough for a shower. The Diesel mode will run (but sputters a bit for about 45 seconds) and then quits. Any ideas? Should be covered under warranty, but in Northern Minnesota and do not know where to go from here. Thanks for any advise. Dennis

Call Bob Tiffin for the name of a local service tech.

And join the TRVN Forum... a much larger forum of Tiffin drivers.

Be sure you have more than 1/4 or 1/3 of a tank of diesel fuel! The genset will not run if less that that and the Aqua Hot may not either!!!

There was a bad run of the pumps for the Aqua hot systems. 3 of mine have failed. Tiffin will send you a new one or you can get it replaced. Most likely it is the stir pump if it does not heat on electric. And it gets run the most. Look for a revB on the new pump.
