Intermittent problems can be a real bear to diagnose and fix. After years of chasing a very similar ghost, I replaced the Webasto controller with the Beckett controller as described on this forum. It has never failed to light or relight since.

Something to think about

If the motor/blower is running that means motor is turning and should rule out a bad motor. The problem could be that the fuel solenoid valve is beginning to fail. Maybe not opening when hot and it cools off enough to operate by the time you cycle power. Other thing that heat may effect is the ignition coil.

When the unit is heating but not finished you could turn the control off and back on the unit should fire back up within 30 seconds or so. I would try this a few times to see if the problem is caused while the unit is hot.

Richard , We did install a new controller .

Allen , I think the plan remains to replace the thermostats first . Not sure we replaced the solenoid valve but wee will keep following Aqua Hots flow chart and I figure that will show up . As I said she will cycle once but not turn back on until the switch is turned off then on .

Al,

I don’t know how interested you are in this exercise, but I have something I will loan you to help identify the problem. My AH was so vexing, that after unsuccessfully throwing parts at it, I bought a data logging module to record data to the split second. I hooked it to the ignition circuit, the flame sensor, the on off light, and the thermostat. It would tell me to the 1000th of a second which of those circuits caused the fault. It was only then that I saw the dang thing was shutting down for no apparent reason. That’s when I replaced the controller. An AH repair person had warned me about the reliability of the Webasto controller so I decided to spend 1/5 of the money. The other thing was in installing the controller, I noticed the Webasto wiring was undersized and totally cooked. So I rewired with heavier high temp wire. I live directly opposite you on the other side of the state. If you want to drive over one day, you can park a 45ft rig in my drive and we will take a look with the high tech snooper

Those controllers can be bad when you get them. Personal experience. Try borrowing a known good one.

When my photocell went bad on my Aquahot, at first it would light, run and heat up as it should. Then when it shut off because it was up to temp, it would not relight unless I cycled the switch. The green light at the switch on the dash would go out, even though the switch was on, after it attempted to relight after running.
Eventually as the photocell failed, when you selected the Aquahot on, it would start and light and run, for about 15 seconds, then it would stop burning, as the photocell was not detecting a flame, and would shut the fuel off. The motor would keep turning even though there was no fire.
I had to spend some time watching the Aquahot, and how it ran, to troubleshoot exactly what was happening, and use the trouble shooting guide.

Here you go. https://www.dataq.com/products/di-1110/

The only thing that you have to do is build a few circuits with resistors to drop the 12+ Volts of the AH down below the 10V that the logger will accept.

It takes an afternoon to play with the software and familiarize yourself with the outputs that work for your application.

Here is a copy of one of the runs I did.

Well I think we have this fixed . That is Don fixed it , I did however sit by and offer my opinion We finally were able to purchase the thermostats from a HVAC store . Not so simple as they sell only to contractors . However as we were heading out the door a customer offered his account for the purchase . So I would say the day started off well . So Don installed the t stats and after some testing it now seems the unit will cycle . Keep in mind the temps here are mild so maybe the real test wont occur till we are in colder weather .

I also want thank all who have posted and called me to assist . All of your thoughts and ideas played into our repair . I even had a call from Mike M out west who is over Larry's . Mikes advice based on 30 years in the HVAC business was lets say grounding . It's good to have a basic understanding of how something should work . . Larry even sent positive energy my way ??? Man what has the West done to this New York native Again thank you and I will either open this thread with more issues or close it with more facts on the issue . Thank you
