Westfalia Purifier OSD 18 Issue
Posted: Mon Nov 28, 2022 9:26 am
Good Afternoon,
Looking for some advice on an issue we have been having on Westfalia diesel oil purifier. Purifier shows alarm "WATER OUTLET FLOW TOO HIGH" and trips off. This alarm comes roughly about 5 minutes after the unit is processing fuel. Looking through the inspection port, you can see the bowl start to break over and then the alarm follows about 30 seconds after. Issues with the control panel have been ruled out, as we installed a bowl from another unit and there were no issues.
Things we have done so far:
-Tore down bowl and replaced all seals multiple times, including polyamide gaskets
-Checked all measurements for polyamide gasket height clearance
-Installed new water solenoid block and function tested (all good)
-Cleaned all water lines/piping as well as orifices and check valves
Looking for some ideas on what to try next. Bowl has had seals replaced multiple times during this troubleshooting so I do not believe seals are the issue. Shoots great during the startup sequence, just seems to lose the seal after about 5 minutes.
