Luxury Coach Lifestyles - View Single Post - DIY- Do It Yourself Annual Aqua-Hot System Servicing Help?

Hi Les,

On my coach I had two separate issues that affected the shower temperature. First was the "cartridge" in the control handle (Grohe) of the shower. It has a little spring in it that is affected by temperature. It allows me to set a desired temperature regardless of the temp being generated by Aquahot. It had "worn out" and needed to be replaced. Talk to Newell, or get a part number and order online.

The other was the aqua hot mixing valve. It is a valve with a little black handle up under your Wesbasto unit. Mine needed to be replaced as well. It also is temperature "activated". I think that there have been several posts regarding this valve. (This is an inexpensive part, but you have to remove webasto to get to it).

Others can chime in on the annual service. (I had mine done by Newell).
