Boxxer 421 Dumping water into Tank

[tman7]

The title says it all for no reason that I can see My waste tank fills up pretty rapidly, my temps are about half what they should be . Haven't had a chance to study the schematics in the manual but was hoping someone here could suggest a possible or most likely cause. The machine has about 2400hrs, other than the PITA Chem system I've had no major issues. Thanks for your input.

sounds like the Dema valve on the waste tank is stuck open

I have just the opposite problem. Won't dump at all.

New motor is going in next week also. Damn, I hope that goes well.

How many hours were you able to get out of your engine? just curious, Im at 2400 hrs, change oil and filter pretty regular.

 

[packfancjh]

are you saying that you are overheating Dirk? Is the machine shutting down?

Therm valve is stuck.....

 

[Blue Monarch]

No...it gets a bit too hot, but it doesn't shut down. No biggie....just another quirk. Nothin a hack can't handle

 

[Joel D]

Yes have to replace valve. I think i replaced both. Do a search i think theirs lots of info. Common problem, they wear out no big deal.

Thermostat could be bad or just need adjustment. At what temp does it begin dumping into waste? I have a simple HX unit and it has a tiny screw on the back of the thermostat that allows for fine adjustments. Mine dumps at 220 to keep from overheating but you can change it SLIGHTLY if you're CAREFUL. If it's dumping too soon but operating correctly otherwise, that could be something to check.
