I have finally fitted my webasto heater and now have another prob, when heater is fired up i also press the rest button which switchs on the elec coolant pump and the interior fan, this can be done via a relay on the webasto unit but i wanted to keep it as a seperate unit.
Now when the webasto is running and the elec pump is running and the duo valve is making slight clicking sound but no hot coolant is getting past the valve.
So it appears the duovalve is not flowing any coolant as it should do, then webasto heater detects overheat and shuts down.
So any ideas on the valve to get it to open? if its not already.
I have the coolant flow the correct way around, ie webasto outlet to the duo valve.
