They are notorious for overheating issues. There are people who can probably diagnose much better than me, but if 5 seconds and shut off you may need to hold down the override while turning on for a good 10-15 seconds.

The ThermalWave we have in our company we had to move the computer outside the mount and pack it inside a cooler with some freeze packs otherwise it shuts off. As long as its cold it runs. Don't ask me what that means or why.

I'm assuming you already checked all the Usual Suspects such as fresh water box is full, fresh water float working properly, waste tank float working properly etc?

Here is a link to the manual.

engine is a nissan so it should last...Ive got older engines and the only times they shut off its because one of the sensors does it. Maybe check if youre getting fuel. Did you replace fuel pump? Clean out fuel lines? Clean filter? I dont know if that unit has the same relay that makes it shutdown my 405 has done that.

If I recall correctly they had a big design flaw with an undersized cooling system and have over heating issues.

Most who had them years back had to move on

There might be a thread here somewhere.. one guy was able to retrofit a large exhaust fan to keep it cooler

The company I worked at we put the computer in a freezer box with ice packs. Gave you about 6 good hours before it overheated.

Thanks it was the high pressure sensor, not more problems after that
