Love my Atwood water heater
I just bought this water heater in replacement of my 1988 Atwood 6 gal LP with DSI.I figured that after 22 years of faithfull service...it would be time for a new one. I noticed that this year, the model is much more silent and
they have changed the dual probe to a single one in the ignition module. This makes better sense as the former one
needed to be exactly spaced just like you would find on a spark plug. Overall, very satisfied and no need for an anode
rod since it is an aluminium tank !

Atwood water heater
Old water heater sprang a leak, of course while away from home. Ran down to local CW and thankfully had in stock. Taking old out and installing new wasn't that difficult and only needed a few tools. However, the water heater wouldn't fire up immediately, came on for a few seconds and then off, repeat several times. Let sit for extended time and did get it to come on and stay. Then after a day it wouldn't function properly, off and on for very short periods. By then it was Monday morning, called Atwood and after lengthy hold period finally a tech. Turns out this one has a faulty circuit board, a number of units were sent out with this problem. They offered some options, send me a new one or I go find a new one locally and they reimburse. Selected they send me a replacement. Awaiting the new board now. Had to call them back the next day and after a very lengthy hold time elected the "they call me back" option and they actually did, twice. Gave a 3 star rating because of the bad circuit board from the get go.

Perfect replacement
The new water heater slid right into the RV to replace the original. Nice to see someone build a product that is user friendly. Fired right up and works great.

Atwood part number??
This water heater is a G6A-8E model, aftermarket part#96121
Date published: 2020-08-17
does this replace model g6a6
Direct replacement of a G6A-6 is an Atwood G6A-7, <a href=https://www.campingworld.com/atwood-water-heater-6-gal-lp>item# 3687</a>. Item# 3690 is a G6A-8E model water heater that has electronic ignition instead of being a manually lit pilot version like the G6A-6/7 models.

Does it directly replace GC6AA-9E?
No, this water heater is a G6A-8E model. A direct replacement would be a GC6AA-10E which can only be obtained through an OEM dealer of Atwood products, we only deal in Aftermarket. The closest we have to a replacement for a GC6AA-9E is a <a href=https://www.campingworld.com/atwood-water-heater-6-gal-lp-electric-dsi>GCH6A-10E</a> which has all the same specs except for an added Heat Exchange feature.

Does this have a built in by-pass?
No, RV water heaters rely on external plumbing from the RV for bypass configurations. <a href=https://www.campingworld.com/quick-turn-by-pass-kit>Item# 15717</a> is a bypass kit for RV water heaters.
