Thanks to Rudy's patience on phone calls educating me, and sending parts (motor and clutches so far), we are back in business with diesel burner on the Aqua Hot.

The new motor is the silver one.

A new electric element is in route, I ordered a 1.5" socket on Amazon, have a impact wrench I can borrow, have 4  5 gallon buckets and a fluid transfer pump in hand.

I'll post pics when I do the electric element - probably next week.

I also have on order a new mixing valve to transfer the guts to mine - handle sheared off during service.  If I have any energy and time left after the electric element I will tackle that as well. If not it can wait unti next burner service.

I am considering not putting the outer metal covers back over the aquahot, and placing them in my storage shed.

Any pros and cons to doing that?

For myself, not putting the left side cover on has decreased the heat around the controller ( I still have the black plastic ...will be changing it out to the Aqua hot brand one that is solid state) and at the same time provides heat to the Aqua hot bay in My Canadian winter environment. The heat of the AH adds significant heat to the bay so I do not have to add electric heaters

I run with mine removed. I think it helps in keeping the bay warmer in cold weather also.

My covers are off to let the heat out from around the control unit and to make it easy to check a fuse or any other service.

Dan, as you have time, turn the control unit upside down to put the plugs facing down.  Any moisture will run off of the box, not down into the box.

Dan;  on your mixing valve, you can just replace the guts and be good to go.  I did mine when I had the burner assy off for service.  Easy to get to then!  Glad to hear you were fixed up by Rudy!  He is the best and gives so much to this forum of his time and expertise!  That is what makes this forum so great, friends helping friends!

I wish I had access like you do. Not so easy on mine.

Changed  mixing valve and electric element in the AH today.

Swapped the "guts of the mixing valve. Pic of old and new temper valve. Different design but works fine.  Getting the old one off was difficult. Vice grips as tight as I could make them, and beating on it with a hammer was required.

Old electric element was fried.  Pic of element.

Used Rudy's advice on the element. Shallow drain pan under the coach, liquid transfer pump to move coolant to 5 gallon buckets as it filled (15 to 16 gallons total).  Impact gun to break old element loose (1.5 inch socket. 1/2 inch drive) (then use ratchet to remove and replace).
