THOR #19471
Tankless water heater

Newbie with new Delano. So far not at all impressed with the build quality, and hoping itís my lack of knowledge nd not Thor. Water pressure horrible, Even on city water, awning broken first week, leaks galore, refrigerator door swings open on curves, etc etc. and it drives like a rattle machine! I spent a lot of money for so many quality issues.
From day one the Girard tAnkless will heat bathroom sink water but shower heat shuts off after minute of less.
Tried removing pressure regulator and water filter, but problem remains.
And of course the manual says ďerror codeĒ will tell you whAt to do, but so far No error codes appear.
Any experienced folks out there with a suggestion?
Thanks
Jgfairfax

Try adjusting the Hot Water temp to around 100-105, then operate the shower with hot water only. That's how I've got my shower to operate with hot water consistently. When tankless hot water heaters detect a drop in pressure (e.g. when you turn to cold water up) they will shut-down.... by design.

Thanks. I think youíre right about water pressure issue, and Iíll try your idea as a temporary fix. But Iíve got to figure out the overall low water pressure on this new rig. Appreciate the help.

thor water pressure on city water

If you're on city water, you shouldn't be using the water pump; water pump for use only when using fresh water tank as the source.
Having said that, the water pressure is a constant problem in my Thor Delano as well, especially when not on city water. And the shower barely works regardless of which water source, and the lack of water pressure renders the tankless water heater almost useless.
These machines are just not built very well!
But again, if you're on city water, the water pressure comes from the city source, not from your water pump.

I couldn't tell from your message where the water was coming out, but Ive had a lot of trouble with my Gerard since new and have had to explore it some. If the tankless is spitting out water at the side, and not from the faucets or shower, Im guess you've got a busted water inlet to the tankless, or perhaps on the outlet side. Either way, if you cant see the source of the spitting when looking at the tankless from the outside, it is easily reachable, under the front dinette seat if thats your floor plan, and my guess is that the incoming line to the tankless has burst. If thats what you find, it is not too hard to disconnect the broken plastic hose, cut it back a little, and reconnect.

Let us know what you find; we'll all have the same problem in due time.

There is a water screen at the water pump. It should be inside the plastic housing that just twists off. The other water screens would be at the end of each water faucet where the water comes out of the faucet. They also just untwist. Also take the shower head off and check for debris inside that also.

You can also have a screen at the port where the hose connects to the coach, on the side or in a wet bay.

There's one where the water line hooks to the toilet.
