 the correct part # is ELE-PC4-010-AA , Price is more like $400+
part # you have is the old #
Probably a used #,

[Les Brandt]

Orman,

The two that I found are the same part number as what mine is. One is a new part and the other is a used. It's my understanding that the model you described ELE-PC4-010 is the latest but must be modified to suit ELE-PC4-008.
Would it not make sense to get the exact model if available?

Les
No Modification, all the same,
Buy the cheaper one

[Bob Jae]

Les this is the board I have.  $200 which would include priority shipping.

[Les Brandt]

Thanks Bob. Yours is a ELE-PC4-009. Not sure if it'll work. I'll do some homework.

Orman, what do you think?

[Orman Claxton]

Yes, It will work,
If is one of the updates

[Les Brandt]

I did get on the Hydro Hot Guru's website and Roger confirmed as Orman did. My panel needs replacing. (Not that I questioned you Orman, he just took longer to answer my thread question).

He had me unplug all 4 wire harnesses from the panel. He said that if I unplugged all 4 and the low battery fault light stayed on, it would confirm my panel would need to be replaced. I thought I would pass this info on.

I may not be finished with the issues yet, we'll see what happens after the controller panel is replaced, but I'd like to thank you all, especially Orman, for taking the time to help thus far.

Bob, I sent you a PM regarding your panel offer.

[Les Brandt]

Bob Jae is sending me his spare panel. Thanks Bob!

Hopefully all will be well.

I'll keep the thread posted.

[Les Brandt]

Well the new controller panel from Bob worked. No more "low battery fault" light.

When I hit the interior diesel switch in the kitchen, I heard a "whir" sound for about a minute and then it quit. What else should happen? Do I sit and wait for hot water? If so, how long? What else should the unit be doing? Should it continue to "whir" till the water is hot?

Man.....I feel like such a Greenhorn, but I've never had one of these systems and I don't know what to expect.

I turned on my water pump and one of the interior heaters so that it would call for heat. Not sure if that's required or if it just heats up.

Les,

Turn the diesel switch off, then back on...  You should hear the burner turn on after the wir sound... Go outside to the exhaust pipe and see what is going on.  Is it smoking, is it blowing air or is nothing coming out?

[Les Brandt]

I took the Hydro Hot cover off. It's the blower motor that's making the noise. Air is blowing out the exhaust. The burner doesn't fire up after that blower shuts off.

[Karl Welhart]

Les,

Is the light on the diesel switch flashing after the blower motor quits running?  Is there any smoke coming out of the exhaust pipe?  If the light is flashing on the switch, turn it off then on again.  Do you have at least a 1/2 full tank of fuel?

[Les Brandt]

Lucky me. The light is burnt out on the diesel switch. Can't tell if it's flashing!
No smoke coming out of the exhaust. Just over 1/2 tank of fuel.

I was told I may need to cycle it a few times as it hasn't been running for a long time and may be starved for fuel.

[Karl Welhart]

Les,

Yes, that is true.  Try it a few more times and see if the igniter fires.  The light just goes out on the switch and does not flash.  This normally is an indication of no fuel in the lines and will take a few tries to get it to fire.  Has the nozzle and filter been changed recently.  Those could also be causing you this kind of problem.
